I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

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.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

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

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

Not great - seats were very narrow and food was terrible.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

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

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!
