US Airways is launching a non-stop daily service between Philadephia and Edinburgh next summer.
The route will run from May 23 to October 1 and will be operated by a 176-seat dual class Boeing 757.
It is the airline's first ever non-stop service to the Scottish capital.
Flight 784 will depart Philadelphia International Airport at 2050, and arrive in Edinburgh at 0840 the next day. Return service 785 will leave Edinburgh at 1050 and land in Philadephia at 1335.
Andrew Nocella, the carrier's senior vice president, marketing and planning, said: "US Airways' new non-stop service will offer travellers from both sides of the Atlantic Ocean a direct connection between the unique, historic cities of Edinburgh and Philadelphia.
"This is our first opportunity to serve Scotland's capital from our Philadelphia gateway, and we look forward to strengthening our ability to help customers explore the British Isles."
When the new route opens, US Airways will operate 472 weekday departures and serve 118 destinations.
The service will likely be an American Airlines route by next summer, should the US Airways / AA merger complete after it got back on track last week (see news, November 13).
In September, United Airlines announced that it will fly a summer seasonal service between Edinburgh and Chicago next year (see news, September 12).
