Before your flight, make sure you talk your child through all the steps in the airport: checking luggage, security check, and waiting to board. On the day of your flight, arrive early to leave your family plenty of time to make it to your gate. Depending on their age, you may allow your child to be responsible for their own luggage. Have your items prepped for security, including electronics accessible so you can remove them with ease, and liquids in see-through, TSA-approved bags. Finally, be aware that many airlines offer early boarding for families, saving you time in line; do your research, and see if it makes sense to book with an airline that offers this benefit.
