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!!!!

Easier to file a claim. My fiancé got the flu and we had to cancel. ive been given the run around filing a claim. Call me at 831.588.4346 with a live agent please

My seat was comfortable. There was no TV on the airplane.

Flight delay was inconvenient and exhausting getting in at 1 am. However the crew and lounge was very comfortable.

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!

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

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

Service was so slow. I didn't get enough food and drink.

WiFi was not working thus the entertainment system did not work! Over 5 hours with nothing.

The extra leg room seat I paid a premium for was not at all what I expected. Everytime the person in front of me reclined the seat my food fell off the tray. The person behind me kept putting her knee in my back.

I sat in 17G. I was not aware that I was behind a jump seat with no leg space or pocket to store stuff.

The plane was very old. No screens on the back of the seat and there was obvious wear and tear in both the bathroom and the seating areas.

Plane had screws missing from engine cowling. Retire that POS

Some staff were very nice. Others were whatever. Plane was 2 hours delayed. Food was absolutely horrible. Nobody likes a turkey croissant. Gross. Serve something healthy and Hawaiian. Free internet was awesome but we only got that because we were 2 hours delayed. That should be standard on all flights, free internet. Luckily we made our connection but the plane on the connecting flight was ancient and had screws missing from the engine cowling. That plane needs to be retired.

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.

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

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.

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.
