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.

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.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

The most cramped seating I’ve ever experienced, (including budget airlines) with no food available for purchase on a nearly 6 hour flight.

Flight was canceled do to mechanical failure I lost my connection flight at to pay $2500.00 more to get 4 more tickets to fly to Ketchikan Alaska This was the worst experience I had flying. I thinks kayak should pay for my new ticket from Seattle to Ketchikan That may bring less pain from my trip Thanks Ilir

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

AA1537 the AC was not working properly. It was very hot and uncomfortable.

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.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

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.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Did not realize seats did not recline. Best to travel in an exit row... No question

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9 hours of delay!! Was not able to check my luggage that I paid for!!!
