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

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.

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

The ground crew were helpful, although it was unclear when the ETA would be so we had to wait for quite some time before being notified of when we will board. Our seats were also changed, and there were also duplicated seat numbers which cost an issue when we boarded. When this issue came up, the flight crew was even Snarky towards us that we did not check our seat number when it was already reassigned. There were no apologies from the flight crew at all, and it was very disappointing.

Check in Agent at SFO was indifferent, didn’t say hello , didn’t place priority Tag . We were Travelling First Class. No foodas it’s a short flight. Still you could have offered some thing better than Biscuits/ Popcorn. They announced that luggage will arrive in 20 minutes after we reach the gate. First Piece came 35 + Minutes after I walked out of the Plane

Damaged my luggage. Insisted to check in my small luggage now it’s scratched and dented.

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.

No entertainment and one bag of pretzel/beverage at the beginning of a 5 plus hour flight.

The hosts were excellent !!! We had the BEST time. The pilot was great. Super great. Nicccce landing. Cheers. See YA’LL again sooooon.

My seat was broken and there was tape over the light/call buttons...but overall things were smooth

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!

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

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

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.

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

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.

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

Our flight was delayed several times. It left 9 hours after scheduling. We had to sleep in the airport.
