Flying from London Gatwick
Gatwick is London's leisure-leaning airport — the home of British Airways' short-haul leisure operation, easyJet's largest UK base and a long lineup of TUI and Norwegian holiday flights. South and central London passengers reach it via the Gatwick Express or Thameslink. The mix is broader than Heathrow on European leisure routes, often cheaper, and you'll see the same destination served three or four times a day across competing airlines — useful when one carrier delays.
