A new report published by Heathrow Airport shows that a lack of capacity at the airport is costing the UK economy £14 billion a year in lost trade.
Further to that the report goes on to say that this figure could rise to £26 billion a year by 2030.
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.
The Davies Commission is expected to present an interim report to the government by the end of 2013, with a full report due in the summer of 2015 - after the next general election.
Heathrow's report, One hub or none, was prepared for the airport by consultants Frontier Economics. It was commissioned to inform Heathrow's response to the Davies Commission but is not its formal submission.
"If anyone was still in doubt about the importance of aviation to the UK economy, today's report should lay those doubts to rest," Heathrow chief executive Colin Matthews said.
