Checking it in
Most airlines carry a car seat for a child, at check-in or at the gate, often at no charge. The rules differ, so check with your airline before you fly.
Using it on board
A car seat can be used on board only if the airline allows it and the seat is approved for use in aircraft. Booster seats are generally not allowed during take-off and landing.
Or travel light
Rent a seat at Prague arrivals instead: we hand it over when you land and collect it before you fly home.
