Which terminal is wizz air at LGW? Wizz Air is based at London Gatwick Airport's South Terminal (LGW). My own flight with Wizz Air from Gatwick's South Terminal was reasonably easy and efficient, especially for a low-cost airline. Upon arriving at the terminal, the check-in process was smooth, though it’s always a good idea to arrive early to avoid long lines, as budget airlines tend to have busier counters. The abundance of dining and shopping options in the South Terminal made waiting for my flight more enjoyable. The trip was enjoyable and stress-free thanks to the experience at LGW's South Terminal and Wizz Air's effective service,especially given the airline’s affordability.
