Compare prices at the major booking sites (Orbitz.com, Expedia.com, Travelocity.com) and the aggregators (we like Kayak.com). Once you've found the best rate, book through the airline's own site to avoid the middleman fees—with multiple tickets, these surcharges add up. Keep in mind too that you'll likely pay less by opting for second-tier airports—Chicago's Midway instead of O'Hare, for example—and by flying whenthe coast is clear (see "Traffic Alert,").
True, babies under age two travel free, if perched on an adult's lap. But according to the FAA, parents should shell out for an extra plane seat to prevent kids from getting tossed about during turbulence. The agency also recommends that passengers weighing less than 40 pounds be strapped into a child-restraint system (most car seats fit the bill—check the label for the government's okay). To simplify your schlep, consider a stroller you can snap your car seat into, such as Maclaren's Easy Traveller (rightstart.com; $75). Or for children 22 to 44 pounds, opt for an FAA-approved Cares harness (kidsflysafe.com; $75). It connects to airline seat belts and fits in a six-inch stuff sack. Mothers and fathers, rejoice: you finally have space to yourselves!
