British Airways has resumed almost all long-haul flights from Heathrow today, except six flights to the US.
Around 70% of its short-haul flights from Heathrow are due to run as normal, subject to potential delays.
At Gatwick, all long-haul and short-haul flights are back in operation, except for nine domestic flights.
BA Connect flights from Gatwick are running as normal.
A spokesman for the airline confirmed that over 400 flights had been cancelled yesterday – 364 in and out of Heathrow and 40 in and out of Gatwick.
“Our advice to passengers is to have a look on ba.com or cal the freephone number 0800 727 800 and check your individual flight details. We are still offering the option to re-book or get a refund,” he said.
He said it was too early to assess the financial impact of the disruption.
