The Maxi-Cosi Pebble is one of the few infant car seats on the market that is approved by the TÜV for airline use. Unlike almost every other car seat, the Maxi-Cosi Pebble can be secured in an airline seat using a 2-point seat belt. However, as with installation in a car, the Maxi-Cosi Pebble must be placed in a rear-facing position, i.e. against the direction of travel.
