Major UK airports: a reference list

What are the UK's main airports?

The busiest UK airports include London Heathrow (LHR), London Gatwick (LGW), London Stansted (STN), London Luton (LTN), London City (LCY), Manchester (MAN), Birmingham (BHX), Edinburgh (EDI), Glasgow (GLA), Bristol (BRS) and Belfast International (BFS) — between them covering most domestic and international routes.

This is a reference list of names and codes, not a live arrivals/departures board — that kind of data needs a paid flight-data feed, which this site does not use.
