There is a new website
http://www.euclaim.com and apparently a desk at Schiphol airport that will assist passengers in claiming compensation when flights are delayed or cancelled.
They work on a "no cure-no pay" basis, taking 27% of the paid-out compensation so it's probably a smart business initiative.
Especially if you don't have time yourself to deal with the claims.
I haven't seen this anywhere else - does anyone have any experience with these people?
Their website will include detailed info about flight delays/cancellations from AMS.
I am sure the airlines won't be pleased...
