Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

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.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

Plane was crowded, seats narrow, legroom nearly nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to repair it. This flight was in direct contrast to a very comfortable Lufthansa flight from RDU to Frankfurt about a week earlier.

I was extremely stressed out with the delay of our flight, not because of the delay per se, but we weren’t getting any responses from the staff/crew as to what was going to happen with our connecting flights. I think if they were better informed, and in turn we were informed, we would be more at ease. Also, at the Newark security area, the scan machine detected something “foreign” in my crotch and behind area, I cannot believe that in 2024, these machines cannot differentiate between a sanitary pad and a dangerous object. The security officer who conducted the body search was really sweet and apologetic, and asked me if I would like to move to a private area and conducted the search thoroughly without making me uncomfortable, but it is clear that these machines need an upgrade for such issues.

Staff are really not attentive. Seem rather disinterested in attending to the customers in general.

Smooth flight. Safe airline. Professional crew. Glitchy entertainment touch screen. So-so food. So-so seat padding.

No one came to pick my mom up with the wheelchair

They delayed the flight multiple times, canceled, and then did not rebook or reserve hotel rooms

Boarding was one hour late. Gate notification was incorrect (notification said gate 17, actual was gate 14). Took shuttle bus to board the plane. Late arrival of plane at Turin impacted travel arrangements to the event.

Absolutely the most awful experience in the history of service from gate agents to baggage handlers. Never will i use kayak or Lufthansa again. Ever.

Would never fly lauffthabsa again. Seats were way too crowded together....very uncomfortable le

Very good- my first flight with Airbus A380/800. Some of the food was not tasty , however. Everything else was excellent- the crew, the comfort, the process.

The seats are incredibly uncomfortable. My luggage didn't make it on my flight from London to Nashville.

The seats were uncomfy and the food tasteless, crew clueless

My problem was with the onward connection between London Heathrow and Washington IAD. The flight was several times changed.

British Airways keeps canceling our flights. They have lost my trust in using their services again. I understand rescheduling once but twice? I am now arriving at home 36 hours later than the first flight that I booked.

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

Flight attendant kept banging her cart into my aisle seat. Hard. Couldn’t lean seat back. Should be warned of limitations when booking seat

I’m appreciative that the crews were polite. I didn’t eat the food due to my nutrition plan.

My flight was cancelled and I was rebooked onto 2 flights on American Airlines: one from Heathrow to Charlotte and then one from Charlotte to Tampa.

Disaster out of City Airport with our flight cancelled and very little help.

I’ll fly with any other airline. Besides all the fees and not being able to change a flight even to a later flight without paying £150 charge. Or that the last flight the WiFi didn’t work, the food was so bad, and ran out of options. Seat didn’t recline. And the headset jack didn’t work. This isn’t my first flight with them, and on every flight there is always something wrong that makes the long 10 hours feel like an eternity. Never flying them again.
