Does the Britax Advocate ClickTight rear-face longer than other convertible seats?

20 of the 50 convertible seats we track rear-face to a higher weight than its 40 lb. The highest is the Axkid One 3 at 65 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 Britax Advocate ClickTight on a plane?

Yes, Britax 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.

Is it OK to buy a used Advocate ClickTight?

NHTSA publishes guidance on used car seats on its car seat page. Britax lists a lifespan of 10 years from manufacture for this model. Check the label and the maker's instructions, and ask your pediatrician about your child.
