The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Empty seats next to me - wish it had been for a longer flight!!

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

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.

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!

OK overall. Flight was delayed Crew on flight was good

Late late late. Delayed and arrived an hour late for a 1 hour 45 minute connection. Every time. Poor record for this company. I try to fly any other carrier first.

This was the smoothest flight I've ever taken with any airline, including Aer Lingus. Typically, there are moments when I feel afraid, but from take off (miraculously seamless!) to cruise, to landing this was a perfect flight. Thank you!

Poor. Plane left EWR late hence missed connecting flight in Dublin. No pro active info from flight staff on connection, only when probed a couple of lies on where we would dock, and on lilelyhood catching connecting flight. Lies as they will have known our EWR-DUB would be parked furthest away from the transit spit - lying it would be next to the AMS flight.

The crew was friendly. The plane was comfortable. In-flight wifi didn't work well at all. The ride was quite turbulent but understandable given the weather.

I flew economy class. Seats were very good and the crew was excellent

There was a 6h delay with limited updates . When we got to Manchester the bus took ages to get to arrivals and we missed our train, dinner reservation. Basically lost a whole day due to arrivals Lingus!!

Great. Has a problem with DOB. Fixed 4 us. Led to a 5 hour earlier flight to London!

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

Flight crew was superb. Meal was one of the meals at altitude I’ve had
