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, under-
represented 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.
