A successful trip with your children begins before you book your flight. Air travel is hard enough when everything goes right, so don't open yourself up to delays and other major changes at the last minute. Whenever possible, choose the first flight of the day to avoid delays and missed connections. Booking nonstop flights is key when traveling with an infant, while a short layover allows older kids a chance to stretch their legs. Above all, allow yourself plenty of time for traveling to the airport, parking and getting yourself and your children to the plane. Knowing you have enough time for extra bathroom breaks or unexpected diaper changes can ease stress and make flying easier for the whole family.
