Masterchef judges John Torode and Gregg Wallace have been appointed the official taste buds of London Heathrow.
The restaurateurs have challenged the airport's food and beverage experts to introduce healthier menu choices across the terminals and to create a platform to champion British culinary talent.
They set the six-month challenge after being given access to all areas of the airport to sip, sample and savour dishes from LHR's 73 restaurants and bars.
Their experiences are also being used to inform Heathrow's first-ever food guide. Food On The Fly will provide passengers with an overview of the varied dining options available in the airport.
Each year, some 26 million orders are placed at Heathrow's restaurants and bars.
Wallace said: "Food is our first love and at the heart of everything we do, so we were delighted when we were invited to take part in this eating challenge - and to contribute to the guide.
"We were blown away by the range on offer to hungry passengers at Heathrow. Catering for such a huge spectrum of passengers is truly a herculean task."
Ten thousand copies of Food On The Fly will be published and handed out to passengers to mark the summer getaway with a digital version available to download from heathrowairport.com from July.
Ben Crowley, head of food and beverage at Heathrow, said: "Heathrow's food and drink offering is designed specifically with travellers in mind - from people passing through several time zones in a very short space of time to those needing a meal in minutes.
"We are hugely excited about responding to the challenge John and Gregg have set and at bringing a new dimension to Heathrow food and beverage offering.
"It's often hard to show passengers - especially those in a hurry - the full extent of our offering so it's very exciting to be able to work with John and Gregg to produce this really comprehensive guide. "
