The return to full service will offer guests a new dining experience, where each course is served to customers individually.
British Airways will start serving hot soups and warm desserts, with the redesigned menu featuring food from local British producers.
The airline is also reintroducing its express service on evening flights, where customers will be able to request a one-tray service so they can eat and then sleep.
Sajida Ismail, British Airways’ head of onboard experience, said: "It’s incredibly important that when we brought our full service back, it exceeded our customers’ expectations.
"We have taken time to ensure that we are offering a premium brasserie-style dining experience that not only tastes good, but one that our crew feel confident in delivering."
The carrier is also continuing to roll out its newest business class seat, Club Suite, across its Boeing 777 fleet.
