I bought this bag so I can fly with my bike. No issues so far, length will qualify it as over sized but until the weight limit is below required it should all be an easy flight with no extra charge. I only tried it with Qantas so far and only internally in Australia but so far so good. I fit helmet and bike tool with a pump in there easily. Only thing that you might want to add some rugs so the forks don't scratch up the paint on the frame. Very good quality, top stuff! Heavy duty and nicely rolls around with its big wheels.
