The Key Routes section analyses punctuality on 50 of the busiest routes by scheduled carriers from the five London Airports; Heathrow, Gatwick, Stansted, Luton and London City. More than half of all flights to and from London Airports (55% in 2007) operated on one of these routes. Data is available for full years, and for the current year to date.
