About flying to London

London has more airport capacity than any other European city, and that shapes how you should shop for fares. Heathrow carries most long-haul traffic, while Gatwick, Stansted, Luton and City split short-haul and low-cost flying between them. The same journey can cost very different amounts depending on which airport a carrier uses.

For that reason, London is the clearest example of why tracking more than one airport pays off. If your onward plans work from any of them, watching two or three in parallel is usually worth more than shifting your travel dates.

Arriving at London Heathrow

Heathrow sits west of the city with Underground and express rail links to central London in 15–50 minutes depending on the service. Allow extra time for terminal transfers at Heathrow — moving between terminals is possible but not quick.
