Before I buy tickets on Airtran for our Feb, 2013 trip to WDW, I'm signing up me, DH, DD, and DS for A+ rewards. I understand that everyone has to have their own account, even minors. When I attempted to sign up my son, who is 16, for the program, I get a message that says to contact Airtran when trying to register someone under the age of 13, and gives me a phone number to call. This is after I filled in all registration information, including his birth year of 1996, which does not make him under 13. Has anyone else had any luck signing up minors for this program online, or did you have to call Airtran?
