Thw crew was excellent but due to poor scheduling Alaska Airlines routed our flight to LAX then LAX to Seattle. This delayed our arrival at the airport by at least 5 hrs and really inconvenienced us in many ways...

We loved the extra legroom on the flight and the fact that we didn’t have any one beside us.Everything was a n time and satisfactory.

I booked flight for my son. He had an epilepsy episode while in line boarding the plane. No refund. WTF? Never again book with Kayak.

The queue before check-in was long and slow moving due to too few desks being open. THEN, WHEN WE FINALLY REACHED THE CHECK-IN DESK WE WERE CHARGED US$70 FOR 2 BAGS. What rubbed salt into the wound was the incredible number of large bags in people’s “carry on”.

I was unfortunately placed in the middle seat. Very, Very cramped.

Flight was on time, boarding was efficient, and crew was pleasant. It would have been a nice feature to have the seatback tvs as this was a cross country flight, but entertainment is not a requirement.

It was all good until they had a mishandling issue with a couple of our bags but overall it was fine and we got the bags eventually

The flight itself went well, except it left 1.5 hours late, and about 10 of us missed our Alaska Airlines connection by minutes; they wouldn't hold the plane, even though our arrival delay was caused by Alaska. No gluten-free options among the snacks; you had to order meals separately, but there was no consideration for food sensitivities. NO TELEVISION on a flight from Washington, DC to Seattle or from Seattle to Anchorage. I didn't know that ANY airlines offering cross-country flights didn't have screens for entertainment. This alone is a "never again" for me.

I have to eat gluten-free due to celiac disease, but so far no Alaska Air flight has offered a gluten-free option for the snack given out with free drinks. It seems like that wouldn't be too hard to do.

I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

Re-checking our bags, the workers were not able to help us with boarding passes for the flight, told us to wait, then ignored us while they helped many other passengers. Until I got rude, they would have left us standing there, and even then they were very curt and dismissive in telling us where to get boarding passes printed. We made it to the gate just as they were starting to board passengers. It was just rude customer service.

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Absolutely filthy flight and not equipped for a trans US
