no they don't. I think that if you want your kid to travel alone, you have to hire a person that can accompany them to the airplane, and take them to whoever it is going to pick them up at their final destination.
Yes, but this is typically handled by the airline(s) and may involve an additional fee.
Depends on the airline, but united airlines does
I agree with Gladwin. You should ask the airline immediately.
