Maybe they are using MAS 90 v3.71??? It does say ""an older booking platform"". Damn! Even a $1B company like Orbitz cannot keep their systems up to date. Let's see, 880,000 credit cards X $10,000 per card X however many days they have been operating on a non-PCI compliant system = BANKRUPTCY! Any takers they just get a slap on the wrist? BUT, all you small businesses out there better mind your p's and q's!
