PaulaMurf, nowhere on the ticket does it say anything about being a Southwest employee.
As for ending up on the Southwest Airlines Web site, I have no idea how you did that. You click on the link on page 4 of this thread (commerce4adventure) and you're on the order page for Sea World .. You have to follow the instructions in that particular message EXACTLY. (I didn't, the first time, and the code did not show up).
