Changes will be introduced over the coming months and include new furnishings, enhanced service and, from February 1, an improved dining experience.
It will feature a third main meal option and a more substantial hot second meal later in the flight.
BA will also be adding new amenity kits, quilts and pillows.
“This latest tranche of our £6.5billion investment is set to improve World Traveller Plus and customers will see a real change to the cabin,” says Carolina Martinoli, the airline’s Director of Brand and Customer Experience.
“In February the new menus will launch, followed in the spring by the introduction of new amenity kits, quilts and pillows for added comfort and a touch of luxury.”
A new World Traveller Plus seat was unveiled last year that features a 50% larger entertainment screen and adjustable leg, foot and head rests. The seat will be installed on BA’s A350 aircraft when they are delivered later this year.
The airline is expected to reveal an overhaul to its Club World business class seating and service later this year.
