I have only used this service once. When I was 18 Vanguard airlines was having a sale for $29.00 airfare one way from chicago to buffalo and vice versa. I was young, with no credit card so I went here, they let me give them cash and they put them on their credit card. They only charged me 10 for the round trip. (As well as two other friends who did the same thing) and we had a heck of a trip. They helped me out when I was in a bind and I really appreciate that!
