I'm not saying it was your fault but I thought to avoid issues like this BYU and most other teams went to almost 100% electronic ticket delivery. The only way to know for sure that the tickets are good is for the BYU Ticket Office to handle the transfer. They even partner with StubHub to ensure these problems don't happen. Some don't know that Season Ticket Holders are given the option to post their tickets on StubHub right from http:www.tickets.byu.edu.
There is a small learning curve but electronic tickets are awesome! No more buying the same printed PDF that has been duplicated many times over only to find out when you enter the gate that someone else with the same PDF got in first.
