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.

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

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.

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.

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!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

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

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Food seats were good Flight was delayed for over an hour, missed connecting flight, lot automatically rescheduled us to a new flight which was good but lost approximately 4 hours. Not a good way to start a vacation.

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

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

The seats are very narrow. Communication regarding bids for better seating could be better

During the flight, the fleas biting me in the plane.

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

The seats are small and the movie selection was disappointing. However, the food was excellent and the cabin crew was attentive and kind.

Plane is super outdated, seats not that comfortable for business class. Lounge also out dated. They need to catch up to 2024. Don’t think I’d ever fly again.

Aircraft was new. Food so so, especially vegetarian was very disappointing.

Boeng Dreamliner has so tiny seats, so even medium and smaller size people have not enough room to fill comfortable..

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

There were not enough extra leg room options to purchase. Also the seat Infront of mine was broken and the gentleman literally laid back into my lap for the whole trip. This was the most uncomfortable trip I have ever been on

A lot of things can be done to improve in flight experience

Average at every level . Poor entertainment selection. Boarding was very poor and disorganized. Flight was late by one hour .

Spent over $20k on for business class tickets from DFW. They used a very old Boeing 777 with old Business class cabin which was unclean and stained seats. On a route they normally operate the modern Boeing 787. The cabin heat was set to hot for 11 hours. On the IST LHE route the business class experience got even worse. They operate an even older Airbus A330 where trip was falling apart, seat recline did not operate and the whole experience left us hugely disappointed. Next time we likely will shift to better quality product which stands up to their hype. Turkish need to relook at their fleet plans and not use their worst assets of perceived week markets such as Pakistan.

The flight from Houston to Chicago was delayed, causing us to miss our connecting flight to Madrid, losing our Rental Car booking in Bologna taking alternative travel routes to get to our initial destination in Pizza by the 15th. We got the notification of the delay as we were traveling the 3 1/2 hours from Corpus Christi, Texas to Houston Texas for the initial flight. The delays hauling luggage all over Milan‘s Central train station to catch trains to get to Pizza the same day resulting us arriving in Pizza at 2 AM leaving us no time to rest as there was a 9 o’clock checkout time the next morning. The first 72 hours of the trip with nothing but headache, a knee injury from the excessive walking and a delayed car rental replacement, which ended up costing significantly more.

We flew business class and it was impressive. So comfortable with delicious food and very attentive and polite staff. Will definitely fly Turkish airlines again.

To get to jet blue at JFK from any connecting flight you have to go through security again.

Amazing! One of the best kept secrets in air travel!

We fly Bussines class and we didn’t feel like it is. Out luggage didn’t arrive and we have to return again next day from our hotel to airport to get them. Still waiting. No information from Turkish airlines Very poor customer service I think booking through kayak it was wrong decision

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

With discover in general was very good but from Munich yo Palermo was poor

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

Really delayed, no effort to support customers other than “sometimes we run late.”

It was serviceable, nothing special but nothing awful on this leg.

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

Polaris seat is plush and conducive to sleep. Cabin crew was experienced, highly attentive and helpful when any need arose, such as finding a lost phone in the seat mechanism. Food was a disappointment, especially the Japanese items coming out of Newark all seemed a bit overcooked, though the empanada snacks served midway were a hit.

Ridiculous boarding. Enter the gate, walk down a staircase with bags, exit a building, get on a crowded bus, dropped off a few meters away from the aircraft, walk with bags to another set of stairs to board the aircraft. And all that during a pouring down rain, and with children. Ridiculous!!!

Lufthansa no longer offers any refreshments and snacks on short i.e., around 2 hrs flight. We still had full staff stewards/stewardesses. No idea why they were needed as there was no work for them during the flight

The tv and remote didn’t work. The plug to charge our phone didn’t work.

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

The crew could deploy more customer focus and not frown when asked a question. I’m speaking of one lady in particular who raised a hand in my face for me to wait whe I tried to ask a question and never came back to me. Very unprofessional and rude.

They set someone on our assigned seats and we ended up finding seats for ourselves to ensure the family sits together.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.
