Why an A–Z index?
Most travellers know an airport by its IATA code before they know the full name. JFK, LAX, LHR, SIN. The A to Z directory is for that audience. If you have a code in hand and want to see who flies there, jump to the right letter and click through to the airport page. Each profile lists the airport's name, ICAO code, location, time zone, and the destinations and operators on file, with cross-links to country and state pages for broader context.
