Sorry, I was just passing along what I thought I remembered seeing posted here. Perhaps that poster wanted tix Fedex'ed and the rules are different for that versus airport pickup against a physical card and signature.

My personal experience with them was during the price-increase push a year and a half ago when they were accepting c/c's and Fedex'ing for free, and a later email exchange regarding non-OWE ticketing. In that latter case they certainly offered wire transfer as the only payment option, but again it for Fedex delivery.
