I use the new Pelican that will fit in the overhead. I put my video
camera inside the housing. I also put my digital camera inside it's
housing. I make sure both housing are well protected using form
and bubble wrap. I use a TSA lock to secure the Pelican case when
I'm on a plane to small to use the overhead and the carry on's need
to go in the cargo hold. I realize this will not work if you have something
large, say a FX-1. However, for my A1U and C-5060 camera, I can fit
both camera and housing into the Pelican for carry on.
