The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

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

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

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

Put some new and several options for entertainment. Do not be rude to customers and avoid serving them an extra coke or something. We paid 1200 GBP for a return flight.. A noisy, crowded, rude and uncomfortable flight.

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

They lost my luggage on my way to Namibia (I was unable to review that flight as I was in the bush/off line) It took 3 days to get my bag and I had to pay $375.00 to have it transported to my location as it was over 100 Kilometers from that Airport and the local Airlink carrier would not got that far.

Great flight, last one out the air-conditioning was far to hot and the return it was to cold and then issued blankets. On the outward bowned the headset connector didn't work properly. You had intermittent sound from the audio socket.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Terrible service especially for premium economy. Much more comfortable seats on other providers

Friendly hosts/hostesses; dinner was of acceptable, but mediocre standard

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

It was just ok. Half the bathrooms were broke on the flight.

If they wouldn't have canceled the flight WITHOUT informing me until I looked at my ticket and saw I had 2 extra layovers in 2 different cities than the ones I paid for? That would have been nice.

Poor BA get a lot of stick and have some problems getting your bags to the same destination BUT the whole experience is very much 5 star and probably due to excellent, helpful and sooo British staff. We travelled in economy plus.

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).
