I asked a question earlier about using the CARES harness, and I'm still deciding, but one problem that I realized when we flew last time is that when we FF my daughter in her Scenera on the plane, the harness is below her shoulders. When she RF in the car, this isn't a problem, but it's at the highest it can go. Is there the same sort of restrictions when flying since generally you aren't worried about impact as much as turbulence? Thank you!
