What do you think? Our LO is 10 months old, 16.5lbs, 28.5 inches long. She usually rides in a True Fit (rf of course) without the headrest. Should I take that on the plane since she is used to it? I am always nervous about the hassles from flight attendants about using car seats on the plane especially since I am always installing rearfacing and that seems to get more resistance. Should I take our Graco Safeseat for the flight? Am I less likely to get pressure to install it forward facing if I take it?
