I just bought alot. I need to purchase 2 tickets to Europe in the next few weeks so thought I would go ahead and try the gift certificates. Thank you for your information which relieved most of my concerns. I'll be sure to use the phone number on the back of the cert. Am I missing something? One or two certs would not buy a ticket. Why are people not buying enough to pay for an entire ticket? Is this because of a concern for the legitimacy or use of the certs?
