A number of British Airways flights have been switched at Heathrow following the closure of Terminal 1.
Services to Bilbao, Hanover, Luxembourg, Lyon and Marseille have moved to Heathrow Terminal 3.
Flights to Amman, Baku, Beirut and Cairo have moved to Terminal 5.
However, a number of long-haul flights are moving from the dedicated BA Terminal 5 in the autumn.
Departures to Accra, Cape Town, Denver, Las Vegas, Miami, Nairobi, Phoenix and Vancouver will shift to Terminal 3 from October 14.
Heathrow’s future plans include extending Terminal 2 to take over the space occupied by Terminal 1.
Airport chief executive, John Holland Kaye, said: “The closure of Terminal 1 marks another important milestone in the transformation of Heathrow.
“Terminal 1 has served Britain well for nearly 50 years, but will soon make way for the expansion of Terminal 2, giving Britain a world class airport that we can all be proud of.”
