Unaccompanied minors flights on delta airlines have been a success several times. I've flown my kids from Frankfurt, Germany to NYC or Detroit non-stop several times and not had a problem.
The angry posts from other customers seem to be misplaced. The Delta airlines website is very specific about what is, and what is not, allowed. Mistakes can happen when booking tickets as agents don't typically book unaccompanied minor travel all day long. I make it a point to repeat details about their age and travel times to the agents to avoid the problems others have.
I also kill the customer service with kindness as I've learned they are yelled at by angry people all day long. Why?
Because no one calls them to just say hello or good job! Someone who calls in with a problem and remains calm while being demanding is going to get further than someone being a ***.
