I've been meaning for some time to write about the CARES harness. If you're not familiar, it's an FAA-certified harness that children one and older (and between 22 and 44 pounds) can use on an airplane in place of a car seat. The harness weighs only one pound and easily installs on your child's seat. Despite constantly whining about my difficulties lugging TJ's car seat through the airport, I inexplicably haven't purchased one yet (I guess I need the airport workout). But, I've seen them in action and they look as effective as they are convenient.
The great Family Travel blog revisits an earlier discussion we had about car seats and air travel safety and poses an interesting new question: Would you pay a little more for your plane ticket to cover the airlines' expense in stocking their cabins with some CARES restraints for passenger use? I'll give my two cents over there, but my main point is that the cost would be incredibly minimal. If you have an opinion on the matter, please join in.
