Gatwick’s South Terminal will reopen on 27 March following a two-year closure due to the pandemic.
It will be the base for British Airways’ long-haul flights and its new EuroFlyer short-haul operation, due to launch on 29 March.
BA sister airline Vueling, Aer Lingus, Ryanair, Turkish Airlines, TAP Portugal and Eastern Airways will also move back from the North Terminal to the South Terminal.
EasyJet will operate from both the North and South Terminals after taking 230 weekly take off and landing slots on loan from BA to expand its summer schedule.
