Any child under the age of 15 must be on the same reservation as an accompanying adult
I would assume rules differ for any international travel.
also keep in mind frontier won't give hotel vouchers even if they strand them during a connection or divert.... and hotels won't check in minors without an adult
So, what this means is basically Frontier is treating 15+ passenger as an adult and allows a passenger under 15 to travel with that individual even if that 15+ yr old is not an adult (over 18). In our case, the flight is a nonstop and so that minimizes the risks of being stranded, which would only be under extraordinary but unlikely circumstances such as emergency, detours, etc.
Thank you very much for your prompt response, much appreciated.
