Good flight, loved the snacks (Biscoff cookies). For boarding, they forgot to change the sign showing our group was boarding. Apparently, they had announced it, but the announcements overlapped with another gate announcements and no one could actually hear what they were saying. So a group of us were waiting....and finally asked and were told we could board.

Good flight, loved the snacks (Biscoff cookies). For boarding, they forgot to change the sign showing our group was boarding. Apparently, they had announced it, but the announcements overlapped with another gate announcements and no one could actually hear what they were saying. So a group of us were waiting....and finally asked and were told we could board.

overall no call for accessible while boarding. The crew member was little rude not bothering about the condition. Seat assigned was very uncomfortable.

Check in & bag drop was straightforward. Alaskair changed the gate approx 40 min before departure, and I only became aware due to Google wallet update to my boarding pass. Had to move from gate N1 to C9 which required use of the Train, luckily I had time available.

Flight delayed no communication. The gate was changed so many times.

I wasn’t aware that we needed to supply our own screens for entertainment

I was standing in line to use the restroom. A First Class passenger wanted to use the restroom after me, but Jaques made me wait on Flight 3418 from BOI to SJC on December 12, 2025. I felt this was inappropriate and rude.

Look at my previous review I just wrote on this survey. It was awful!

The airline staff was great! The best safety review ive ever had!

Hawaiian Airlines, like most US-based ones, constantly provide sub-par service and pack their planes to the max with all kinds of last-minute-purchase schemes. As a result, it makes every flight so uncomfortable and generates high health risk for its passengers. In one word, GREED rules the day!

generally good. No snacks or drinks on the flight 3379 from Portland to San Jose, CA. Sad.

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

The cabin temperature was nice and cool. The wifi was not working.

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

They double booked seats, the gate staff changed my ticket as I was boarding she went over to the computer and changed it without telling me. She messed up an entire three row section for me and others. Other travelers were outraged but the gate staff were so rude, so condescending saying it wasn't their problem to solve. I would rate this a zero if I could. Will not fly Delta again I'll stick with United and American.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Crew was not friendly when I went to request a seat change.

Comfort+ on delta was excellent room for a 6’4” male. No one issues. Staff was great. Flight was bumpy but the pilot did everything he could to make it comfortable. Internet went out half way through the flight. I am glad I didn’t pay for it. But that was a huge issue for users.

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

Delays, excuses, delays, and more delays. This company is BROKEN.

The in-flight entertainment options were great. I always appreciate a seat back TV on a domestic flight. However, there were issues with a computer system that were discovered after we had boarded that caused repeated delays, and eventually we had to deplane. I liked that United texted me a $30 food voucher for the inconvenience, but it caused me to miss my dinner plans in West Hollywood that night. Once we were in the air, everything was fine though.

This flight 1810 on 7/30 from EWR to DFW got 4 hours delay. this round trip experience is bad, my AA flight 618 from DFW to EWR on 7/28 was redirected to PIT and totally delayed about 9 hours due to mixed of weather and AA IT outage and then on the way back delayed for 4 hours. Lucky, i changed my flight to UA on the way back. i don't like AA anymore. i will consider other airline options in the future.

Mechanical delay > Crew Time out. No communication to passengers. Crew time out was positioned as a surprise (even though it must have been know at the time of boarding that the crew would time out.

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

I don’t like the music section but I believe it was a cost decision. I changed my flight last minute due to work issues and had to sit way in the back. The seats were way closer together than I would have preferred.

The flight attendant was very polite and attentive. The food was good.

Wifi was spotty. Tray table was very dirty when I sat down.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

Nothing really nondescript, the flight attendants were friendly and helpful.
