How do you take a baby stroller and car seat on airplane?

Baby strollers are usually treated as "gate checked luggage." This means that you bring the stroller through security and use it to carry you baby until just before boarding the plane. The gate agent places a tag on the stroller and gives you a stub, you leave the stroller in the jet way for the airline personnel to load as luggage and retrieve it at your destination as you walk from the plane to the terminal. Car seats that are FAA approved may be used in the plane cabin, otherwise they are checked as luggage before entering the secure area of the airport.
