PORTLAND, Ore. —Computer problems that delayed about 30 Alaska Airlines flights were resolved by Thursday morning, the airline said.
"Everything is all back up and operating normally this morning," airline spokesman Cole Cosgrove said around 6:15 a.m. Alaska time Thursday.
A brief airline blog post at 5:30 a.m. also reported that all computer problems, which started the night before, had been fixed.
Late Wednesday night several computer systems ran into technical problems, including programs for passenger check-in and for pre-flight departure paperwork, Cosgrove said.
As a result, about 30 flights were delayed across the Alaska Airlines system, he said. As of 6 a.m. Alaska time, all delayed flights had taken off, he said.
The company advised passengers to check the status of their flight before leaving for airports.
Alaska Airlines travelers at the Portland, Oregon, airport late Wednesday said they were told their flights were delayed as a result of a system-wide technical glitch.
Computers were not working at the check-in gate, forcing employed to hand-check every passenger against the manifest and physically check off their names as they presented their boarding passes.
Flight 143 from Portland to Anchorage was delayed by at least two hours.
That affected Kevin Rentz of Pensacola, Florida, who was trying to reach his job in Alaska by noon Thursday.
He said one impact of the delay was that he would probably not be getting any sleep.
"I want to get some rest before I go to work," he explained in an interview at the airport.
The extra wait prompted other travelers in Portland to find places to stretch out and doze off.
Cosgrove said the airline's IT employees fixed the computer problems overnight and, as of Thursday morning, the problems had not resulted in any flight cancellations.
