London City Airport is launching a multimillion refit of its terminal building early next year.
The project, which is due to be completed next year, will expand the departure area and also increase the number of security channels.
The move has been prompted by the number of passengers booking online and skipping check-in and going straight to security.
Melanie Burnley, Director Terminal Services at London City Airport, said: “We are introducing additional security lanes to respond to the change in passenger behaviour.
“With a greater use of online check-in and less use of traditional check-in desks, more passengers are heading straight to security upon arrival at the airport.”
Research has already commenced on establishing how many new lanes will be needed ahead of the work starting.
The announcement comes just over two weeks ahead of British Airways’ launch of its all-business service to New York on September 29, which it is marketing as 15 minutes from check-in to take-off.
BA will initially be flying one 32-seat Airbus A319 daily via Shannon Airport where passengers will be cleared for US security, arriving at JFK as a domestic flight.
The aircraft will be fitted with an enhanced Club World product, in a 2-2 configuration, with all seats facing forward.
