It's no surprise that Alaska Airlines is having problems with flight cancellations and delays right now. (Though, I didn't know that when I booked the tickets.) However, the late notice for changes is infuriating. While I was riding into the airport, I got the notice that my flight was delayed by an hour. Half an hour after the delayed boarding was set to begin, we were told the plane would land in 7 minutes. The plane actually arrived about 30 minutes later. I don't get how you miss by that much, as 7 minutes out means the plane is already on final approach. We finally got on the plane, and were told there was a small maintenance issue being taken care of, and we'd be off in like 5 minutes. 15 minutes later, we were still sitting there with no updates. In the grand scheme of things, they got me home just a couple of hours late. The lack of communication just left a bad taste in my mouth.
