US Department of Transport’s database 1B
(DB1B). DB1B provides data on the US domestic
aviation market. It is a very reliable source of data,
representing a 10% sample of origin-destination
passengers and air travel price for each airline on each
city-pair route (e.g. New York-Los Angeles). Quarterly
traffic and price data was taken for the period from
1994 Q1 to 2005 Q4 for the top 1000 city pair routes
(by traffic). Traffic figures reflect the actual number
of passengers on a particular route during the given
quarter, while average travel price reflects the estimated
average one-way price paid (in USD).
• IATA’s Passenger Intelligence Service (PaxIS)
database. This database captures market data
through IATA’s Billing and Settlement Plan (BSP) and
uses statistical estimates to address missing direct
sales, low cost carriers, charter flight operators, underrepresented
BSP markets, and non-BSP markets. It
provides traffic and price estimates for airport-pair
routes around the world (e.g. JFK-LHR, CDG-FRA).
However, data is only available from 2005 onwards.
• UK International Passenger Survey (IPS). The
IPS is a survey of passengers entering or leaving
the UK by air, sea or the Channel Tunnel. This report
exclusively used outbound to Western Europe leisure
air passenger traffic data from the IPS. Quarterly
traffic and price data was taken for the period from
2003 Q2 to 2006 Q2. Traffic figures reflect the
estimated number of passengers on a particular
airport-pair route during the given quarter, while
average price reflects the estimated average price
paid (in GBP).
