All-premium class airline, Eos, is insisting it is still on schedule to launch flights at the end of September between London Stansted and New York JFK.
Eos has recently received its 'show cause order' from the US Transportation Department, tentatively approving the airline's certification, and is currently waiting for the FAA approval that will allow it to start flying.
A spokeswoman said this would be achieved in the next week or so and flights will launch at the end of September as planned.
The privately-owned airline is promising each passenger 21 square feet in space by offering only 48 seats in a Boeing 757 aircraft which can seat up to 200.
David Spurlock, founder and CEO of Eos and former director of strategic development for British Airways, said: "We've designed every aspect of the Eos experience specifically with the business traveller in mind. We recognise that time in the air could be better spent relaxing and reviving for an upcoming business trip or to accomplish work along the way in privacy."
Each ergonomically designed seat, with a privacy shell, is over 21 inches wide when upright and 24 inches wide when fully reclined to a six foot five-inch bed.
All 24 window seats have a direct path to the aisle.
Founded in March 2003, Eos is named after the Greek goddess of the Dawn.
The company has raised $87 million in equity and approximately $100 million in lease financing.
