Empty seats next to me - wish it had been for a longer flight!!

Empty seats next to me - wish it had been for a longer flight!!

Terrible last row seats many seats available but no offer to move to better seat

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

Stuck on a plane for 6 hours due to a technical or mechanical issue.

Horrible communication, flight boarded then we sat on plane for almost 5 hours as the runway was barely covered in snow with no plows in sight and the as we tried to taxi there was a major equipment failure due to poor push off technique causing all passengers to be taken off the flight to ultimately have the flight cancelled. There was barely any communication to passengers as to what was happening or what to do next to get placed on another flight. Arriving to my final destination a whole day later having to take a connecting flight through Lisbon to ultimately end up in New York instead of a direct flight as none available for the next day. Never flying LOT airlines again!

Boarding was a madhouse. Airport staff was completely disinterested in communicating about the delays. Never again.

Smooth flight, excellent crew and good food. Not enough space; sitting are too small.

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

Very poor. Seats like economy class, food unbeatable, no charging, no entertainment, no WiFi, boarding by bus - no justification for calling and pricing this as business class

Boarding was delayed for an unknown reason for more than an hour. While the airplane was at the gate, the boarding time was moved by 10-20 minutes every 15 minutes. No entertainment on the plane.

Agents helping disable person doesnt know connections to Poland and after 9 agents helping and 2hours ,we made it to proper terminal. Polish Dreamliner its Polish nightmare liner with so narrow seats and no room under front seat for bag and feet,in economy class.To upgrade, to higher standart cost an arm and leg ,even there are empty seats No good experience overall

Horrible Flight significantly delayed. Not due to united issue. But trying to rebook connection flight and get information about overnight accommodation was difficult. Agent did not seem to care or have any interest to help.

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

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

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.

Reliable, nice crew, I fly often on that flight and I like it all.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

The crew on this flight provided exceptional business class service to me.

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

You charged me for luggage although the airline does not- you charged me for seat when customers can pick their own seat at checkout in I travel to Europe slot and I will not use kayak again

They oversold the tickets by one which was my ticket so I didn’t have a ticket till last second

Not good. I was supposed to be in Mint but got in economy class

Requested food options were always finished. Supplied food items were good but of course not the desired choices.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

Very bad experience with turkish airline tk 0001. Very uncomfortable seats and food ran out and crew was not helpful

The airline could improve its business class seats and privacy in line with its competitors.

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!
