Terminal Information – Departing

Both terminals at Gatwick have a wide range of shops, restaurants, bars and lounges. Double-check your terminal once you arrive at the airport. The train station is in the south terminal, so you will need to take the inter-terminal shuttle if you're departing from the north.

Terminal 5 is renowned for its designer shops and high-end restaurants. Enjoy a pre-flight meal at Gordon Ramsay's Plane Food, or browse shops like Paul Smith and Burberry. Terminal 3 also has a good range of places to eat and shop, whether you're in the mood for high-street fare or something higher end.
