Billions lost because 'Heathrow airport not big enough'
A lack of capacity at Heathrow is costing the UK economy £14bn a year in lost trade, according to a report published by the airport.
The report, called "One hub or none", says that figure could rise to £26bn a year by 2030, as Heathrow bosses are keen to see a third runway built at the west London airport, but the government has ruled it out for the time being.
The government has asked a commission headed by Sir Howard Davies to advise on future UK airport capacity needs.
Heathrow chief executive Colin Matthews said it was time to look at the options, although none are easy.
