Take a look at the think tank 4 wheel spinner.
I just got one , to replace a tamron which I really like, but the spinner can be rolled along , no dragging on two wheels. Holds a lot and fits in the above head rack on a plane. You can remove some of the dividers for overnight stuff.
I have the airport security Think Tank. It is the only secure way to go. I keep my lenses, bodies and flashes in it secured to the frame in my cars trunk
