All good. Great food and entertainment when there isn’t any on a one hour flight

Flight was delayed twice, I was forced to check my bag, and the only offered water or apple juice on the flight

Plane left an hour late due to flight staffing problems. Only a 45 min flight, but it took 3 hours as a result, which left a lot of people disgruntled. No excuses. No recompense.

Paid for first class, but the flight attendant for first class did the minimum required. She really ever came to pick up the trash, and never asked if we needed anything. Every person had to ring for the flight attendants if they wanted any extra drinks. When I went back to use the restroom, she was just sitting on her phone.

Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!

When we checked in our luggage, we had to use the tray, but include this tray is extra weight. I think you should not use the tray.

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..

Crews ADA compliance ecellent. Sensitive and kind observation involving several passengers on plane Plane clean and fresh includsing lavatories

I flew from San Francisco to Honolulu on Alaska Airlines codeshare with Hawaiian Airlines, with a Hawaiian Airlines plane and crew. The flight was well organized, including boarding and deboarding. The crew was professional. Unfortunately, the charging ports at my seat and the seat next to me were broken. The Hawaiian airline terminal was a pleasant surprise compared to the rest of Honolulu airport.

We were amazed by the amazing food, comfort and service received in our coach seats. Pleasantly surprised we received breakfast and great beverages for no charge. Bag check fee was on $35. The crew was so kind and helpful. Highly recommend!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

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!

Boarding was a nightmare. Almost everyone was on group 4 and there was no line people crowded the check in and made things more chaotic than they needed to be.

Hawaiian airlines canceled my flight the night before my a due to weather. This is fine, I know this happens. In the email alerting me to the cancellation they said they would reach out to reschedule. I got this email at dinner time the night before the trip. I didn’t hear back so I called and was on hold for hours, I tried their texting questions option and never heard back. I tried to chat with a representative online, the website says you can chat and have questions answered but there is no link to a chat option anywhere on the site. After hours trying to get someone to communicate with me about the details of the cancellation and my rescheduling options I have up, got the flight refunded and booked a much more expensive last minute flight. Nonexistent customer service, I’ll never fly Hawaiian again.

The flight crew made the trip pleasant considering they had to work in conditions similar to a sardine can.

Having enough fuel to get to our destination seems like it should be a given when you board a plane. Not in this case, delayed hours to refuel.

Friendly & on Time .Need to make sure the Hana Hou magazine is in front of each seat

The leg room, complementary WiFi and food and drinks. Friendly staff

Most of the crew was wonderful but I had one bad experience with a crew member. When realizing my seat did not have an outlet compatible with my phone charger that I would need for transportation upon landing I asked an older, blonde heavily madeup member (I am describing her as I did not get her name) if there were chargers elsewhere I could use she said no, that not even the flight attendants had access to any. This however being my second flight of the day with Hawaiian airlines on a similar plane knew that chargers were available in extra comfort seating. I asked another passenger if I could use their plug and they agreed. She twice berated me for this and when I asked her to please stop talking to me about it she yelled that she was writing me up and ran down the aisle and did not return. I found this behavior disturbing. The other passenger was not bothered and this didn’t appear to be a safety hazard to anyone but it seemed to enrage her that used a plug that was not next to me.

The food was good but for the landing we had to wait 30 mins for the other plane to depart to its destination

I would like diabetic options for food. Seating was a little tight. Everything else went smooth

Good service because of wheelchair. Tight seats. Some announcements were hard to hear or understand. No directions for working the seat video or meanings of the icons. Coming into the country and changing planes was terrible with long lines and few desks open at the end. I had to go through twice because they found my tiny knife with fingernail scissors and file, when they scanned my checked luggage, and in order to keep it. I had to go through that long line a second time. Going home the luggage was checked all the way through

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

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.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

Angela was the best fa ever. She made that 8 hour flight a breeze

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

After several delays and being rebooked onto a layer flight, I had to speak to three AA agents for baggage claim to get an attendant. All were in foul mode and reluctant to assist or offer any assistance.

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.
