Determining your terminal at London Gatwick is primarily based on the airline you are flying with, and it is crucial to check your e-ticket as some airlines operate from both. In 2026, the North Terminal is the primary hub for easyJet (though some flight numbers 6300–6599 use the South), as well as TUI, Emirates, and Qatar Airways. The South Terminal is home to British Airways, Vueling, and most other international carriers like Norwegian and Ryanair. A simple way to verify is to check the Gatwick Airport website's "Which Terminal" tool by entering your flight number. Additionally, the Gatwick station is located at the South Terminal; if your flight departs from the North Terminal, you will need to take the free, 24-hour automated shuttle train, which takes about two minutes. Most airlines will also display the terminal prominently on their mobile apps once you check in. If you are flying with TUI, remember that "TOM" prefixed flights use North, while "BY" prefixed flights (operated by partners) typically use the South Terminal.
