LONDON, May 28 (Reuters) - London's Heathrow Airport said it expected further delays and cancellations of British Airways flights on Sunday and told passengers not to travel to the airport unless they were rebooked on other flights.
BA resumed some flights from Britain's two biggest airports on Sunday after a global computer system failure sowed chaos, grounding planes and leaving thousands of passengers queuing for hours.
"Following a worldwide British Airways' IT system issue yesterday, delays and cancellations of British Airways flights are expected today," Heathrow said in a statement on Sunday.
"All passengers whose flights were cancelled yesterday should not travel to the airport today unless they have already rebooked onto another flight," the airport said. (Reporting by Guy Faulconbridge, Editing by Kylie MacLellan)
