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

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.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

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.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

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!

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.

Crew was excellent. Business class was poor on the short flight and mediocre at best on the international flight.

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.

The flight itself was pleasant and on time. Crew was very good. However, breakfast food was barely acceptable. Unfortunately this satisfies the recent industry standards. I asked for a sandwich with ham (another choice was cheese), but received a sandwich with roast beef.

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

Delay rushed to the next plane and bags didn’t arrive in chicago

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

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

Checking in took very long for whatever reason. Flight comfort these days is always poor so… Crew was great thought!

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

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

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

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

The service and flight was great. Luggage came out very quickly!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

Basic, 737 Boeing, business class is just an economy class seat with blocked middle seat (European standard).

Entertainment is nonexistent. Food might have been good, however due to language barriers I didn’t get to have any food. Flat bed seats and layout was excellent. Crew efficient and straightforward, but lacking any western style approach. Not that I’d expect anything else, but one could have hoped.

Unorganized, late and they lost my bag for several days.

Flight took very long to even get checked in for, everything was late and written out by hand. My luggage was lost for several days and it was the most unorganized flight experience of my life.

Delaying more than 5 hours from Belgrade to Tirana Information very rude to questions

It's the shortest trip one could get from BEG anywhere, so it was fine.

I paid for luggage when I bought the ticket but I could not board until I paid for luggage again. The fault lays at the feet of eDreams, the company that booked our flight. Sorry, Air Serbia, but it did affect the boarding process.

They had lost my ticket and despite showing them the confirmation email with the itinerary and receipt of payment for the flight they could not put me on that flight and rescheduled departure postponing it by a whole week

Kraljevo is very convenient airport. It's brand new, small.and efficient. Great job!

Long delay (6 hour late departure, not informative enough to provide up to date info on flight, poor food quality
