British Airways have extra staff on duty as it transfers some of its long-haul flights to Heathrow's Terminal 5 (T5), which opened amid chaos two months ago.
BA is hoping that the move will not be accompanied by the same shambolic scenes when operations began at the £4.3 billion T5 on March 27.
Almost everything that could go wrong did. Flights were cancelled, bags went astray, lifts did not work, staff struggled to get through security and huge queues built up.
BA had hoped to move almost its entire long-haul operation from Heathrow's Terminal 4 to T5 at the end of April.
But the disastrous T5 opening prompted BA chief executive Willie Walsh to postpone the long-haul move.
First, BA said the transfer would take place in June. But the airline then announced that some long-haul flights will move today, some on September 17 and the rest around the end of October.
Today, BA will move eight routes from Heathrow Terminal 4 to T5, including the lucrative eight-times-a-day service to JFK airport in New York.
A BA spokesman said: "We have more rostered staff on duty today and we will have extra staff on hand who have volunteered."
The other seven destinations transferring today are Abuja and Lagos in Nigeria, Bangalore, Beijing, Cairo, Cape Town and Phoenix in Arizona, USA.
