Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

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.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

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!

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.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

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

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Flight was good, boarding was a breeze, flight attendants were friendly and professional. There was a medical issue with another passenger and the crew handled it in a calm and professional way.

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the price of premium class ticket paid, felt more like steerage.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I had a great flight. Everything went smoothly and the flight arrived early.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Equipment swap led to 2+ hour delay on international flight. And to top it off, boarding took forever.

Wretched scheduling - they got themselves into a critical crew situation and didn’t try to address it until 15 minutes before they had to cancel my flight

They cancelled two flight and got us onto another airline, which was also delayed.

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Terrible legroom, seats do not recline, tray table the size of an iPhone, delayed flight, have to pay 5$ to get a cup of water onboard.

Could have TV/Movie and some water ou soda free

Flight was good and clean but delayed over an hour on the return flight.

The non stop flight and able to go into Atlantic City airport. They could lower the prices. It starts out low but then if you want to bring luggage and pick your seat the price goes up quite a bit.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

We can’t predict circumstances like this ahead of time, but I give your staff a hats off for immediately giving us updated informations.

It was nice! There was a very unhappy child in front of us and the flight attendant did a great job calming the child. I was impressed.

The plane was not on time for boarding or departure or arrivals.

EVERYTHING WAS WONDERFUL HOSPITALITY THE HELP.THE SEATING FRIENDLY ALWAYS HAVE A GOOD RIDE NOT ONE BAD EXPERIENCE WITH THEM

This was the smoothest flight I have had in awhile. I was also offered an exit row seat for a great upgrade cost and was able to sleep almost thr whole flight due to comfort and a smooth flight. We left on time and arrived on time.
