Delta Air Lines said it was not expecting flight cancellations as a result of a technical glitch that had affected booking, check-in and boarding services.

"While we expect flight delays to extend into the evening at some of our busiest domestic hubs due to this issue and weather, we do not expect any technology-related cancellations," the U.S. airline said in a statement.
