I used to drag a heavy car seat through every airport. Then one flight changed everything. FAA guidelines are clear: for kids under 2, lap-holding with the infant belt extension is allowed, but a CRS in their own seat is safest during turbulence. At 18 months, we switched to a lightweight FAA-approved seat — no more gate-check drama. The trick? Test it at home first so it feels familiar. Add a soft cushion like SlumbaPak Little Explorer for extra leg support and a privacy hood to block overstimulation. FAA also says: never use a booster or harness that isn’t approved. Simple, safe, and suddenly flying felt easier.
