MGN LONDON (AP) Travelers with airlines in the British Airways group faced a third day of delays and cancellations, mainly on short-haul routes and in smaller numbers than over the weekend, when the company suffered a colossal IT failure. BA chief executive Alex Cruz said late Sunday the airline was running a “near-full operation” at London’s Gatwick Airport and planned to operate all scheduled long-haul services from Heathrow. But he said there would still be delays, as well as some canceled short-haul flights. Data from flight tracker flightaware.com showed BA’s sister airlines in Spain, Iberia and Air Nostrum, cancelled over 300 flights on Monday, a bank holiday in the U.K. that sees a high level of air travel. BA itself canceled another 27 flights and had 56 more delayed.
