From my interactions with the Oakland airport staff through TSA through the gate agents to the flight crew on Hawaiian they were just so kind professional and helpful.. the only thing I would add would be the they need more help and TSA and on the Hawaiian airlines flight it would be so much nicer for them to play beautiful Hawaiian music on the way over there.. they didn't start playing it until right before we landed..

From my interactions with the Oakland airport staff through TSA through the gate agents to the flight crew on Hawaiian they were just so kind professional and helpful.. the only thing I would add would be the they need more help and TSA and on the Hawaiian airlines flight it would be so much nicer for them to play beautiful Hawaiian music on the way over there.. they didn't start playing it until right before we landed..

The app is very bugy, did not work well. Other than that it was ok.

The flight was delayed an hour and it was not disclosed to the passengers until it was time to board. There was no in-flight WiFI available and such poor communication overall. Unfortunate that I was going to miss my connecting flight with poor communication on alternatives.

Broke the wheels of my luggage. Should be more gentle with other peoples belongings. Very upset about needing a new suitcase before Christmas.

orgiginal scheduled flight ( 2.5 hours connection) was cancelled, was given option to rebook between a 1-hour connection or a next day flight. Missed connection flight, and decided to book last minute with an other airline.

Short flight. Delayed because of ??. Had a water served . Staff was nice.

Crew members were helpful and responsive. However, the toilet in the only main cabin bathroom didn’t work properly.

Upgrading my seat online was a breeze, boarding was easy, and we had such great tail winds that we ended up getting in 20 minutes earlier than planned.

Flight was delayed because overhead bin didn’t close. The most insanely stupid thing I’ve ever heard.

Interline connection was terrible. Boarding pass from American didn’t work even though it was valid. Gate agent not present to straighten out the mess until the next to the last boarding group was called.

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

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

I love that every seat has a USB charger. The seats were comfortable and everyone was friendly! I can't think of anything I would improve.

Going to Kahalui was wonderful. Attendants were awesome. Coming home, I was bumped from the seat I originally booked. Imagine my embarrassment as I stood there knowing I booked my flight a month earlier. All in all, I didn’t allow that spoil a wonderful weekend in Maui with family.

Wonderful flight. Food and drink were given as well as wifi. Amazing luxury!

2nd flight of the day, delayed from the 1st flight being inoperable, and then this one was delayed 45 mins too.

The flight from LAX had broken AC; they deplaned and sent everyone to a gate with no agents, so I called HA to try and get rebooked. Customer service was great; I at least was not being put up in a hotel for a night this time. If I hadn’t called, well, that original flight I was on got cancelled before I landed in HON. The result was arriving over 7 hours late and missing a half day of an appointment I should have easily made even with a small delay.

A great experience with no problems! Hawaiian Airlines is amazing!!

Boarding was efficient and everyone helped with putting luggage in the over head compartments. The crew distributed food and drinks well.

great experience, excelent aircraft, crew, services onboard a dream come true

The check in women was very nasty attitude to the passengers from Lihue airport flight 68

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!

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Had a hard time finding my assigned seat. No attendants to assist.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

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

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

It was as expected for such a short flight. No complaints

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

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.
