On this flight there wer only 25 people on board. So no one in 5 rows ahead of me and noone in 7 rows behind me. So very chill.

Generally Good. Outbound flight was marred by a continuously s creaming baby. Fortunately the flight was only 90 mins long it would be nice if people traveling with small childres could be centered in one part of the plane. Also, you need to adapt your servey to include a "not applicable " option for things like food and entertainment, which are not offered on shorter flights. I fily Alaska by choice as given all the cirumstances, I fel\el you do a good job.

Fine for a short flight. All went well. Snacks are lacking and I couldn’t hook up to wifi through the app, but it was fine.

Aircraft was freezing, cold air blowing on me the entire time and the individual fans were turned off.

Alaska used to be a top notch airline. With it's growth it is now in line with the big airlines. Not bad, not great.

Great. I did have a little issue getting into the Lounge, which is likely more an American Airlines issue. I did not carry my physical AAdvantage Executive credit card with me on this trip, which Admirals Club membership is a part of the benefits of having this card. The instructions on the AA website and the Citi cards website make it seem like you don't need the physical card, as both sites state you can enter with your boarding pass and driver's license. But both lounges said you were required to present the physical card (and not the digital version, via Apple Pay), as only the physical card says "Admirals Club" on the back.I also do not have a physical Admirals Club membership card, so while both lounges eventually let me in, both denied me entrance initially for this reason.

Everything from the time I booked my flight through to the end when I got home was smooth and wonderful. Service was great, the flight attendants were attentive and there were no outstanding delays.

Delayed and no entertainment? I also forgot my headphones and immediately reported it and have not heard back yet.

The crew was very friendly. Boarding was quick and efficient.

we waited for 50 minutes to check a bag and missed a flight. do better.

Flight delayed two hours , missed connection flight then connection cancelled- horrible experience with hotel

The checking was disaster, the crew wasn't behave well. It took us two hours to check in, after that thr line at the TSA was long, we barely make the flight. Bad airline

I like that if they asked you to checked in a bag at the gate they give you priority to board

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

I like Hawaiian, it was great that they had good internet connection across the Pacific Ocean, thanks to Star Link satellites. The seating was comfortable, ( I was in economy ). Maybe I missed it, but I only got offered a beverage once. It was a nonstop flight KOA to SMF. I would take it again next time I go that way.

Previously flown Hawaiian Airlines on similar routes, I found Alaska Airlines to be noticeably more comfortable. The seats on Alaska Airlines provided better support and cushioning, which made a significant difference on the long flight to the islands. When you’re spending 5-6 hours in the air, seat comfort really matters, and Alaska Airlines delivered where it counts. After comparing both carriers, I’ve decided to book with Alaska Airlines for all my future Hawaii trips. The superior seat comfort alone makes it worth choosing Alaska over Hawaiian Airlines. If you’re planning a trip to Hawaii and prioritizing comfort, I’d recommend giving Alaska Airlines a try. You won’t be disappointed. Highly recommended for Hawaii travel!

I received several emails about my 3:10 flight. When I showed up to the airport at 12:30 to check my bags I was told the flight was actually at 1 pm. They grudgingly rebooked me for a flight at 5:22 to Vegas to get a connecting to LAX. I did find the gate for my original 3:10 flight but they were booked. I proceeded to receive status updates and gate change information for the 3:10 flight, even though I was apparently never supposed to be on that flight

The crew was EXTREMELY helpful And sweet and the flight was smooth!

I wasn’t able to check in early and I wasn’t able to get an aisle seat without paying $120.

The Kayak confirmation number did not work for checking in the day before. I checked in at 8.30 using my ticket number. When I arrived at the airport, I was informed that the flight was overbooked, and since I had checked in late, I did not have a seat. The Next flight was not until ten PM. I called my wife, who had been taking care of our kids all weekend, and she was upset, calling me a liar and telling me to stay in SD. It turned my weekend getaway into a nightmare! I blame the Kayak website and will not book flights using your app in the future.

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

Wifi was spotty. Tray table was very dirty when I sat down.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Buying ticket from kayak instant booking was a huge mistake, never to be repeated again! The Kayak didn’t book the tickets directly, it handed it off to a third party Underpricer, that booked a code shared American Airlines flight operated by Cathay Pacific!! When managing the booking American Airlines would recognize the itinerary but wouldn’t let me do anything stating, the flight is operated by Cathay Pacific so go to their website. Cathay Pacific would recognize the itinerary, neither by reservation ID or ticket number…asking to reach out to the third party Underpricer….calling Underpricer resulted in no help like seat requests, mileage number or upgrade request, 15hr layover accommodation voucher guidance…so net in net avoid booking through three layers of intermediaries

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Delayed for mechanical and no updates on what was happening and how long the delay might be.

There weren't enough employees at check in took awhile to get bags checked. There wasn't a wheel chair for me, I was sent to someone who turns out to work for a different airline, if My flight hadn't been delayed I probably would have missed my flight as it was, by the time I arrived at my gate, they started boarding in about 15 minutes. I don't know who took me to my gate, definitely was not the normal people who take passengers to the gate. I'm guessing she may have been in a management position. I wish I knew her name, she went beyond to help me. With that said everyone was kind, and were doing the best they could. So, I choose to say it was an Adventure, stressful start, but good. In the end went well. The situation was not only difficult for passengers but the employee's.

The staff at the check in counter was so rude. Made you feel Incompetent

Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.
