I assure you AK Air is effected. We had 6 guests from 5 states try to leave Anchorage yesterday. 5 are stranded, all over the country after multiple delays and cancelations all night. My 86 year old MIL is back here sleeping after we dropped her at the airport at 10 PM for her midnight direct flight to ORD. She boarded at 12:00 sat on the runway for 2 hours and then the flight was delayed every hour all night and finally canceled at 6 AM and rebooked for SUNDAY. And, not direct but stopping in Juneau and Seattle.
I was able to use the AK AIr chat and get her changed to a flight Sunday with just one stop in Juneau.
Our guests had flights for Friday early and no one is looking at being home at least until Sunday night.
