Seats extremely uncomfortable, no entertainment, no snacks, and when boarding, half of the passengers needed to check in the carry on luggage without any explanation.

Seats extremely uncomfortable, no entertainment, no snacks, and when boarding, half of the passengers needed to check in the carry on luggage without any explanation.

The flight was jumping between being delayed and closer to schedule about 5 times. Alaska air website showed incorrect times while google had latest info. This panic was horrible to deal with.

I always heard this was a terrible airline but I was happy to experience otherwise. The seats were more comfortable than delta. They did board late and gate was a little chaotic, which is to be expected for a budget airline. I would definitely do it again for that price.

Very expensive for short flights. Can’t communicate with Alaska Air about passport issue at check-in. Also no replies to my text messages. Wanted to extend our vacation for two more days but this expensive flight ticket is called SAVER and I couldn’t make changes or cancel or get a credit even, so I paid another airline for the return trip. Extremely disappointed.

They canceled my flight then changed me $155 for the same flight the next day

Our flight time was drastically changed which caused us to lose a day of vacation

I like the new adjustable headrest. Unfortunately 2 crying children were in front of us. But it was the first time and not holding Alaska accountable for that. Alaska always seems to have everything in order professional but comfortable.

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors

The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

My husband upgraded our seats and I don't know if it was due to the type of planet was or if they didn't upgrade our seats. We were supposed to be in I believe comfort seats and they were just as tight as any other seat- no leg room and we are very tall people but at least it wasn't extremely cold. My husband did put in a complaint about our seating because he paid extra and if we would have known that the space and the tightness would have been the same, we just would have gotten the emergency row emergency row seats that we normally get. We love Delta but both our flights coming home we're not good. Oh I forgot to mention that on our flight to Hawaii our luggage wheels got broke and we had to purse new luggage on vacation then we never had this problem so we didn't know protocol and reported it after we got home only for them to tell is we only had 24hrs to report the damage. Not sure what was going on with Delta this vacation trip.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Delta flight was on time, seats were comfortable, and crew was nice.

The flight was great! The flight attendants were friendly and attentive. I would definitely fly Hawaiian Aurlines again!

You have to buy the ear buds and they only offers little cup of water twice.

Departure was two hours late! Better than four hours late on our first flight

Miserable. Birthday trip for daughter booked for Cabo. Her plane was canceled and the best they could do was get here to fly north to San Jose, CA, stay in a hotel, sit around half a day and finally fly to Cabo late the next day. 36 hours traveling and wasted time. Missed a night of a booked resort, missed here ATV excursion, etc. I know it's a "first world problem" but it still was incredibly inconvenient, and wasted a good deal of money. And almost all the "service" people, in person and on their support lines, were not helpful. They were as useless as an automated AI assistant.

The flight was supposed to leave at 7:30pm, but departed 10:50pm. They kept moving departure time out every half hour. It was a 45 minute flight from n Sunday night with great weather.

Flight got delayed and it was very inconvenient . Had to come with another carrier. Had to spend one more night in San Francisco.

Everything was good for the price I paid. Crew was very nice.

The worst flight experience I've ever had. Our flight was delayed 14 whole hours because the flight crew never showed up. We had to wait in a two hour line to get our new boarding passes, we were told we had no other option but to fly at 10pm (we didn't depart until 11:45pm). Everyone had to contact their hotels and car rental places, workplaces, etc. since we lost an entire day's worth of travel. The crew showed up at 10:15, which was past the time we were supposed to board. They were laughing and being completely smug when they boarded, and they took another hour to board us onto our flight. The flight crew never came to check in on us, we were quickly given one drink and sandwich and they turned off the lights and were negligent the rest of the trip. My mom asked three attendants for a seat belt extender, they never brought one. I was dehydrated and never received another drink. They were very rude and unfriendly, we had been up since 4am the morning of our flight and didn't land in our destination until 2am the next day (5am local time). This was unacceptable service and treatment, these flights are not cheap and we were inconvenienced out of an entire day of travel. This was 100% avoidable and was the fault of Hawaiian Airlines, and their crews inability to show up to work on time.

Loved the leg room, usb charging, outlet, food, staff. The seats were very uncomfortable for some reason and made my buttocks ache and would have liked to be seated together from the time of purchasing tickets without having to pay extra.

I was put in seat 6B with no warning. Had no seat in front of me just sticks out in the aisle so I had to hold what I could and put the rest in a bin way further down.

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The best airline I have ever travel , really good customer service, attention and service !!

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

Boarded plane and then delayed 1.5 hours while on the plane

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

They rescheduled me and I had no issues with the new flight

No paper towels in bathroom. Aisle seat difficult to get out of Other than those, excellent service

Both flights are delayed so I rate the whole experience as mediocre.

Bad experience boarding and flight got delayed didn’t make it to my next flight

The food on the trip Toronto to Athens could be better: the chicken didn’t taste good.

Before final boarding, my husband and I — both seniors — were told that we could not bring our carry-on bags with us due to being in Zone 6. The staff took our bags with little explanation, stating it was policy. While we understand boarding procedures may vary by zone, the way we were spoken to was unnecessarily rude and dismissive. We felt disrespected and singled out, and the interaction left us deeply uncomfortable. As seniors, we expect to be treated with courtesy and dignity, especially during travel when accommodations and communication matter most. We hope you will look into this matter and ensure better training for staff in handling such situations with more empathy and professionalism.

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers
