Who paid for the hotel?
From the EU Directive-
* in the event of long delays (two hours or more, depending on the distance of the flight), passengers must in every case be offered free meals and refreshments plus two free telephone calls, telex or fax messages, or emails;
* if the time of departure is deferred until the next day, passengers must also be offered hotel accommodation and transport between the airport and the place of accommodation;
* when the delay is five hours or longer, passengers may opt for reimbursement of the full cost of the ticket together with, when relevant, a return flight to the first point of departure.
Last time when my flight in AMS went tech we got either a shared cab or a hotel. had 15-20 EUR of food voucher. Since my ticket was HKG-AMS-HKG i suppose i could piss around and ask for a refund and return to dirst point of departure...
