American Express Global Business Travel has joined the campaign demanding a fundamental shake-up in how Heathrow is regulated and governed.

Heathrow Reimagined is demanding UK regulator the CAA conducts an urgent and fundamental review Heathrow for the benefit of consumers, businesses, and the UK economy.

Discussions are ongoing about potential solutions that won’t delay the UK government’s revived timetable for expansion amid what the campaign claims has been years of declining passenger experience and ageing infrastructure.

New regulatory reform options have been developed with insights from other international models, although Heathrow Reimagined says it is likely Heathrow will need a bespoke solution to be effective.

A spokesperson for Heathrow Reimagined, said: “Just last month, despite being the world’s most expensive airport, Heathrow yet again failed to rank inside the Top 20 Global Rankings by Skytrax.

“We urgently require a fundamental review by the CAA to understand what has gone wrong and to create a regulatory model that can deliver the Top 5 Hub airport Britain deserves.

“This support from Amex GBT is both a demonstration of the campaign’s continued momentum across the aviation, business and travel industries, and also another clear signal from the international community and customers of Heathrow that the time to act is now.”

Andrew Crawley, president at Amex GBT, added: “To deliver on its growth agenda, the UK requires a world class hub airport. For too long, the existing regulatory model has incentivised inefficient spend leaving businesses paying more for less.

“We look forward to working with Heathrow Reimagined to improve traveller experience and unlock the significant potential Heathrow presents for the global business travel community. Without action now, we risk prices rising for businesses for decades to come.”

As well as Amex GBT Heathrow Reimagined is supported by the Heathrow Airline Operators’ Committee (AOC), Advantage Travel Partnership, American Airlines, Arora Group, Board of Airline Representatives in the UK (BAR UK), Business Travel Association (BTA), International Air Transport Association (IATA), International Airlines Group (IAG), Virgin Atlantic and World Travel & Tourism Council (WTTC).
