Heathrow said increased capacity is now more important following Brexit to boost trade links with other countries globally.
“Now Britain needs a positive post-Brexit plan and only Heathrow expansion will help Britain to be one of the world’s leading trading nations – connecting all of Britain to global growth,” said CEO John Holland-Kaye (pictured).
“Heathrow has a new plan for expansion, allowing the Prime Minister to make the right choice in the national interest.”
Following the publication of its first half-year results the airport said it expects some short-term uncertainty following the EU referendum result but its “resilience” puts it in a “compelling market position”.
Heathrow saw revenue rise 1 per cent to £1.3 million and adjusted EBITDA up 4.4 per cent to £781 million.
Passenger numbers were up slightly (0.6%) to 35.7 million.
Heathrow added it has met or exceeded all conditions in Airports Commission’s recommendation for expansion which also has overwhelming parliamentary support.
Holland-Kaye said: “Heathrow has been named the best major airport in Europe for the third time and I am very proud of the work our colleagues do every day while giving better value to passengers.
“As the UK’s biggest port, we are supporting businesses from every corner of Britain to get their products to global markets, with cargo volumes up by almost 2%.”
