I am bringing my tuba to college and need some travel advice. My parents won't buy an extra seat so it has to be checked, and I only have a hard case.

The last time I flew internationally with a tuba, it arrived with the case completely wide open. I know TSA has to open it for a manual inspection, but they failed to close the buckles properly afterward and also removed the velcro strap I put around it.

Does anyone have a solution for this?
