Birmingham International Airport has called for a deal between the United States and the European Union to increase choice on transatlantic routes to benefit airports other than the UK's "usual suspects".
The tentative agreement between the EU and the US, to be ratified by European transport ministers at a meeting next month, would end restrictions on airlines, allowing them to decide on routes and service frequencies.
BIA's head of corporate affairs, John Morris, welcomed the deal but said that the benefits must be shared throughout the UK and not just by the London hubs.
He said: "The long-awaited agreement is good news and must now be reviewed by EU transport ministers, who meet in December.
"An ideal solution would scrap remaining restrictions on service and routes between European and US destinations and would give airlines the choice on frequency of service, the routes operated, or the aircraft used.
"We want to be assured that the UK regions have the opportunity to benefit economically from the new legislation and that lawmakers do not become fixated on airports in the South-east, or, indeed, the large US metropolitan airports."
BIA is consulting on a expansion plan which will allow for a predicted tripling of passengers over the next 25 years.
The plans include a second runway and an extension to the current airstrip, which will allow long-haul flights to operate between Birmingham and the US west coast and the Far East for the first time.
"More and more people want the option of point-topoint journeys, and research has shown that such links can massively improve the regional economies that they serve," said Mr Morris.
"At the moment over 50 per cent of people who live near to BIA make unnecessary journeys to other airports because Birmingham does not have the capability to offer certain long-haul flights, such as those to the western USA.
"Our runway extension, plus liberalisation of the market, could sweep away that barrier."
