Can 15 year old teens fly alone

Yes any kid can fly alone when you buy the ticket u will need to mark 0 adult traveling.. You will be asked if you want Unaccompanied Minor Service check yes.... It is only available to kids ages 5 through 17 years old, on both domestic and international flights.

I would contact the airline and the airport if this is possible. .

Contact your airline about their unaccompanied minor policy

I think so
