It costs less then $15 using some PVC pipe, and a thrift store suitcase. It looks and performs professionally. It's light weight with telescoping handle and nice roller wheels. It only takes an evening to hack together with simple tools. This really does make zipping though the airport with a small child in tow much-much easier.
Going on the airplane can be a pain. Stroller, car seat, diaper bag, a bag with snacks and toys. So much stuff! The car seat is especially bad because it's an awkward size to just lug around. I've often found myself dashing from terminal to terminal with one balanced on my head, or jabbing me in the side as we try to make the next flight.
With this simple frame, you can not only haul the car seat along as easily as a wheeled suitcase, you can also do it with your child strapped into it. Thus getting rid of the need for a stroller entirely. If you're actually taking the seat on the plane (instead of gate checking it in the case where the kiddo is going as a "Lap Child") you can even roll it down the isle of the plane. There's also the added benefit that the child is strapped in during much of the process, and at least my kids seem to love zipping around in the thing.
What's more our happy band gets lots of looks in the airport and people ask "where'd you get that?" and I get to say "I made it!"
