Travelers flying with Alaska Airlines and its regional partner Horizon Air experienced significant disruptions after a technological failure grounded flights across the country. KIRO 7 reported that the issue, which began around 8 p.m. Pacific Time, prompted the airline to call for a ground stop. This measure lasted close to three hours before being lifted late Sunday night.

Despite the resolution of the IT outage, Yesterday morning's operations still suffered from the ripple effects, with passengers dealing with cancellations and delays. Alaska Airlines acknowledged the disruption and apologized to passengers, noting that the incident is expected to cause continued impacts to operations throughout the evening, as noted by KOMO News.

In addition to the inconvenience caused by grounded flights, some passengers were left waiting on the tarmac for extended periods, as illustrated by a video from an affected individual at Seattle-Tacoma International Airport (SEA). The situation slowly improved when, shortly after 11 p.m., Alaska Airlines declared the ground stop had been lifted and flights were to resume as normal. Yet, the experience was far from normal for countless customers scrambling to adjust their disrupted travel plans.

For those stranded or delayed, The Seattle Times relayed advice on how to navigate the situation. "Get in line to speak to a customer service representative if you’re at the airport, and call or go online to connect with Alaska’s reservations staff," advised The Associated Press. The article pointed out that travelers entitled to a refund should persist in contacting the airline, which must comply, even with nonrefundable tickets. And in times of high call volumes, reaching out to the international help number or leveraging the status of the highest-tier frequent-flyer in a group could prove advantageous. They urged civility toward the overburdened agents, who were working hard under pressure to assist. "And be nice: The agent on the other line is dealing with other frustrated customers and is trying to help you," the advice went.
