I m sorry to inform you all but KLM is the worst ever airline company.
If you are about to buy a ticket from them please DONT.
If it happened to you that you are already booked one DO CANCEL it.
It s for your own good and safety.
They r unbelievable, just google the reviews on the internet than you can have and idea of what I m talking about.
I m not gonna write what they ve have done to me, because it s still very painful.
