this be perfect for carry my 1 year old 's Marathon through the airport . we connect it to we roll carry-on suitcase . be very simple to use , relatively easy to disconnect and reconnect to suitcase at security check point . I have be plan to buy the Gogo Kidz cart instead for $ 70 , but be so glad I get this instead and save all that money . plus , it be much easier to store this little strap than the Gogo kidz cart .
