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.

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.

Full flight where I had another passenger sitting in middle seat who said that he had lost 250 lbs from 500. The stewardess on exiting the flight advise me that I was going to receive a refund. I thought she was talking about another passenger. The stewardess saw that to make him comfortable I had lifted the armrest and flew for 5 hours to Seattle from Reagan DCA with a portion of his body on my seat. I survived. I flight to remember!!!!

the flight was delayed almost 3 hours and not one time was we told that it was delayed or why. I had asked one of the crew members why it was delayed, 20 minutes after the flight was supposed to take off, and was told that they had no idea what was going on and that they had not been told anything. this is FRIGHTENING!!!! No excuse!!

Flights were on time. Check in was fine. Crew members were pleasant.

I would have liked it to have been easier to order food for the flight. My son was not happy with the snack pack I bought him and it was a very long flight for a little boy to go without food.

Ground staff at LAX was very helpful. The Alaska lounge food and service is better than most airport lounges. I think the Staff are well trained polite and actually seem happy to work there. Great service Thanks 🙏 Jjk

The flight was very very delayed and arrived much later than planned. There was no communication about why or when our arrival would be. I would expect better and open communication about the flight but there was none. Also just pretzels? How disappointing.

I got to my destination but no comforts no snacks nothing. Like herding cows!!

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Boarding - It is unclear where the line for the group are given the signs. A solution would be a diagonal arrow pointing to the lane in which the lane for boarding of a given zone should form. As it is now, you are guessing which side of the pole the "zone 3" sign is telling you to form the line. Inflight Entertainment - The Spanish subtitles function didn't work for movie watching (in fact, all subtitles didn't work), so was difficult to follow along and I watched the movie in silence without words.

An hour-long wait to check in, 90 minutes for luggage to come out, lost luggage, chaotic operations

Business class was economy with a table in the middle seat. That is worse than economy. No food and no entertainment. Very poor representation.

I like the plane , but i was 50 mts before my fly and they didn’t let me document my luggage, so they told my that I have to leave my luggage or buy an others tickets , because they didn’t want me to give me credit for the tickets I have so that is abuse from the company , and on the line it was 5 families with the same situation equal lime mine , I think they doing business with the tickets w people ,; Mexico has a bad working people, the rip money from turists, and is bad because give bad impression of the company that is aereomexico

No everybody brings the proper equipment to enjoy the plane entertainment. Then I was not able to enjoy it.

Pros: "I like the service ,the food in thos fliggt back. Excelent"
Cons: "Better rules for people who put the seat back while we eating ,some crewmembee could say something"
Pros: "Crew friendlynesd"
Cons: "Paying a little more attention to the seating. Not everyone was socially distanced. Seat rows were unequally distributed: some were all full others were too empty."
Pros: "Seat was okay, but I thought we weren't doing center seats because of Covid risk. That plane was packed tight."
Cons: "They made me store my bag, because I had a guitar which has always been allowed as a carry on. Its a fragile instrument, and has always been allowed as a carry on."
Pros: "Nothing"
Cons: "Everything, I will never going to use this software anymore."
Pros: "Flight was late, lost my conection and gave me a flight for next day"

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the price of premium class ticket paid, felt more like steerage.

I have to wait for plane in Denver for three hours. I don’t receive my luggage in Denver. I come back home without the luggage and I wait till next day to see my luggage again. Not really good experience with United airlines. I’m sorry to say that.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I had a great flight. Everything went smoothly and the flight arrived early.

Everything was great except for one thing. I was sitting in seat 1L with plenty of windows. Because we couldn’t sit next to each other, my husband was in 2L with only one window that he had to almost turnhis neck around to look out. Therefore, the window position with 1/2 of the “window” seats in business class is not optimal

Flight was late due to mechanical, had to spend night in hotel. Experience disembarking plane was poor, United did little for passengers except what they were required to do by law.

If the flight is delayed, get the delay timing right and don’t have people standing in line ready to board for almost 2 hours because you keep pushing it back. Also, don’t have your flight crew say they are sorry when they clearly don’t care, make no efforts to speed up anything and then turn around and are rude to customers when they don’t “move fast enough” to put up tray tables and seat backs.

I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.
