To use Gatwick Fast Track, you must first purchase a pass, which is ideally done online in advance for a lower rate (starting at approximately £5 to £6). Once you arrive at either the North or South Terminal at London Gatwick Airport, you should look for the clearly marked "Fast Track" dedicated lane at the security entrance. Instead of joining the standard, often long security queue, you present your pre-booked digital or printed QR code to the gate agent or scan it at the automated turnstiles. This allows you to bypass the bulk of the crowd and enter an express screening lane. It is important to note that Fast Track only speeds up the time spent waiting in line; the security screening process itself—including liquid and laptop checks—is exactly the same. Fast Track is also available for Passport Control (Arrivals) for a higher fee (around £15), which is particularly useful for those traveling without checked bags who want to exit the airport quickly.
