My favorite camera bag for domestic and international travel is the Think Tank Airport Roller Derby V2.0. I pair that with the Think Tank Vision 15 which holds two laptops, accessories and additional camera gear if needed!
I love having four wheels for easy and accurate control while moving rapidly through an airport, navigating escalators, standing in line, etc. The Vision 15 slides easily over the handle on the roller derby forming the perfect duo for easy transporting of gear without having the weight on your back.
