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.

The flight crew was very professional and pleasant. Our flight was delayed 3 hours, but Kayak informed me in advance

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!

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.

One hour waiting time after boarding, but arrived in time. I am satisfied

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

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.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

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.

Terrible, if possible won't be flying again anytime soon!

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

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

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.

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.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

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.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!
