Flying can be a practical travel solution if you have children. You can trade hours of over-the-road miles for a relatively quick flight with a convenient restroom and sometimes even an in-flight meal. Concerned about safety? The Federal Aviation Association, or F-A-A, doesn't require car seats for infants, but many airlines will provide an F-A-A-approved seat for infants. Most airlines require these infant seats to be used in a vacant aircraft seat, rather than on a parent's lap. Airline policies usually prevent them from being used near emergency exits, too. You might consider using your child's personal carseat on the flight. Keep in mind that when safety seats are used in separate seats, a regular child's fare generally applies. Some airlines allow children under the age of two to fly free when occupying an adult's lap. Airplane travel can be an exciting adventure for toddlers and children, but their ears may be sensitive to altitude changes. Allowing a child to chew gum during ascent and descent may aid in equalizing the pressure in their ears, relieving discomfort.
