Abstract:
Airline alliances have been dominating the air transport industry since the
1990s and by now the four strategic alliances, in which almost all of the major
airlines participate, control the 56% of the world RPK.
The thesis examines the airline alliance phenomenon in its entirety and more
specifically, it examines the reasons and circumstances that have led to the
formulation of these alliances and the impact these alliances have had on the
participating airlines.
A key parameter airlines use to assess their own performance and that of
alliances is traffic. Thus, the present research examines alliances impact on
the traffic of the allied partners by different types of routes (hub-hub, hub-non
hub and non hub-non hub), different types of cooperation (FFP, code share,
strategic alliance without and with antitrust immunity) and by the length of the
route. In addition, the thesis analyses which alliance groupings, which type of
airline and which geographical area have produced the best results from the
alliances.
To achieve these objectives, the thesis is divided into a theoretical and an
empirical part. The theoretical approach starts with an industry alliance
overview and then moves to the presentation of airline alliances, by
discussing the reasons that have led to their establishment, the evolution of
the regulatory framework around which airline alliances have developed, the
definition of airline alliances, the different forms they have taken, their
advantages and disadvantages; and finally, the past and current alliance
groups.
The empirical part focuses on the alliance traffic and analyses it around two
different axes. The first consists of a survey in which the airlines participating
in alliances were asked to assess their alliance participation and to quantify
the impact of alliances on several parameters of their operation and
performance and more specifically, on their passenger traffic. The second
analyzes this impact on the basis of an econometric model that seeks to
determine and measure any positive impact on traffic volume generated by
alliances. The findings indicate that airlines are satisfied from their alliance experience
as they have helped them achieve the main purpose for which they have
resorted to alliances, that is to secure increased network coverage with little
capital investment. Both the survey and the econometric model indicate that
airline alliances have led to an increase in passenger traffic amounting to
10%. According to the survey, this traffic increase is mainly registered on hubhub
routes while the econometric model indicates that this increase is evenly
distributed on hub-hub and hub-non hub routes. The benefits result mostly
from the marketing cooperation and appear within one or two years from the
establishment of the alliance. Alliances may bring about cost reduction, but
this depends on the level of integration among the partners. Almost all
participants agree that alliances are the final stage of airline cooperation and
that there will be no or very few mergers.
