Beware: Hidden fees
It takes forever to get through to their call center and they have the most irritating waiting announcement, I gave up after half and hour waiting and getting a headache. Please note that they will process your credit card payment in the Netherlands which will incur a cross border fee on most credit cards. This is not stated anywhere on the web site. So you book a ticket departing from SIN in Singapore dollars on .sg web site but the payment is not acquired in Singapore. Nice surprise cheaptickets!
