SkyWest Airlines says a disruption in its computer network kept its flights throughout the country from taking off for about two hours.

Spokeswoman Marissa Snow says the system went down about 5 a.m. Mountain time Sunday and was restored by about 7 a.m. She says that service from the airline's network provider was disrupted. That kept pilots from getting information about planes including fuel amounts, weight and balance.

Snow says ongoing delays of 90 minutes to two hours are expected on flights throughout the day.

SkyWest is a Utah-based carrier that services flights for United, Delta, US Airways, American Airlines and others. It was ranked 11th among major airlines in on-time arrivals in September.
