My experience with Scoot is very good. Will have no issue flying with Scoot again.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

All in all the flight was good. Love the fact that for airline food it was piping hot

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

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

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

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

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

I travel frequently. The flight was late again... KLM should really try and be on time

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

They charge me for luggage which is was included on the ticket

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

The line at boarding was not well organized and managed

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

Sky priority means you get to use the KLM business Lounge.

Je n'ai pas pû incliner mon siège et une des hôtesses ne comprenait pas ce que je disais. Je devais parler fort

Overnight flight in the old style Business class, but still very good.

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

seat didn't fold children noise in the air plain. no foot space

the worst experience we had. they put connection label to our luggages with mistake and we had to wait for 5 hours to pick them up

for the very long way the flight has to be more confortable it was very dirty the wc was not clean

COmpared to my experience in the business class of other airlines the food variety and offerings were meager. They did not have any cookies or crackers for snacking! They were unable to offer some other items. This has never been my experience in other airlines.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

I paid for reserved seats but didn't got them at all

Service was superb and the flight experience overall was great

The flight departed on time and the staff was professional.

Horrible. The plane didn't land on time. Again left delayed 1 hr. Then landed in different city Poznan. No one there was from Luthansa. We were dropped off like animals. No food, no instructions. After 2 hrs we got a bus! 1 bus for all the people from the plane. 4 hrs back to warsaw. Arrived at 11pm at the airport in Warsaw. Again No one from Luthansa. I had to sit spend a night at the airport to get a bus to my final destination in Poland. Shame on Luthansa!!! Will never fly in my life! Paying $1400 for the ticket with 2 delayed flights, nothing offered for inconvenience!!! Bad bad

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

The Lufthansa part was wonderful. The short connection flight was not.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

I wish the flight attendant was a little bit kinder

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

Very poor, flight cancelled, no help from Lufthansa customer service.

Very organized check in and boarding experience. Good crew very helpfull.

My incoming flight from Rome to Munich was on time. But part of the deplaning process is that we had to take a bus to the terminal. The layover time was too short so me and other passengers that were going to make the Munich to Diussepdorf plane were stressed. We all ran through the terminal and we got there right on time to find out that our plane to Dusseldorf was 15 mins late.

Great, the staff the service and everything was very good, without delays very comfortable.
