by Thousands of passengers had travel plans into chaos after Alaska Airlines was forced to ground all planes after an IT failure.
The airline experienced a “failure that led to a temporary, system -wide soil stop for Alaska Airlines and Horizon Air flights” at 8 p.m. on Sunday (Monday, Monday in Great Britain).
Later it was said that the operations were resumed and the system had come out for about three hours.
But it says: “While we reposition our planes and crews, there will most likely be an impact on our flights. It will take some time for our overall operation to be normal again.”
“Please check the status of your flight before going to the airport,” he added.
Details about what the failure has not yet specified.
It remains unclear whether Alaska’s failure is related to Microsoft on Sunday that there are “active attacks” on its server software used by government agencies and companies.
Alaska Airlines has solved his former IT failure and resumed the company. We sincerely apologize for the inconvenience and encourage guests to check their flight status before we go to the airport.

Alaska did not immediately respond to an inquiry in which a comment was asked whether the failure is related to the Microsoft announcement.
The Federal Aviation Administration website confirmed a floor stop for all Mainline and Horizon aircraft from Alaska Airlines.
Horizon Air is the regional subsidiary, which runs Alaska Airlines flights.
According to its website, the Alaska Air Group maintains an operational fleet of 238 Boeing 737 aircraft and 87 Abraer 175 aircraft.
In June, Hawaiian Airlines said, also owned by the Alaska Air Group, and some of his IT systems were disturbed by a hack.
In September, Alaska Airlines announced that he briefly justified his flights in Seattle because of “considerable disturbances” by a non -specified technological problem that was solved within hours.
