For those who travel with video lights, be sure to disconnect the light heads from the battery before a flight. You might also want to tell the security people about the equipment and hang around while they scan it in case they have any questions. They said the lights were a hazardous, heat-generating item and needed to be completely disconnected.
That was advice I got yesterday after being called off the plane and running back to the check in area 20 minutes before the flight was scheduled to depart, so I could disconnect the lights since I didn't want them to do it for me.
Other than that, my camera usually sits inside of the housing and goes inside a Pelican case. Either checked in or carried on, depending on how much other stuff I have.
