Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

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.

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.

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!

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.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

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!

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Business Class was very comfortable and the food and service was top notch.

Seat very cramped, could not recline. No cheese with meal. Staff very helpful.

The flight attendants were rude in the DEL to FRA flight. The transfer between the two flights at Frankfurt International Airport was an unpleasant experience. The airplane was never parked at the terminal, but was deboarded instead on the tarmac itself. For those passengers in need of a wheelchair, it was a nightmare to come down the stairs and then rush across the airport to catch the connecting flight from FRA to IAH. Upon arriving at IAH, it was informed that the luggage had not arrived. Would make it a point never to travel with Lufthansa again.

The airport crew and flight crew did a great job rearranging the gate at the last minute and got us to Munich on time

No leg room! Either too hot or cold with these guys!

Great crew dealing with the most unprepared family with a million kids and zero sense.

They gave us free up grade to a roomier seat.

Flight was late, with scheduled 50 min layover at Frankfurt. Arrived at gate A54, had to get to B5. We now had 35 min layover with delay, at top speed it took 30 min to get to B5 hot and bothered. Not good. Boarding in Lyon was normal chaos, shoving, and total disrespect for anyone beyond group 2. Boarding for Milan flight was more civilized as we all had to take a bus to plane.

Prompt, efficient boarding. Clean aircraft and knowledgeable crew. Everything on time.

My first two flights were late. I missed my last flight. The next flight was not until the next day Seating on large plane was uncomfortable. In the center row, there are posts that do not allow you to spread your legs. The entertainment center did not respond well. . Food was okay. Though there was much confusion about where the special meals that. People ordered(not me) went
