Gordon Ramsay Group has signed a 10-year contract with Heathrow Airport to retain its Plane Food site at Terminal Five.
Plane Food opened in the departure lounge in 2008 and offers all-day dining both before and during flight.
It serves 800 customers a day with à la carte dining, 25-minute express menus and on-board picnics.
As part of the renewed agreement, the group will develop further on the picnic concept, which it says could generate over £70m in revenue.
Stuart Gillies, CEO of Gordon Ramsay Group, said: "We are excited to continue our partnership with Heathrow, combining our expertise in dining and travel. Plane Food has provided a very good return on investment for the group and also, as the UK's hub airport, Heathrow has been the perfect location for us to showcase our offering to a discerning international audience of travellers.
"As we continue to expand globally, our work with an organisation that plays such a central role in connecting London to the rest of the world is extremely fitting."
Chris Annetts, retail director for Heathrow, said: "Since its opening in 2008, Gordon Ramsay's Plane Food has become a cornerstone of the Terminal 5 experience for so many of our passengers We are proud to be continuing our partnership with the Gordon Ramsay Group and are excited about the state of the art dining concept the team are planning to unveil next summer."
Gordon Ramsay Group operates 29 restaurants globally, with a total of six Michelin stars.
