Data Sources
The new econometric analysis undertaken by InterVISTAS
Consulting used three different datasets:
• US Department of Transport database 1B (DB1B).
DB1B provides data on the US domestic aviation
market. Traffic figures reflect the actual number of
passengers on a particular route, while average price
reflects the estimated average one-way travel price
paid (in USD).
• IATA’s Passenger Intelligence Service (PaxIS)
database. This database captures market data
through IATA’s Billing and Settlement Plan (BSP). It
provides traffic and travel price estimates for airportpair
routes around the world (e.g. JFK-LHR, CDGFRA).
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. Traffic figures reflect the
estimated number of passengers on a particular
airport-pair route, while average travel price reflects the
estimated average price paid (in GBP).
