I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

old plane but clean and comfortable, very nice crew, LOT made excellent improvements in terms of quality of food served in the business class. really fresh , tasty and easily digestible, good choice of soft and hard drinks- good polish wines( white ones reds have way top go)

I have flown with LOT several times and regret it every time; however, they are the only airline that offers the direct flights I need. Boarding was awful. I was alone with 3 children, including an infant, and we were forced to stand in buses packed like sardines. Then, for such a large flight, there was not even a gangway. I was expected to carry a baby, a carseat, and luggage by myself up the dangerous steps into the plane while the crew RUSHED me. The crew was very curt, cold, and inattentive. No one offered any assistance or sympathy to me alone with kids. There was no ventilation or AC in the plane.

My ONLY complaint with LOT was the lack of WiFi and the food in business class… still, I use them because they have great connections to Chicago and they fly the 787 - which I think is a great wide body jet. Well… now LOT has WiFi (good satellite speeds) and AMAZING food. LOT now is giving Turkish Airlines a big big run for the money. And they consistently have less expensive business class. I am a very happy customer!

Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

Amazing crew, delicious food and drink selection. 12hr felt more like a 4hrs. Comfortable beds. Can’t wait for the new business class cabin

Flying business class saves you. Once you get out of the terminal and onto the plane, it’s fine. The traffic at the gate is a horror. No organization at all. The fact that Business class is promised early boarding is a myth.

The seat was paid for but given for some different person .

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

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!

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

Nice, it was nice to have a free night's stay because our layover was over 18 hours.

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

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

Service and food were decent, seats are a bit too narrow. Leg room is normal. Bathroom should be cleaned more frequently. WiFi is cumbersome and should be simplified.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

Good service, the airline also provided a traveling kit bag (tooth brush, socks, slippers, visor for sleeping).

Food excellent Bathrooms improve cleanliness needed Staff fairly well attentive Entertainment fair Seats lie flat worked well

Connection was a headache due to a delay on arrival flight

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

I had connection flight. I barely made it to the next flight. I had to run to get to the next flight which was far away from where my first flight was landed . On top of that they search my stuff before boarding that added to the time. Food was ok but they forgot to serve our row with drink and also when it was our turn, they ran out of second option for food and we didn’t have any options for food.

Starlink internet made the flight time shrink and I was able to work.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

The food could have been better and the entertainment could have better movies or streaming.

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

Bag got checked but I thought one personal item was guaranteed.

The seats are very small, that is all the staff did a good job.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

After flying on Icelandair to England and getting a greeting glass of champagne, free drinks and salmon I returned to the US on United for around the same price and got told immediately that I would have to eat a vegetarian meal because everything else was gone and every time I paused thinking in flight entertainment I got advertisements on the screen. On the Icelandair flight I had a great selection of documentary films and on United I was reduced to watching the Spider-Man movie. Guest which airline I look forward to flying again?

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Inflight food quality is definitely declining. Only one hot food was served and rest of were boxed meals. That’s not how was done before. Better to fly Asia or Qatar carriers for better service.

The seats on Lufthansa’s international business class on the A350-900 is the worst product in the market. Our chief purser was AMAZING though. She is the best FA I have had in many years.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Never happened. Flight was delayed. Had to be re rojyed

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I was very happy with everything, thank you for the smooth flight ✈️
