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

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.

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.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

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.

Klm start boarding while somw air issue in the plan

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!

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.

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

Very poor. Seats like economy class, food unbeatable, no charging, no entertainment, no WiFi, boarding by bus - no justification for calling and pricing this as business class

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

Boarding could've been improved a bit, the rest is excellent.

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

Bags lost no more to say, bad communication and no urgency to get it back to the hotel by the airline properly the worst airline I have used.

0lane 2qs on tim3. Very bad food. No free wifi, only for texts. Entertainment poor and hard to access.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

My experience was wonderful. The professionalism of the crew was exemplary 🙂. The meals were wholesome and tasty. I have no complaints

Everything was smooth and great. I didnt like that they talk so much on the interphone during the flight.

Food used to be better and comfort was not attainable after 5 hours everything starts hurting.

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

The seat space seemed small especially when the person ahead reclined but other than that, very good.

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

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

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
