Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

You sent me an email saying boarding was at 9:29 and AA sent one that was 8:29 on Sunday morning. I had to call AA to get that it was indeed 8:29.

The airport crew and on board experience was fine. The problem with Alaska air is that there is zero customer service over the phone when you’re trying to buy your ticket or change anything.

The front desk attendant was rude to everyone in an absolutely careless way.

The boarding process could be clearer, there's never a call for group f

We left late; had to land in Minneapolis unscheduled to refuel and then landed in interior instead of lax at 2am......

good, no complaints but nothing to rave about. It was fine

I paid $168 each for myself and my daughter for an upgrade and we didn’t get any of the things mentioned by you/ site that comes with an upgrade. It was all just the same. One snack and one beverage. Nothing else. I don’t understand what the upgrade was.

Every thing is on time, boarding, landing nice and smooth. But No tv? No food for 6 hours flight?

I don’t think Alaska coordinates with Kayak. I did not get a “check-in” email inviting me to check in 24 hours in advance. Had to wait 20+ minutes to get a wheel chair.
