May 29 (Reuters) - London's Heathrow Airport said early on Monday that there were still some disruptions to British Airways flights from the airport following a global computer system failure at the airline.
The airline resumed some flights from Britain's two biggest airports on Sunday, but hundreds of passengers were still waiting for hours at London Heathrow.
"We have mobilized additional Heathrow colleagues to assist passengers at the terminals and give out free water and snacks," Heathrow said in a statement on Twitter.
The airport said earlier that further delays and cancellations of BA flights were expected on Sunday and told passengers not to travel to the airport unless they were rebooked on other flights.
BA cancelled all its flights from Heathrow, Europe's busiest airport, and Gatwick on Saturday after a power supply problem disrupted its flight operations worldwide and also hit its call centres and website. (Reporting by Ismail Shakil in Bengaluru; Editing by Peter Cooney)
