Gatwick has announced that easyJet and British Airways will operate out of dedicated terminals at the airport from next year.
EasyJet will consolidate its operations at Gatwick’s North Terminal and no longer operate out of Gatwick South from November 2016.
BA will move all its operations to the airport’s South Terminal.
Gatwick promised the North Terminal would be “completely transformed” with new check-in, security and departure lounge areas, new retail space and refurbished arrivals area.
The airport has already upgraded facilities at its South Terminal.
EasyJet chief executive Carolyn McCall (pictured) said: “As our largest base, Gatwick is of huge importance to easyJet.
“Moving to one terminal creates the opportunity for easyJet and Gatwick to plan and deliver an improved experience for our passengers.”
She added: “We plan to continue to grow at Gatwick through increasing destinations, further improving our schedule and deploying larger aircraft.”
EasyJet increased its capacity from Gatwick by up to 16% year on year last summer and plans a further increase this summer.
BA director of strategy Lynne Embleton said: “The South Terminal has recently received significant investment to its security area and departure lounge and we will be working with Gatwick to provide customers with a new check-in area and lounge.”
Gatwick South Terminal has direct access to trains to and from London Victoria and the rail station is to undergo a £120 million upgrade.
Stewart Wingate, Gatwick’s chief executive, said: “This is a major milestone on our journey to become one of the world’s most efficient airports.”
Gatwick, along with Heathrow, is awaiting an Airports Commission report on whether it will be selected as the site for a new runway.
Wingate claimed: “We will build the world’s most efficient two-runway airport if we win the right to expand.”
EasyJet and BA are the biggest carriers at Gatwick.
