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.

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,

As always, it’s a pleasure to travel with KLM. It is one of my favorite airlines.

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.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

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.

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.

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.

The pre-order only approach for fresh food is really challenging

the seat has a problem. the back had a hole.

The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

The seat that I got this time is really good.

Excellent flight. On time. Great staff. Clean and crisp cabin.

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 ✈️

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

This was the best carrier, comfort, service, good food, on time experience on a long haul flight. New, clean, quiet, smooth aircraft!!!
