Totally solved our difficulty travelling.  We make long trips yearly with two kids 3 and 6.  This year we repeated a trip from last year.  Anchorage, Alaska to Cancun.  Last year was a terribly stressful trip.  This year was super simple, just one little handy device made a huge difference.
We always do a flight that has a 39 minute layover in Phoenix.  This is a problem with a real stroller because you have to wait for them to bring it to you from under the plane.  The wait for your gate checked stroller effectively burns every second of extra time you might have.
We like many also received many (hundreds) of comments from strangers loving the Ride on Carry on.  This totally reinforced my sons love of his seat and he wanted to be in it every second because it was "awesome" if you're in doubt I'd definitely buy this.  Well worth the money and very simple to travel with.
