Brand new plane lots of room the snack was very flavourful and enjoyable

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on 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 left a few minutes late, but that's it. I wish the seats could be wider and recline more.

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

The whole trip was excellent. The only thing I would change is the temperature of the plane was a bit high which made it uncomfortable to sleep.

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.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

It was nice to be on a legacy airline, people try at least.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

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.

Food was terrible. Crew was kind but skipped over my row for providing sandwiches and beverages.

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

Liked nothing. As per previous segment it was delay delay delay.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

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

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.

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 🇨🇦

Cancelled - booked on train; and then flights started running! I spent 5 hours with 2 changes on train while flights started and is 50 min

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.

The real bathroom smelled horrible and it smelled in the real of the plane..

Well the flight was 3 hours delayed taking off which lead to missing the next flight in Newark and an overnight stay in a hotel (at my expense) for a next day flight, 1.5 hour long immigration line, etc. Let's just say my travel experience wasn't pleasant.

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

We were helped whenever needed and had a pleasant flight.

Le personnel attentionné et trilingue, la tranquillité du vol. Aucun aspect négatif

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.

Poor food choice. They even ran out of fish in business class. Old dated planes, IFE and seating.
