Sometime over the past month, Tiger Airways has instituted a fraud protection system that effectively shuts out credit cards issued in the US. CRs at Tiger refer me to Visa, Visa refers me to Tiger. "Verified by Visa" registration makes no difference. Transaction shows up as "declined" at Tiger, but no record of transaction at all at Visa. MC similarly declined. This incompatibility makes it impossible to book a seat online, and makes this a useless airline for me.
You'd think they'd figure this out.
