Everything was great. Due to an accident on the Glen Hwy attendants could not make it to the airport. A delay while new crew was located

My experience with Alaska Airlines was great! Crew are always friendly and attentive. Alaska Airlines goes out of their way to make guest feel appreciated.

Completely full flight. Boarding was smooth, but people didn’t listen about use of overhead bins which is typical. We pre-purchased a snack which was tasty. Drinks were good and plentiful. Flight left late because previous flight was delayed.

Ok, but nothing special. Long flight with no blanket/pillow set.

The tray wasn’t cleaned, it had crumbs from the last flight Other than that it was very comfortable by

Kayak wouldn’t refund me for a flight I was trying to cancel through Kayak. Alaska airlines said I had to cancel through Kayak. I called the customer service line and they couldn’t refund the flight that I booked through Kayak either. You stole my money. You will be hearing from my lawyer.

Service was great! 👍 Seats were small and absolutely not enough leg and feet room!!!

Flight was delayed several times then eventually cancelled which caused issues with our hotel, car rental and tickets to planned event. We also spent unplanned expense with Lyft to and from the airport which was frustrating. Customer care was not present during whole time at the airport.

We received a check-in reminder the day before the flight, and it listed the flight at a later time. Correct flight number, same seats, etc. for 3 hours later. I called the airline to confirm and they had no record of the email. The info was wrong, and we would have missed our flight if we'd assumed it was correct. I want to know where/how we received this incorrect info.

My experience would’ve been great because we were on a new plane, but they said as we boarded that the plane would be too new to have WiFi, which to me is unreasonable - newer planes should def have WiFi! It was a 5 hour flight from Anchorage to San Fran and because there was no WiFi, I had to take an unexpected half day off work, which was super annoying because I had a lot to do and we only found out a few minutes before takeoff.

With a 24 hour delay, the Flight stared off rough. They had a nationwide IT Outage but communications to Passengers was very bad. Ground Staff and Ticket Agents were extremely rude and unhelpful. Perhaps they should take ground training from DL or Qatar. The food was horrible. Seafood was mixed with Bacon. Those two don’t have any space for Jewish or Muslim Faith Customers. The Airline needs new management.

Great. Clean. Seats comfortable. Food was free. Had new release movies.

The airplane I love and I love I came back safe thank you American airlines

Although there were two delays, they were communicated clearly and the boarding process was expedited. The crew was pleasant and efficient.

The flight I booked was conveniently timed, had one brief stop and was going to be quick. The flight I ended up getting was delayed, took longer, had a far longer layover and arrived hours later than planned. Thanks for nothing.

I take this flight about 6-8 times per year. It is convenient and saves an hour or two by skipping PDX, SEA, PHX, or ORD (but it takes longer to get bags to the carousel than Alaska Airlines). I wish the food service were better (but they might cut back on it because it is a red-eye). The WifI seems to go down about an hour out of Anchorage, and then comes back about an hour later...so be warned if this is an issue for you.

Flight was good. However, they had everyone board the plane then made us sit there on the tarmac for an hour plus due to maintenance issues. Besides that flight attendant and pilot were amazing.

Check in agent was helpful and nice. Flight was OK. Our flight in Chicago was delayed 8 hours without an explination. This was our journey home. After a horrible flight experience on on the way to our vacation where our plane was diverted for an emergency medical issue, was grounded for hours, we missed our connecting flight by 25 minutes, and it took a day yo get re-booked, this was yet another bad experience that American seemed unwilling to help out with, much less compensate us for the

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

Entertainment was very plentiful, staff were courteous. Seating was HORRIBLE. That is the most cramped I’ve ever been on any flight …Jet Blue and Spirit included. Very uncomfortable for a six hour trip.
