It’s a good choice. Seattle airport is huge and confusing if you are changing planes. Have plenty of time to switch.

Very friendly staff, very responsive to complaints about the cabin temperature. 😁

...just O.K., I paid to upgrade our seating but seemed the same old cramped seat to me! What a rip off. Movie choices were minimal, lots of stuff not worth watching!!!

I was assigned a seat other than what I chose when I booked the flight. I chose a seat somewhat behind first class so that I could get off in a timely manner to ensure a wheelchair. Instead, I was assigned the handicap seat in the back row near the gross bathroom. I noticed when I got to the airport my boarding pass did not have my seat on it. However, when I spoke to the woman at the gate about getting a wheelchair for the onboarding process, I then saw a seat number on my boarding pass. I think she gave me a seat that I didn’t choose when I booked the flight. Now I wonder if I paid more money than what the back seat was worth??

The crew was pleasant! Our flight was delayed, and the pilot explained why. That was nice!

Flight was smooth and pilot was communicative with updates throughout the flight. Attendants were friendly.

I was traveling while very tired. The crew was very patient with me and I appreciated their kindness in addressing my needs. Having recently suffered a death in the family, I wasn’t prepared for the rigors of the day. They took good care of me and I was thankful for that. As for the rest of the flight that day, Alaska Airlines once again delivered a quality service. Every company has standards, and it is good to see the difference in quality of service when those standards are enforced! Keep up the great work!

I didn't use the entertainment options. Otherwise it was a good flight.

Flights were on time and everything went well thank you

The seats were comfortable, the overhead bins were ample, the staff was helpful, attentive, and friendly. I enjoyed free texting. However, I much prefer Southwest no reserved seats (take any unoccupied seat) and their policy of two checked bags free, and ability to freely change flights. The Alaska airplane was nicer and newer than the Southwest one. Overall, my Alaska Airlines flying experience was a very positive one.

The flight was delayed and I missed my connecting flight to LHR.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

Screen didn’t play movies, do I was pretty boated the entire flight.

It was very cold because the air conditioner was on high power, and my son got sick.

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

They did a fine job. Can't wait to use Delta in the future.

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

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

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

Overall fine but both ways for this trip was delayed.

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

See my previous comments. I was probably booked in business but was moved to economy

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

No water on the toilets, dirty sits. 4 hours delayed departure.

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

My flight was delayed for a whole day, so I lost a day of my vacation.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

The American flight was a connecting flight to an international flight. The international flight has a 2 check bag rule. Despite being informed of this, American would only check 1 bag and wanted 100 to check the second (basically a 3rd carry-on) to NYC. Subsequently tsa took a sealed container of maple syrup and a few other things that couldn't be in carry-on plus I had to lug around 3 pieces of luggage for the entire trip. The American reservation was made with the international and American actually checked the one piece the entire way to China. This is one of the reasons that I will avoid American airlines if possible in the future.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

It was freezing in there. When I asked about it, the response is “we would have to tell them” and then she just walked away and continued to serve beverages. Everyone was cold and they didn’t care at all.

I like the speed of boarding and deplaning and the fact that everything was on time. The crew (attendants) were probably quite new and did not begin the in cabin service until 30 min before landing even though there was little to no air turbulence for the last 1.5 hours of the flight. It made for a mad scramble at the end to get trash collected and carts stowed before touch down.

Everything went on schedule so I have not much to say. I was a bit disappoint with the breakfast choice - I did not have a choice as there was only one option left by the time the trolly came to my end and I could not enjoy it.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

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.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.
