British Airways will this week serve traditional fish and chips on some short-haul flights.
Passengers on services between Heathrow and Athens, Larnaca, Istanbul, Sofia, St Petersburg and Kiev will be the first to taste the latest addition to the airline's menu.
If it proves popular, fish and chips will be extended onto more BA short-haul routes.
The meal is served in an environmentally friendly box and will come with vinegar, ketchup and tartare sauce.
Sinead Ferguson, BA's menu development manager, said: "What better meal to see onboard a summer flight than the traditional British fish supper? We know our customers love comfort food and expect it to be done well when they fly with us.
"Naturally, we went for sustainable cod and we've worked hard with Green Gourmet to make the perfect chip, which in the past has been a challenge to produce at 35,000 feet.
"We think our secret recipe delivers just the right crunch and hopefully our customers will agree. If so, we plan to roll out the fish supper on our longest short-haul flights this summer."
BA's catering team developed the meal alongside food innovation specialists Green Gourmet.
