<p>I see that the term used above was “minor flying alone,” which may have been intentional. I think it’s important to avoid the term “unaccompanied minor”–as that generally leads to extra fees/restrictions. It’s an optional label for kids between the ages of 14 or 15 and 18, and using it requires a level of supervision (and expense) that most of us are trying to avoid. When we’ve had difficulty with connecting flights, I’ve avoided any terminology at all, simply told the agent my kid’s age, and they’ve been very helpful.</p>
