Since 4 July 2008 KLM, in cooperation with Amsterdam Airport Schiphol, has been offering self-service baggage drop-off to its passengers. The project started with a trial that included one drop-off point.The number of these points has gradually increased; as of 8 February 2012 there are 12 of them. KLM passengers can now drop off their bags themselves. Before they are allowed to do that they are being checked by a KLM employee.
