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.

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

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

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

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

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

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.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

You need to make signage at Berlin Airport clearer. Having checked in online we had our boarding passes onlour phones. You do not make it clear that you need to check in again to receive a printed luggage tag. You get to baggage drop off and it says you can only do it with a luggage tag BUT not how to get this.

It was good except they could offer free water and tea/coffe

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Boarding and disembarking were smooth. Not offering free water was cheap ... I've never encountered that before on a flight.

Boarding could be better. To get through your gate but to be stood in a corridor for 20 minutes is not great.

The plane was postponed for over 2.5 hours, which meant that all four of us missed the check in time for our ongoing trip to Melbourne. We had to buy new tickets for 4 people as we had to forfeit the ones we had. The cost was really unfair. i understand that it was snowing during the first leg of the plane for that morning. Surely the cost could have been shared by the airline and not all by us. I could have bought insurance - but you can see how much I travel. I will need to chose more trustworthy airlines.

The true is that travel from London to Faro on 11/12/2025 by BA was cancelled, so I did not go to Faro, so i did not board easy flight. The mediocre qualification to you was because even when i bought an insurance, i could not change date neither obtain reimbursement. It could be ideal if you do something in order for me not to lose the purchase Thank you
