£274 Find Cheap Flights from Costa Rica to London Heathrow Airport – Compare and Save

25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

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 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

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!!

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.

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

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.

The seats are too cramped in that plane. If you’re above 1,80m consider alternatives or first class I guess… There were no emergency exits to seat somewhere with more legroom

They lost my bag and I still have not received it

The food was great and the service and attitude was amazing!!

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

They lost my baggage and I still have not got it back. Disgrace

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Generally good. The crew is excellent. The food could be better.

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.

Food could have been better especially the breakfast. Overall it was a good flight

Flight was more then 3 hour late and I did not get my luggages

I paid extra for a seat with more leg room but they changed the plane and found myself in an ordinary seat. This is expensive at 50€
