Why London is one of the best cities for cheap flights
London has five airports served by dozens of budget and full-service airlines, which means genuine competition on almost every route. Ryanair dominates Stansted, easyJet is strong at Gatwick and Luton, and British Airways adds competition on popular routes like Dublin and Amsterdam. That rivalry keeps prices low. The key is knowing which airport serves your destination — Stansted is 45 minutes from central London by train, Gatwick 30 minutes. Factor that in when comparing prices.
