15 of the 70 all-in-one seats we track rear-face to a higher weight than its 40 lb. The highest is the Britax One4Life ClickTight All-in-One at 50 lb. NHTSA: stay rear-facing "until he or she reaches the top height or weight limit allowed by your car seat's manufacturer." (NHTSA)

Can you bring the Graco True3Fit LX 3-in-1 on a plane?

Yes, Graco lists it as certified for aircraft; look for the red-lettered label that says so. The FAA asks that a car seat go in a window seat so it doesn't block the aisle, and the crew will look for that label.
