Appropriate age group:
Infants
Toddlers

Description of tip or technique:
The child may be safest in the infant seat, but if you got "under 2, rides free" booking, that may assume the child will be in your arms if the flight is fully booked. Even if not an issue on the airplane, it could be an issue on shuttle bus or other mode of transportation.

Other comments or suggestions:
Ask for Details when booking any form of transportation with Baby; at least that can help to make informed choices.
