About a dozen flights on Alaska Airlines and Horizon Air were delayed Sunday due to crew scheduling problems, but airlines officials said they fixed the central computer system that forced the cancellation of some 150 flights Saturday.
Thirty of the affected flights left from Seattle-Tacoma International Airport.
“Everything was back to normal” early Sunday after technicians repaired a malfunctioning transformer that crashed a computer system, said airlines spokesman Paul McElroy.
Flight delays prompted by crew scheduling conflicts “were all over the place” and some delays were more than two hours, McElroy said.

The glitch occurred about 3 a.m. Saturday during the installation of a backup power system. While the system was operating on a portable generator, a transformer malfunctioned and crashed the entire system.
About 12,150 passengers were affected when flights were canceled Saturday.
