The most popular airlines from Gatwick include easyjet, British Airways, Norwegian Air, Thomas Cook, TUI and Ryanair. TUI and easyjet flights come in and out of the North Terminal, while British Airways, Norwegian Air, Thomas Cook and Ryanair all use the South Terminal.
The majority of Gatwick flights operate out of South Terminal, including budget airlines Ryanair and easyjet, though British Airways, Emirates and other international airlines use the North Terminal. You can easily travel between the two using the free, 24-hour airport shuttle train, running every few minutes.
North Terminal now houses all of easyJet's flights as part of ongoing work to improve the services at Gatwick. Gatwick South Terminal deals with the majority of the airport's traffic and is the original terminal of the airport.
The two passenger terminals at Gatwick Airport are a long way apart; it is not possible to walk between them. There is a free monorail train service that shuttles between the two terminals every 2 or 3 minutes making journeys between the two terminals a breeze, even with luggage.
To find out your flight's terminal, you generally just need to check your airline confirmation or flight itinerary. This can be found either in your email confirmation, or on the airline's website closer to the day of departure.
There are two terminals at Gatwick, North and South. South terminal is where the railway station is. There is an automatic shuttle train between the two terminals. So the North terminal needs an extra 5–10 minutes to get from the railway station to check-in, and the same time in the opposite direction.
Choosing the best airport in London depends on various factors, such as flight availability, airline preferences, and transportation options. If convenience and proximity to downtown London are your priorities, Heathrow might be the better choice due to its extensive global connectivity and luxurious lounges.
