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.

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.

5 1/2 hour trip. Nice plane. easy boarding. Could have used a bit more beverage service but it was a red eye flight and they didn't want to wake everyone.

I was very pleased with this trip from Anchorage to Seattle and Seattle to Billings. Wheelchair assistance was rendered and gratefully accepted. Unlike my outbound flights to Seattle I did not have long, painful walks on a bad knee to get to airport gates. My thanks to the Alaska staff.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

To san Francisco it was ok. From sf to Manila it was horrible

You have got to come up with a better way of getting connecting flight people off the plane first. Flying doesn’t bring out the best in people but exiting off a plane rules needs to come from management, not from the expectation that passengers will be “kind” and let them off first. Perhaps exiting in zones? Like boarding? Zone 1 exits are connecting people. This frustration led to many people missing their flights or scrambling. We were delayed leaving the first leg which amplified this.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

The seat was not even cleaned. It has full of cookie crums probably from last flight's passenger. Its basic expectation that, seats are clean.

Crew was great! Food sub-bar, tepid & flavorless. No snack options on trans-atlantic flight. Premium Economy seats ok, leg rest wouldn’t stay in place.

The planes can use an actual cleaning. The armrest and seats do not appear to be cleaned on this one and most other planes.

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.

Pros: "This was the worst flying experience I have ever encountered."
Cons: "We sat on the tarmac 3 hours, then deplaned to a holding area for another hour and then were told the flight would be delayed until 1 pm the next day. I booked this flight in order to arrive home 7 hours earlier than originally planned on Alaska Air. I finally arrived 20 hours LATER THAN I WOULD HAVE ARRIVED!"
