From today all Delta Air Lines flights from London will operate from Heathrow Terminal 3.
In total, Delta operates 11 daily flights non-stop to eight US cities from Heathrow.
These include departures to New York-JFK, Atlanta, Detroit, Minneapolis, Boston, Salt Lake City, Philadelphia and Seattle.
Delta joins its partner Virgin Atlantic at Terminal 3.
With all trans-Atlantic flights now under one roof, the move makes travelling on Delta and Virgin Atlantic even easier.
