The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

Terrible last row seats many seats available but no offer to move to better seat

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!

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

The Crew have no idea about the food they're serving the passengers. The Crew MUST be instructed before each flight about the menu that will be served to the passengers, whether the food is vegetarian or non-vegetarian, whether it is Halal, Kosher or not.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Was a good flight. On time. Was full and all went well

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

The in-flight entertainment options were great. I always appreciate a seat back TV on a domestic flight. However, there were issues with a computer system that were discovered after we had boarded that caused repeated delays, and eventually we had to deplane. I liked that United texted me a $30 food voucher for the inconvenience, but it caused me to miss my dinner plans in West Hollywood that night. Once we were in the air, everything was fine though.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.

If other people in flight, followed instructions and were much cleaner.

Everything but the food was top notch value for the price

Flight was delayed twice which made our arrival extremely late (actually into next day). Not an easy travel. But when we requested assistance for boarding we were really impressed with how they helped us! Strongly praise their assistance.

Flight was canceled due to labor dispute. Their customer service said I might be ok since strike was on sat. and I was flying Friday. The next morning it was canceled. It can ruin a trip and add stress.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Everything was excellent. Just keep doing what you are. I would travel with this airlines gain.

Flight was good. Really appreciate the second hot food offering. C

The chairs were too upright, but not awful. Boarding was fast and efficient and we did not sit too long in the plane before takeoff.

I didn’t realize booking through Kayak the pricing was in American fees and that I had to pay for my baggage when I arrived at the airport. I thought it was included in the price. For this reason I spent an extra $500. Next time I will book directly through the airline.

Kayak changed my Dublin flight and then changed it back to the original time before I left for Ireland. Unfortunately Kayak never booked me back on the original flight so when I got to the airport I had no flight to London. Very stressful. If I hadn’t gone very early and Aer Lingus staff so helpful it would have been a very wasteful day.

Everything was very excellent The food was great The crew was so nice 🥰👌🏽 I really appreciate and loved travelling with Air Canada 🇨🇦

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

Must deplane and take bus in Frankfurt. A big hassle.

We were helped whenever needed and had a pleasant flight.

Boarding was slow to begin. Economy board should be accomplished from rear of plane to front, as the entrance doors are front of plane. This would eliminate waiting and passenger congestion on the plane. Meals were good however crew will not check if you want meal if sleeping, should be like Emirates and give seat tags wake for meals or do not disturb. Entertainment ok but screen headphone/jacks were distorted - took 3 sets of headphones to get working properly. Flight crew was amazing, exceptionally nice, professional, best Lufthansa crew I have experienced.

Flew business class, flight on time, crew excellent. Boarding a bit chaotic...unsure why groups 1&2 board together and not one group at a time however an issue on all airlines. Designated lines would help.

Food was mediocre. In flight entertainment lacked live TV. Crew was fantastic. Plane very comfortable if a bit worn.

The check in was not good. I was unable to check in on line the previous day. I was rudely informed that I was late checking in and I was on standby. My husband and I were separated on the eight hour flight. It was very difficult to travel so long away from one another.
