I second the Volo! It s awesome for airports! I love that it has a strap if you have to carry it on your shoulder while carrying your child. It also is taller than most so you aren't hunched over pushing it.
Don't waste your money on a cheap one. You will use it a lot once you have it. It's especially nice for quick trips where you don't want to deal with the cluncky big stroller.
