My 80-year old mother purchased airline tickets, but she inadvertently purchased two for herself and two for my father. Interestingly enough, CheapoAir did not notice that the names, IDs, and birthdates were identical for them, and still went on and sold the tickets. Next day she realized that mistake so, within 24 h, requested cancellation of two of the tickets. Again, CheapoAir's wonderful "system" did not allow partial cancellation of the purchase, so they cancelled all 4 tickets. And, the big surprise, is that they charged a US$50 cancellation fee per ticket, resulting in a $200 "free cancellation within 24 h". DO NOT USE THEM!
