Unbelievable ... Keep in mind, I am an employee!!!They flew my 13yr old daughter to Wisconsin ... Unaccompanied, from our home in PHX with No Issues. When her mom brought her to the Appleton Airport (the same one she arrived at), 1 week later, they said they had a technical issue during booking, and could not fly her back on that particular flight. We rescheduled for later that day ... unfortunately, they booked her on a "last flight", and because I am an employee, she is stand by ... Unable to board. So then her step-father brings her to the Delta Counter Yet Again, the following day ... (now missing school after Spring Break). Now, Due to Company Policy, She Can Not Fly As an Unaccompanied Minor!!! They Flew her There, They Rescheduled Her return flight 3 times, and Eventually Said they will Not Fly Her Back Unaccompanied!!! Despite Flying her There The Exact Same Way!!! My 13yr old Is Stranded By Delta!!!
