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

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

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

You should not have to pay for WiFi in business class

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.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

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.

All and all pretty good. It’s crowded but that is what flying is all about. But no complaints otherwise.

Good flight, clean, well mannered/respectful Staff, .food are OK. Affordable price range

Copenhaguen airport is not very efficient, signs are not clear enough. Too much walking.

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

Cheap business class has everything you'd expect except the large seats with good leg room. There was priority boarding, lounge access, great meal in-flight. Great value for the money, and I would do it again.

When leaving Florence the speaker at kiosk didn’t work and couldn’t hear directions. Then, at the layover at Copenhagen we all rushed to “board” as directed but were then quarintined in a room to wait with no food. Then we sat on the plane for hour and 15 min for a delay where they had to call a fire truck. My screen was broken on my second flight. Then we waited on the tarmac for a delay of 45 min on the plane again when we landed at Logan.

The quality of the food was 👍 excellent , I would have like to have in my meal : eggs and a protein bread, or dark bread , mayonnaise and a big cop for the coffee , cuz I am a coffee lover!

Excellent service, and came on time! Thank you for your dinner that was chicken with salat/, and 🍰 it was good quality food , the breakfast was very good with good cheese , butter,etc and the tea was very good quality. The space where I was seat was nice so I could stretch my legs. I dit not have the bread as I am in a keto died. Have great time everyone in Scandinavia airline.

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Seats weren’t comfortable Hard to adjust and seat in front was damaged and repaired with tape minutes before we took off Repair was best the repair man could do in the 2 minutes available but it meant stowage couldn’t be used Entertainment choices could have been wider Staff were very good

They canceled my flight and made things harder but they booked us on Air France but cancelling my flight late at night uncool bro

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

From boarding to disembarking, the whole operation was very efficient.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

I forgot my headphones in the plane, how can I retrieve it?

Keep track of your departure times and communicate in Airport. I could have spend an hour more in my lounge
