Crew was great. Helpful, friendly, sense of humor. 👍🏽 Seat was really uncomfortable -- too concave ( why make them like that???) but worst, This is the first flight I've ever been on in my life where the seat did not have the option to recline!!! Whaaaat??? I was so sleepy but never was able to get comfortable enough to actually sleep. I forget which model of a plane it was exactly, but it was a 737 of some type.

You need another option on certain questions - ones that not applicable.

We had tried to change our seats in the app multiple times before check-in but the flight was seemingly full. When we boarded, there were several empty seats available that my husband and I were offered to take by one crew member only to be told by two others that those rows were reserved for the crew members’ bags.

One of the flight attendant was very rude and not helpful. The others were good. Also seats were dirty with food bags left on the seats. Looks like the plane wasn’t clean before we boarded.

Couldn’t plug in the computer to the electrical plug underneath the seat. Should accommodate a computer power line.

I don't know what it is. But it seems that flights from Ontario to Seattle are always delayed. This one was delayed 3 hours. I guess I should just expect it from now on.

Excellent, as always. Just a bit of comparison from the same routes. United has free blankets. Horrible terminal. EWR JetBlue. Updated terminal. EWR. Screens for each seat. Self service pantry and a lavatory in the middle of the plane. Alaska. Always has new planes neon lighting. Mood music for boarding and deplaning. No screens. Outlets yes. Offers water latter part of the flight. Which is nice. Excellent flight attendants. Customer service on phone or gates are always extra polite and friendly.

You sold me a $230 seat upgrade. But it was exactly the same seat as the $89 upgrade. The bait and switch seems to have become common practice.

It was Okay. I do appreciate the flight being on time and the happy crew.

We purchased tickets and were last to board while standby passengers were boarding before us. The WiFi wasn't working and the same thing happened on our last Alaska flight. The snack provided was vegan I wasn't going to chance eating that on a 6 hour flight incase it didn't agree with me.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

There was a loud squeaky sound the whole time we were flying.

We are a family of three, bought two economic tickets for me and my teenager daughter, a business ticket for my elderly mum who doesn’t speak much ENGLISH. During the flight my teenager walked up the plane wanting to chat with her grandma, stayed a bit and my mum consequently wanted to exercise so she walked down to our cabin too. My mum sat with me and chatted for about fifteen minutes then i went to business to check on my daughter only to find out she was not there. I was met with this extremely rude Hawaii Air flight attendant, after i told her my daughter is missing she couldn’t care less, she told me we can’t swap seats and insisted that i immediately return to the economy cabin. But then my daughter was still no where to be found! i explained and hoped that they could at least suggest some way to find her such as announcement or something, but the following words came out of her filthy mouth: “ Go back to your seat immediately! this is the last warning!” WTF?! i can’t believe this is the way Hawaii airline is treating their passengers and we paid business class fees! Very insufficient and incapable flight services as well by the whole crew. Overall extremely unpleasant flight experience! i will definitely spread words about this to ALL my family and friends and colleagues you name it. Never fly Hawaii Air ever again! Never!

Allowing passengers to move to empty seats if flight isn't full.

Enjoyed every stage of travel and really loved the free WiFi on the international flight. I would only make one recommendation. There was a lot of young children under 2 on the flight. Loud crying screaming and just playing. Constant poopie diapers. These families were spread through out the plane. Some of the passengers with no patience actually yelled at these parents unfortunately. I would recommend keeping all the families with young children in the same part of the plane if possible that way the passengers that complain can be relocated. In this situation there was no part of the plane that didn't have a noisy child. Any ways I will be flying Hawaiian airlines again because the service was just that good!

It was a 48 min flt......so no real comments can. E made

Friendly crew, flight left on time and arrived early. Had problems with using in flight entertainment on my iPhone, could not get it to work, with WiFi available. Liked being able to charge my phone. Overall a good experience!

The plane was nearly empty. My wife and I were seated behind a family with 3 sreaming kids. The parents refused to control their kids. When we tried to move to a quieter section of the near-empty plane, the flight attendant said please return to your seat. When we tried to explain, he stared at us coldly and simply repeated please return to your seat. When I asked if we could move after take-off he simply start and repeated please return to your seats. About as far from friendly and helpful as you can imagine.

It was a bit cold. The worst thing was the insecticide spraying which we were not notified about before the flight. There was no choice of complimentary food. I'm a vegetarian, and the food had meat. The seats were comfortable. The movie selection was nice. I'm glad I brought a headset, as none was offered. The flight times were very good.

Nice people, easy boarding, comfortable seats. But didn’t like being stuck in a seat that I paid for only to hear an ad read by flight attendant for the Hawaiian Airlines credit card. TWO different times. No desire to hear all that. Wish there had been a mute button. And flight attendant handing out applications at the exit was way too much, Otherwise all good!!!

The crews were very friendly and provided excellent service. They offered a breakfast sandwich on our early flight which was a welcome option.

The seating was very cramped. The selection of movies was poor.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Seats are outdated. Entertainment relies on personal device. Boarding was delayed due to inaccurate passenger tracking, resulted in late arrival at Reno.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

The crew and flight was amazing. I haven't flown United in years but plan to switch to you being my main airline

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

I am not an electronic savy. I don't know how to maneuver the APPS for services. Why can't I just buy food without the apps.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

Flights were on time. That's the main consideration since I had to change planes. The entertainment was whatever you bring with you and the food (in Economy) is non-existant. Neither of those was a surprise.

Mobility assistance at DFW is A JOKE!!! Totally disorganized, ineffective and annoying. Ended up having to walk and find our own way for a good part of the very, very long walk between gates. Worst assistance I have ever experienced.

This is a new route from Philadelphia to Naples. It was sold out. The team on board was excellent. I’ve flown this route twice this year and the flight has been excellent. I hope American keeps the route.

I did not enjoy continuously being lied to about the amount of time we would circle Chicago before deciding to redirect to Milwaukee. Then the amount of time we would sit on the ground in Milwaukee waiting for gas, or to take off again. Or the amount of time it would then take to get to Chicago again, or sit on the runway waiting for a gate. The whole time continuously hopefully we would make our connecting flight that kept getting delayed as well. Only to scramble and miss it. Enough with the BS. Tell me the truth. "Sorry, things are backed up and your probably not going to make your flight. You should rebook on the next flight now rather than wait." You'll never hear those words from an airline. Speaking of which. If the flight has been redirected and/or is seriously delayed, how about making the WiFi free for everyone so they get to rebooking and reserving hotel rooms while still in the air. You've inconvenienced me already and now you want me to pay $20 for Internet so I can try to make other plans. Absolutely disgusting!

Excellent. Attendants served preflight drinks and were courteous and nice.
