The restaurant will close for 12 weeks next year as it undergoes a makeover, before reopening in July, when it will boast a new bar along with the creation of semi-private dining areas.
Plane Food opened in Heathrow back in 2008, costing £2.5m to build, and today serves more than 800 customers with à la carte dining, 25-minute Express menus and “on-board picnics” a day.
It was chef Gordon Ramsay's first airport restaurant - in 2013 he announced plans to take the concept to airports across the US too.
In an interview with City A.M. last month, Ramsay discussed the prospects of Brexit for the UK.
"Brexit is going to give every country the freedom to become a little powerhouse, individually," he said.
"It will make countries reinvest locally. It may seem tempestuous to begin with, the jeopardy of not being part of the European safety-net. But it will be an advantage; that’s as a chef, as a businessman and as a customer.”
Today 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.”
