For departures from London Gatwick (LGW), the recommended check-in time depends on your destination and your airline's specific requirements. For international long-haul flights, you should aim to be at the airport at least 3 hours before your scheduled departure. For European and domestic UK flights, 2 hours is generally sufficient. It is important to check whether your flight departs from the North or South Terminal, as they are connected by a shuttle but require separate travel time. In 2026, many airlines at Gatwick (especially easyJet, British Airways, and TUI) utilize "Bag Drop" kiosks where you must scan your own boarding pass and tag your own luggage; these kiosks typically close strictly 60 minutes before departure. If you have already checked in online and are traveling with carry-on only, you can head straight to security, but you should still allow at least 90 minutes to navigate the lines, which can be quite long during peak holiday periods. Gatwick also offers a "Premium Security" service for a fee, which can shave time off your journey. Always check your airline's app on the day of travel, as "check-in opening times" can vary based on operational needs at the terminal.
