Monday morning, the airline released a statement apologizing for the delays and reads in part: “Today we are expecting the technical systems that power our Customer Service to perform normally. Teams worked throughout the night in advance of our first departures to ensure the smoothest operation of our originating and later flights.”

The airline said it was working “to get bags delivered and some delayed or displaced customers into open seats.”

Passengers are advised to arrive at least 2 hours early and to print out their boarding passes in advance.

So far, no word as to what caused the problem, but a spokesperson said it was not caused by hackers.
