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

Free wifi. Already pay a ridiculous fee for checking bags. With all those profits, snacks and entertainment should be better than 1990s

First class only upgrades seat width. The bottom cushion of the seat sloped forward so much that I was constantly sliding out of my seat. The meal was awful, granola and dried fruit? Seriously, for what I paid to upgrade? I can bring my own sawdust and rotten fruit for a whole lot less. Priority boarding is great except when you have a hundred economy passengers stranding in the aisle slamming you in the face with their enormous carry ons and smelly asses right under your nose. I want my money back for that leg of my trip. It wasn’t worth the money for such a minimal upgrade.

The crews on Alaska Airlines are really wonderful. They clearly know how to treat passengers with kindness and respect. During my trip, I discovered that my upgraded seat had been changed when reviewing my electronic boarding pass. When I questioned the change at the gate, the two staff members acknowledged that the change was odd, checked on their computer, and confirmed that I still had my upgraded seat (i.e., the electronic boarding pass was incorrect). I was impressed by how they seemed to be "in my corner" from the start, quickly investigated, and provided me with a paper boarding pass with the correct information "just in case." All that said, I was a bit disappointed that Alaska Airlines uses single-aisle jets with only four restrooms (3 at the back of the plane, one at the front (ostensibly reserved for crew and first class travelers). I would understand for short flights, but for a 6-hour flight from Seattle to Honolulu...really? I will stick with Hawaiian Airlines from now on.

Barbara at JFK terminal for Alaska was very helpful in retrieving our boarding passes for our connecting and quite pleasant!! Thanks

It was okay. Gate crew could be better organized. Wheelchair service for my mother was late as we deplaned. Flight crew was alright. I’ve seen better and worse.

Great! Wish we had more Alaska flight options in MSP

I was happy with my whole experience, and it was a smooth flight. Thank you

The people who worked for Alaska Airlines, both on the ground at O'Hare and during the flight, made it remarkable for me. Their customer service is incredible; they're kind of like the Nordstrom of the sky.

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.

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

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!

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

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.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

The entertainment wasn’t playing in the app or online.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

I missed this flight due to delays on my previous flight.

This flight was awful all around. Delays on the tarmac at PHL before takeoff and at the tarmac in Chicago caused me to miss my final connection. This was completely avoidable, in my opinion.

The A321(?) model of the flight for 5+hrs has no seat back screens. Getting the american airlines wifi experience to watch movies on your own devices is not the same.

For the money that I paid it was a good deal. I sat in the back of the plane and didn't pick a seat and my wife I sat together. Mission accomplished.

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.

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

Despite a bumpy flight the pilot was great. The rest of the crew on the other hand couldn’t care less if a passenger would colapse and die. Horrible service, robot like, lifeless…

No service due to turbulence. No entertainment on this type of aircraft. But nice old comfortable seats.
