Although you didn't ask, you might also want to be aware of the Liquids/Gels carry on restrictions. You can find the info on aa.com. Enjoy summer camp!!
Here's a brief summary (from aa.com):
Place all liquid containers in a separate clear plastic, zip-top bag no larger than 8 inches x 8 inches (20 cm x 20 cm) or is quart size. Items must fit in the bag comfortably so that it closes completely.
Individual liquid containers should be no larger than 3.4 ounces/100 ml.
Remove the plastic bag from the cabin bag at the security checkpoint for separate x-ray screening.
