Some 16.8 million passengers passed through Heathrow Airport in London first three months of 2016, up 2.6 per cent.

At the same time, Garuda Indonesia has become the latest airline to move its London operations from Gatwick to Heathrow – boosting British businesses with increased ties to a fast-growing economy.

Heathrow recoded strong financial performance for the period, with revenue up 3.2 per cent to £642 million and EBITDA up 7.3 per cent to £367 million.

A statement from the airport argued the rise reflected lower costs and better value.

John Holland-Kaye, chief executive, Heathrow, said: “It’s been a fantastic start to 2016 and Heathrow is performing strongly on all fronts.

“Our colleagues are delivering excellent value for our passengers - better service at a lower cost.

“At a time of uncertainty about Britain’s place in the world, families and businesses are counting on the prime minister to secure Britain’s long term future. 

“An expanded Heathrow will be an economic powerhouse, a global symbol of a confident, outward looking Britain.

“Let’s make it happen.”
