I purchased in April 2008 HKG-AMS-BCN-AMS-HKG from klm.com for HKD$7294non-refundable discount fare, and checked today now priced at HKD$5916, a fare difference of HKD$1378. Approx USD176. When I called to KLM at HKG to inquire about possible refund of the fare difference. The klm agent said no way. This is my first time buying from KLM. I know for a fact that most US carriers, inlcuding NW, will refund the fare diff, or at least in travel credit. Is this common practice for non-US carriers?
