Britax Frontier 85 v. 90

Is the only difference between these two that the 90 is the newer model and can last a kid an extra five pounds?

You can compare them on the Britax website.  It looks like the 90 as a couple extra features.

As of right now, the 90 is not approved by the FAA so you can't use it on a plane but the 85 is approved. The 90 has a half inch higher harness height so he can stay in the 5 point harness for half an inch seated height longer which for a 6yo is a long time.
