American Airlines will move three of its London flights from Gatwick Airport to Heathrow Airport in the coming weeks as part of the “Open Skies” agreement between the United States (U.S.) and the European Union (EU) which takes effect March 30.

American previously announced that it will move one of its two daily round trips between Dallas/Fort Worth (DFW) and London Gatwick, as well as its daily round trip between Raleigh/Durham (RDU) and Gatwick, to London Heathrow Airport (LHR) on March 30.

In addition, American will be moving its second daily round trip between DFW and Gatwick to Heathrow on April 13. American recently obtained additional take-off and landing slots at Heathrow to make that move possible. This will result in the closure of American’s Gatwick operations after 26 years of service. All of American’s employees at Gatwick have been offered jobs at the airline’s other London locations.

“ We want to strengthen our competitive position within the new ‘Open Skies’ regime, so it makes sense to focus our efforts in London at Heathrow,” said Henry Joyner, American’s Senior Vice President – Planning. “These changes do not impact the total number of American flights to and from London. We’ll operate up to 18 daily departures to Heathrow this summer from seven U.S. airports.”

American’s London Heathrow gateway cities in the U.S. will be: New York (JFK), Boston, Dallas/Fort Worth, Chicago, Miami, Los Angeles, and Raleigh/Durham.

In addition, while not directly related to the new “Open Skies” agreement, American will continue to serve London Stansted Airport from New York’s JFK Airport. American will add a second daily Stansted round trip beginning Aug. 1.
