http://www.ajc.com/travel/avoiding-the-pitfalls-of-1012835.html Sending your child on a flight alone can be overwhelming for a parent — from packing the right things to making sure the kids are fed. Adding to the confusion, not all airlines follow the same rules, or charge the same fees for children flying solo. Yet hundreds of thousands of kids fly on their own each year — about 160,000 on Delta last year alone. Delta was the world's largest airline in 2010 before being displaced when United and Continental combined. Here are the general guidelines on unaccompanied minors and some do's and don'ts to avoid problems at the airport. Booking Reservations are made the old-fashioned way: by calling an airline or travel agent directly. You won't be able to book online, but you should still research flights online before calling. Airlines should waive an additional phone reservation fee in this case. Check with the customer service representative about that.
