Dozens of UK flights were cancelled on Monday as airlines continue to struggle with staff shortages.
British Airways axed at least 64 domestic or European flights to or from Heathrow - including a flight from the west London airport to Manchester. Other affected UK routes included Aberdeen, Edinburgh and Newcastle.
Among the international routes affected were services to and from Berlin, Dublin, Geneva, Paris and Stockholm. British Airways said passengers were given advanced warning of the cancellations. The airline decided last month it would reduce its schedule until the end of May to limit the need to cancel flights at short notice due to staff shortages.
