The Britax Car Seat Travel Cart is a convenient alternative when traveling through airports with your car seat and child in tow. Car seats attach effortlessly using the car seat LATCH connectors, the same connectors that secure your car seat tightly to your vehicle. Its compact fold allows it to fit into small spaces for storage, including most airplane overhead compartments. With its durable steel frame design and easy-glide wheels, the Britax Car Seat Travel Cart can be used with children harnessed in car seats for short travel distances. The raised platform protects the car seat from contacting the ground, while the one-hand telescoping handle adjusts to fit any height caregiver. This baby car seat cart accommodates all Britax Convertibles and Harnessed Booster seats. We are not permitted to install car seats.
