We left about 30 minutes late due to ramp issues. It did not impact me, but I know others on the flight had very tight connections to Maui.

We left about 30 minutes late due to ramp issues. It did not impact me, but I know others on the flight had very tight connections to Maui.

The stewardess are very nice and pleasant, Someone onboard had a medical attention, and they attended that person non-stop all throughout the flight, and yet, did not forget to serve and help other passengers.

Everything from the time I booked my flight through to the end when I got home was smooth and wonderful. Service was great, the flight attendants were attentive and there were no outstanding delays.

The staff was extremely helpful and accommodating. The only thing I could have done without was the long layover in between flights but I was going to a less popular destination so it was understandable.

Flight attendants made this flight wonderful. They made sure everyone had what they needed and anticipated future needs. They made adjustments as needed. It was clear this was an experienced crew.

Worst first/business class I have ever flown after 75 years on planes. Barely acceptable seats, terrible food, uninterested attendants, unavailable WiFi. I’ll never fly this airline again.

Delayed and no entertainment? I also forgot my headphones and immediately reported it and have not heard back yet.

Very delayed for seemingly no reason. Made me miss an event

All went well, right on time, easy boarding. We ordered the evergreens grain bowl and were surprised and pleased how adequate it was for vegan lunch! Landing was smooth and gate exit was easy

My seat and tray were filthy. Someone’s used straw was in the seat pocket and there were coffee stains and food crumbs on the tray table

Timing, quality of service, promptness and courtesy of the staff

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Very convenient considering that is a non-stop flight, but the Aeromexico still has old model planes, so the entertainment was very poor and the space for carry-on luggage was very limited.

Flight taking off must have been behind, because there was no pre-departure drink for first class like normal. Also, person in front of mine’s seat got stuck in the as far back as it normally goes position for the whole flight even during landing, flight attendant unable to fix it. Gate was not empty when we arrived, but that is MSP’s fault since was overdue for push back, not Delta’s, so had to sit on tarmac for a while and international flight so then still had to go through customs. Flight crew was excellent throughout though!

Flight from MEX to ATL had to divert to Tampa. When we got off the plane, there were non directions on what to do. Nearly 30 minutes just standing around. Finally told to go through security with no boarding passes, and turned away. Then told to to go back. Took forever to leave Tampa for ATL. Missed my connection to Harrisburg.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

This Japanese airline provides great service and very helpful in assisting their passengers.

Good crew. Boarding delays. Almost two hours wait for the bags in DC.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

It was a pretty standard flight... until the almost hour and a half spent on the taxi way. I get that the weather has been poor but the delay had nothing to do with the weather and more to do with a plane with several issues tying up the gate. I get that that happens from time to time but this has been EVERY flight I've been on for the past 5 years and I fly 3 to 5 times a year. This isn't just United... it's American, it's Delta. It's an issue with the entire industry. I work for UPS and packages on a cargo plane get better service than people do these days. Anymore I HATE flying.

I so appreciate the crew members on each flight of United. They are outstanding.

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

Flight was canceled. I asked to be rerouted to OKC and then took an Uber.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

On time on a day with lots of weather cancellations on other flights. Thank you for getting me home during a winter storm!

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

We were upgraded to Business Class. So comfortable with great service and food options

The flight attendant use 1.5 hours to answer my call. My dirty food tray was unattended.

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.
