ABSTRACT
International civil aviation has been one of the most regulated industries. Since the 1970s
however, the airline industry has been gradually liberalized, with domestic deregulations
taking place in the United States, Japan, and other relatively developed parts of the world.
The United States and the European Union signed the EU-US Open Skies Agreement in
2007. This agreement, which took effect in March 2008, liberalized the airline industry in
the North Atlantic. This research aims to find the effect of the EU-US Open Skies Agreement
on the number of passengers flying between the United Kingdom and the United States. I
find that the open skies agreement did indeed increase passenger traffic between the
United States and the United Kingdom by an economically significant margin. This finding
helps demonstrate the positive impact on civil aviation of international bilateral
liberalization treaties.
Introduction
For most of its history, commercial aviation has been one of the most regulated of all
industries.
1
After World War II, the Chicago Convention of 1944, at which the ICAO
(International Civil Aviation Organization) was founded, established a relatively restrictive
structure of government regulation of commercial aviation and bilateral agreements
between two countries regarding air services. The concern motivating this structure is that
the United States, given its powerful economic position after the war with the largest fleet
in the world and abundant military surplus, would be in an unfairly dominant position if
the market was left with free competition, hence the need of restrictive government
regulations.

For the past four decades, the developed world has witnessed the gradual relaxation
of government regulations in commercial aviation. The United States Congress passed the
Airline Deregulation Act in 1978, withdrawing government control of route rights and
price setting over the domestic airline market. In the 1990s, the European airline industry
was liberalized with the founding of the European Union and European Single Market.
Comparatively, bilateral deregulation in international aviation experienced a slower
development as it required a mutual beneficial deal between two politically liberal
governments.
In March 2008, the EU-US Open Skies Agreement took effect, removing restrictions
on route rights and air fare, allowing any EU and US airline to fly between any EU city and
US city. The agreement effectively nullified the Bermuda II Treaty between the United
States and the United Kingdom, which permitted only four carriers (British Airways, Virgin
Atlantic, United, and American) to operate between London Heathrow Airport and the US.
The agreement also allows for foreign ownership in US and EU airlines.

In this study, I will examine the impact of the EU-US Open Skies Agreement on the
total amount of passengers flying between the United Kingdom and the United States. As
the Agreement lifted regulations, airlines were free to start new flights between the two
countries. This should have brought increased travel, trade, and faster growth of the
industry. I have chosen to study flights connecting the United States and the United
Kingdom for two reasons. First, the UK and US had a much more restrictive agreement
before this treaty was signed. Second, as the British public voted to leave the European
3

Union in June 2016, this study could shine some light on what being a member of the EU
mean to the British aviation industry and even the economy as a whole.
Background
An Open Skies agreement is, in general, a treaty between two governments. It
concerns international flights rather than domestic. It eliminates government interference
in flight rights and price setting. Airlines no longer need to seek approval or bid for route
rights from either of the two governments when they wants to start a new flight between
two countries. The agreement is comparable to a visa waiver in international travel. If two
countries have agreements on visa-free travel, instead of having to obtain a visa before
travelling to a foreign country, a person can just pack up a bag and go to the other country.
Open Skies is a similar agreement, only it concerns airlines instead of individuals. An airline
can now fly to a foreign country without government approval from either side. Open Skies
requires governments to lift restrictions in many aspects. Aside from no restrictions on
route rights, there can also be no restrictions on the number of airlines operating, flight
capacity, frequency, or type and size of the aircraft used. This is intended to expand
passenger travel and trade by eliminating the regulation barrier on multiple aspects. Open
Skies agreements are aimed at creating a more competitive market that would provide
more benefits for consumers and foster faster growth.
According to the US Department of State, the United States currently has Open Skies
agreements with 120 countries, and flights to these countries account for 70% of all
international departures from the United States. The agreement that this research is
concerned with, the EU-US Open Skies Agreement, is the most significant major agreement
5
in recent years, as trans-Atlantic air travel is the largest international aviation market in
the world. In the US, there have been visible benefits of Open Skies as smaller cities in the
United States are getting more direct connections to Europe and Japan such as Cincinnati,
Salt Lake City, and Minneapolis as they gain international flights to destinations like Paris,
Frankfurt, Amsterdam, and Tokyo. The Bureau of Public Affairs states that new connections
between a US city and Europe generates up to $720 million annually in new economic
activity for a US city and its local region.
4
Another significant effect of Open Skies is the emergence of international medium-
haul low-cost airlines, such as EasyJet and Ryanair in Europe; Southwest, Jetblue, and
WestJet in North American; and Air Asia, Jetstar, and Scoot in East and Southeast Asia.
These airlines charge extremely low fares enabled by cost cuts from reduced staff and
services and from using secondary airports with lower landing fees. Low cost carriers have
been a major source of competition for the industry. These airlines have taken up
significant market share and have severely threatened the dominance of legacy carriers.
With newer, more efficient planes such as the Boeing 787 and Airbus A350, long-haul low
cost airlines became possible. Trans-Atlantic air travel is one of the first beneficiary with
WestJet and Norwegian Air Shuttle providing low fare flights between North America and
Europe. More importantly, low cost airlines enable a large portion of the population who
could never afford a plane ticket to be able to fly on an airplane, indirectly elevating the
living-standard of a considerable portion of the world’s population. This phenomenon is
especially vivid in developing countries such as Indonesia, India, and Vietnam. They are not
only essential to the competitiveness of the industry, but have also brought enormous

benefit for the market, and they would not exist without bilateral deregulation like Open
Skies, which created a free, competitive, and newbie-friendly market.
Question
Motivated by the controversial nature of airline deregulation in general and the
recent development of the United Kingdom’s referendum to leave the European Union, this
study aims to answer the question “how has the EU-US Open Skies Agreement impacted the
total number of passengers flying between the United Kingdom and the United States?”
Although there is abundant literature studying the effects of US domestic deregulation in
1978, there has been no empirical study done on impacts of the open skies agreement
between the EU and the US on passenger number, possibly due to its fairly recent
occurrence with insufficient data available until now. I chose to study passenger number
because there is reliable, precise, and accurate data on this value. It is also an excellent
indicator of the condition of the civil aviation industry and the economic condition of the
involved countries. It can properly demonstrate the economic impact of the EU-US Open
Skies Agreement not just on the industry, but on the economies of the EU and the US as a
whole. This study will help understand the direct effect of a bilateral open skies treaty on
transportation and trade between two countries.
Previous Literature
Airline deregulation in general has been a popular topic among scholars. Since,
however, international bilateral “open skies” treaty is a fairly recent phenomenon,
empirical studies on this subject have been almost non-existent. The vast majority of the
7
studies are limited to a domestic scope. Despite this shortcoming, some studies on the US
airline deregulation in 1978 offers backgrounds and methods for this research.
One of the earlier and more comprehensive studies on deregulation’s effect on the
industry and passengers is “U.S. Airline Deregulation: Its Effects on Passengers, Capital, and
Labor.” (Moore 1986) The paper analyzes the effects of deregulation on passengers, both
business and leisure/personal, and on airlines’ capital and labor. Moore compares the
number of carriers, fare changes, capacity, passenger number and departure number
changes in a number of sample city pairs in each category of the domestic airline market
before and after deregulation. A regression analysis of fares is done on distance, major
cities, and the number of carriers in each sample route of year 1976 and 1983 to determine
which factor influenced fares more before and after deregulation. Moore finds that at the
point of available data, five years after deregulation, the effects appear to be “mainly
beneficial,” more so for long haul flights than short haul ones. Long haul flight airfare has
decreased considerably while short haul flights saw some increases in fare from smaller
towns. A number of smaller towns lost service, while some have gained. More people are
travelling on discounted fares. In terms of capital and labor, Moore finds that stock values
have gone up, more so for newly founded airlines than legacy ones, while total employment
in the industry has grown. Overall, Moore concludes that deregulation has made air travel
available to the greater masses and benefited passengers of lower and moderate income.
Moore’s paper is the basis of the methods for this research. Although Moore does not use
panel data, the characteristics and data he uses in his comparisons and analysis gives
insight to the basic appropriate method to evaluating the effects of airline deregulation.
8
Labor is an important part of cost savings in the industry, as it gives an insight on
the operation efficiency of airlines as they are able to freely adjust their route structures to
profit maximize after deregulation. A study that focuses on impact of deregulation on
airline cost saving, done by Baltagi, Griffin, and Rich (1995), analyzes the changes in cost in
the US airline industry before and after deregulation, using a panel data set of airlines. The
paper examines industry trends in load factor, wages, and technological advances. It
analyzes the role of deregulation in supporting technical change. The study concludes that
deregulation has had a ‘pervasive’ effect on technical change and costs. The slow increase
in load factor and adoption of new aircraft is the cause of slow technical growth.
Meanwhile, 9.3% of cost saving for trunk airlines and 19.9% of that of regional airlines are
attributable to deregulation. The savings mainly come from higher load factor, reduced
union wage rates, faster output growth via lower fares, and a more efficient route structure
thanks to the hub-and-spoke system. Baltagi et al’s study gives the foundation of
understanding the deregulation’s role in increasing the operation efficiency of the industry,
as hub-and-spoke system enabled great cost-cuts and increased revenues for both
passenger and cargo transportation, which will affect the two principal factors considered
in this study: passenger number and cargo tonnage.
Theory on market structure and contestability is very relevant to the study on the
impact of airline deregulation. In the book, Contestable Markets and The Theory of Industry
Structure by Baumol, Panzar, and Willig published in 1982, the authors propose the theory
that if there is no cost to potential competitors entering or exiting the market, or ‘perfectly
contestable,’ the firms will establish a price configuration that maximizes market welfare.
Baumol, Panzar, and Willig state that “it is highly possible that air travel provides a real
9
example of contestable market”. Perfect contestability was proposed by Baumol and Bailey
as an alternative ideal for perfect competition. The theory suggests that in most industries
since small firms are almost always impractical and cannot survive due to inefficiency and
economics of scale, perfect competition is almost impossible to approximate for most
industries. However, perfect contestability suggests that an industry, even if it is
oligopolistic or monopolistic, as long as it maintains freedom of entry and exit, is still ideal,
because the absence of the entry barrier will prevent monopolists from making positive
profit and keep the equilibrium at optimal with maximum market welfare. For this to work,
there also cannot be sunk cost to enter or exit. Therefore, in theory, the police of this
market is potential rather than actual competition. In Baumol and Bailey’s paper
“Deregulation and the Theory of Contestable Markets” in 1984, the authors argue that the
airline market provides a “close approximation” to contestability. Under the Airline
Deregulation Act of 1978, the CAB can no longer limit new airlines to enter the industry,
while the main capital of an airline, the airplanes, can be easily moved from markets to
markets, thus mobile capital and small sunk cost makes this industry a close approximation
of contestability, even when there is only one firm operating a route.
This theory of the airline market is tested by Morrison and Winston’s paper
“Empirical Implications and Tests of the Contestability Hypothesis” in 1987. If the airline
market is perfectly contestable, there should be no change in welfare in markets with at
least one potential competitor. The paper defines ‘potential’ competitor as an airline that
already operates flights at point A or B but does not fly between point A and B. Morrison
and Winston tests 769 randomly selected routes, each with at least one potential
competitor. The result shows that none of the 769 routes have zero welfare change and
10
thus the airline market is not perfectly contestable. However, the airline market does prove
to be imperfectly contestable, where an increase in number of actual and potential
competitors reduces the differences between the optimal fare and actual fare.
There are some non-empirical papers written around the time when the EU-US
Open Skies Agreement took effect, discussing the projected impact of the agreement. One
paper by Eugene Alford and Richard Champley of the US Department of Commerce’s
International Trade Administration predicts the benefits of the agreement. The paper
demonstrates the possibility of airport growth as a result of growing passenger number
and cargo flow, which are variables that this study is trying to prove.
Model and Method
As stated above, the goal of this study is to understand how the Open Skies
Agreement of 2007 impacted the number of passengers flying between the UK and the US.
To determine the size of this impact, however, I cannot merely run a regression of
passenger numbers on a dummy for the open skies agreement and other covariates. the
coefficient would pick up changes in passenger numbers due to the Great Recession, a
period of extreme economic crisis that affected the US and the EU at around the same time
as the open skies agreement was implemented. This type of regression would assign to the
open skies coefficient the average change in passenger number from before the agreement
to after, regardless of whether it was the open skies agreement that caused that change.
Instead, to get an accurate estimate of the impact of the open skies agreement, I turn
to a difference-in-differences empirical approach. This approach allows me to compare the
change in the passenger numbers between the US and the UK (which the open skies
11
agreement should affect) to the change in the passenger numbers between a comparison
group (which ideally should be affected by all other important variables except the open
skies agreement). This approach, assuming the comparison group is chosen well, should
result in an unbiased estimate of the impact of the agreement.
In the main analysis of this paper, I have chosen as my comparison group all flights
that both originate and arrive within the UK. These UK domestic flights are a useful
comparison group because they are subject to similar market forces that influence
international flights between the UK and the US, but not the Open Skies Agreement. This
means that by differencing out the impact of the open skies agreement on the international
flights from the impact on the UK domestic flights, I should be able to obtain an unbiased
estimate.
In order to check for robustness, I have included three other control groups. To this
end, this study uses the following basic regression model:
Y=β0+β1*open_skies+𝛿+β2*GDP_UK+β3*GDP_US+β4*control+β5*interaction
(control*open_skies) +β6*Exchange_rate+β7*oil_price
Y represents the dependent variables including passenger number between each London
airport and each city in the United States, between London Heathrow and each city in the
United States, and all UK airports and all US airports. Regressions were run for each
dependent variable. Data for the all variables are collected annually from 2000 to 2014. 𝛿
represents individual flight fixed effect. Open skies will be a binary variable that takes on 0
before the agreement took effect in 2008 and 1 afterwards. GDP of the US and the UK will
be part of the control variables.
12
In order to more accurately record the effects of Open Skies while taking the 2008
Financial Crisis into account, this study employs four control groups that concern flights
between UK and areas that are not affected by the EU-US Open Skies Agreement but are
affected by the 2008 Financial Crisis. These four control groups are total passengers of UK
domestic flights, passenger number for each specific UK domestic flight, passenger number
of flights between UK and Beijing, and passenger number of flights between UK and Japan
(Tokyo, Osaka, Nagoya). To employ the control groups, difference-in-differences
regressions are run with passenger numbers of UK-US flights against the passenger
numbers of flights in the control groups. The control dummy variables take on the value of
1 if a sample is in a specific control group. There is also an interaction term assigned to
each control group, with interaction=control*open_skies, which takes on the value of 1 if a
sample is in a control group and is dated after 2008. The experiment group is also given a
dummy variable and an interaction term.
Data
Each data point of the dataset used for this study represents the annual passenger
number of a specific flight in one year. Data of annual passenger number of all flights used
for this research, including flights between the UK and the US, Japan, China, and domestic
UK flights are collected from the Civil Aviation Authority of the United Kingdom. The
annual GDP of the United States, United Kingdom, Japan, and the People’s Republic of China
are collected from the International Monetary Fund’s 2016 dataset. GDP data is collected in
2016 current price in US Dollars. Price of jet fuel and Brent crude oil are collected annually
from the US Energy Information Administration. Average annual exchange rates are
collected for rates between British Pounds and US Dollars, Japanese Yen, Chinese yuan
13
from the US Foreign Exchange Service. The dataset encompasses all transatlantic flights
between the United Kingdom and the United States, and all domestic flights within the
United Kingdom as provided by the Civil Aviation Authority of the United Kingdom. All data
dates from 2000 to 2014.

Results
Difference-in-differences regressions with all control groups yielded statistically
significant results at the 1% level. This proves that the EU-US Open Skies Agreement
positively affected passenger numbers between the UK and the US by a large scale. When
regressing the passenger number between London Heathrow Airport and US cities against
that of UK domestic flights, the coefficient for the UK-US interaction term is 66,919.49
while the coefficient for the total UK domestic interaction is -2,324,355, both coefficients
are significant. This means after Open Skies, UK domestic flights were hit by the financial
crisis and experienced a decline in the number of passengers. Meanwhile, flights between
TABLE 1: Data Summary
14
London Heathrow and US cities, however, grew by 66,919.49, which means that the
number of passengers travelling between London Heathrow and each US city has increased
by an average of 66,919 people annually. Relative to UK domestic flights, ridership of flights
between the UK and the US has increased by 2.3 million. The average passenger flow
between London Heathrow and each US city is 631,339, while the max is about 3 million.
An average annual increase of 66919 is about 10% growth in the average passenger
number between the UK and the US, a considerable growth for the market. The joint-
significance of the sum of the coefficients for Open Skies and the interaction term is
significant at the 10% level. This result is similar to Moore’s evaluation of the effects of the
US domestic deregulation in 1978, where he noted an increase in total passenger number,
especially in discounted fares. It needs to be noted that many US airlines moved their
operations from London Gatwick Airport to London Heathrow Airport after Open Skies
took effect in 2008 which could skew the result.

The two control groups for robustness checks, Japan and China, also yielded
significant results. In the regression with control group of flights between the United
Kingdom and Japan, the coefficient for the interaction term of the Japanese control group
has a value of -393,101, significant at the 1% level meaning passenger number travelling
between the UK and Japan has decreased by 393,101 people when compared to passenger
number travelling between the UK and the US. This number accounts for about 40% of all
passenger traffic between the UK and Japan in 2008. While air travel is experiencing a
decline due to the 2008 Financial Crisis, the new deregulation protected the growth of

passenger number on flights between the UK and the US relative to flights between the UK
and Japan. Open Skies cushioned the shock that the Financial Crisis had on UK-US air travel.

TABLE 3: Regression of total UK-US w/ control UK-Japan

A statistically significant, albeit negative result came from the regression with the
control group of flights between the UK and China. The regression shows that flights to
China are actually growing faster relative to flights between to the US, with the statistically
significant coefficient of the interaction term being 145,050. The reason for this could be
that China is a growing market and flight capacity has been expanding since the late 2000s,
with new flights inaugurated and frequencies increased. Air China added more flights
between Beijing and London Heathrow while starting a new flight between Beijing and
London Gatwick. During this time, it also started replacing its Airbus A330s used on these
routes with new Boeing 777s which have much greater capacity. It makes sense that China
as an emerging and not-yet fully open market would experience higher-than-average
growth. At the same time as a relatively closed economy, China is not hit as severely by the

All of the above regressions have a consistent adjusted R-square value of 0.98 as
98% of the variations of passenger number between the UK and the US can be explained by
the independent variables.

Conclusion
This finding of an increase of passenger flow between the United Kingdom and the
United States relative to the UK Domestic and UK-Japan control groups in the face of the
2008 Financial Crisis suggests a considerable positive effect of the EU-US Open Skies
Agreement. While this study only shows the impact of Open Skies on flights between the
UK and the US, this agreement would likely bring similar growth and benefits for the
entirety of the North Atlantic air travel market between the United States and the rest of
the European Union, not only in terms of passenger numbers, but also cargo tonnage. The
results of this study demonstrate that a deregulated and liberalized airline industry with
less government regulation or restriction would lead to tremendous growth and encourage
greater flow of people. It would contribute to the economic growth of both parties of the

bilateral agreement. This agreement enables a freer flow of people and goods between the
United States and Europe.
Brexit
In June 2016, 51.9% of voters in the UK voted to leave the European Union in the UK
EU Membership Referendum. If the United Kingdom were to leave the European Union, the
EU-US Open Skies Agreement would no longer apply to the UK. The agreement regulating
air traffic before Open Skies came into effect was the Bermuda II, a highly restrictive
agreement by today’s standard, which also contrasted the principles of deregulated airline
markets. Without Open Skies, a separate negotiation would have to take place and a new
agreement would have to be signed to govern air travel between the United Kingdom and
the United States.
This study has proven a 10% increase of passengers travelling between London and
the US alone. If the United Kingdom were to exit the European Union, it is certain that there
will be considerable negative impact on air travel between the UK and the US. The damage
would be even greater to the British airline industry considering flights to continental
Europe. A large number of British airlines currently rely on the UK’s European Union
membership to be able to operate within continental Europe. One example is EasyJet,
which is the second largest airline in Europe in terms of passengers carried. Despite being a
British airline, it has significant presence in the continent where it operates flights between
cities outside the UK, with Milan being the airline’s second largest hub. These are known as
eighth freedom traffic rights, which is currently only possible within the European single
aviation market. If the UK were to leave the EU, EasyJet can no longer operate within the
21
continent, and its flight between the UK and the continent would face restrictions. Civil
aviation is one of the most basic infrastructures of a country’s economy today. It is the
prerequisite for the free flow of people and goods. It is especially important for the United
Kingdom as its economy heavily relies on the financial industry. A more regulated and
restrictive legal framework would not only restrict growth of air travel and cargo flow, but
also hinder economic growth of a country as a whole. With protectionist, anti-free trade
right-wing politicians such as Nigel Farage, Marine La Pen, Geert Wilders, and Donald
Trump taking on ever more popularity in both continents, it is very uncertain whether a
new agreement will be a liberalizing one. It would certainly be a step backward, in practice
and in principle, if air travel between two of the world’s most developed countries was to
become more restrictive after liberalization.
