I was on AS 290 from EWR to PDX on 2/22. We diverted to Spokane around 8:30 PM. AS customer service was on top of emailing out hotel and food vouchers (though when I checked in to my hotel, the agent told me he'd just received six additional reservations from AS/ Expedia, and was giving me his last available room.) I called customer service and was told there were no flights available on 2/23, but that the situation with PDX was fluid, so I should check back in the morning.
I assumed I'd be rebooked, but didn't get any notifications overnight. In the morning, the elite line and the callback feature weren't working and I waited on hold for two hours before heading back to the airport. The agents there couldn't help, but they did tell me that our aircraft from the night before had already been ferried back to PDX or SEA empty, so that ended my hopes of getting a flight back. Ended up renting one of the last available cars in the city and driving to PDX.
The elite line started working again while I was driving (<1 minute wait), but the CS agents couldn't find any flights out of Spokane. Really unimpressed with Alaska on this for one of the first times ever. Both the lack of proactive rebooking, and the shrug when it came to explaining how I was supposed to get home. I understand weather happens, but there were 150+ people on my flight who are presumably trying to get to PDX and there just isn't much capacity out of Spokane to accommodate that.
