D.S.
I second the Chicco Liteway! I love the fact that it has a harness as well as a lap belt because my son has a habit of falling forward when he falls asleep in it and that keeps him in better. (He also tends to throw himself forward when he doesn't want to be in the stroller anymore and the harness prevents that.) We've taken it on a couple of airplane rides and it has held up well. Plus, the little "basket" at the bottom doubles as a backpack.
