4.0 Mediocre
Cons:Crew members in Amsterdam were very rude and disrespectful
A
4.3 Mediocre
Pros:Friendly crew
Cons:KLM lost one piece of my luggage
A
2.0 Poor
Cons:My girlfriend were scheduled to come back from Marrakech together (albeit on separate reservations), however KLM could not find her reservation in their system and would not let her on the plane. I had to leave her behind in Marrakech. KLM had the audacity to ask her to purchase another ticket, even though she clearly had a valid reservation (how else would she had gotten to Marrakech in the first place?). After arguing with KLM for many hours, they finally booked her on a flight the following day, but refused to put her up in a hotel for the night, or compensate her for the trouble. Completely irresponsible behaviour from KLM. Will never fly with them again.

A
2.0 Poor
Pros:He missed it due to having a 32 minute layover, which he ran all the way to board.
Cons:he had no choice but to look at the closed door of his flight, and wait an additional 7 hours and they didn't even give him a voucher for food. I'm his mother, I'm currently visiting family in Scotland, so couldn't help him much. I'm pretty disgusting and disappointed by the whole experience.
