Can I take the MiniB on the Airlines?
Yes, but the tank must be empty. The Mini-B has been transported domestically and internationally both with and without the valve in place. The size is about 24″ x 24″ x 9″ and will fit into a standard overhead bin. It has been transported both as carry-on and as checked baggage. In baggage, you should take the valve out and place it into one of the internal weight pockets just to make things easier on the TSA folks as they will certainly open the bag to inspect the tank. And, it should definitely be put it into a bag to keep it clean. For carry-on, you can simply open the valve to let the security people know it is empty.
