I’m with all of those that take everything but tanks/weights.
The one time I didn’t (because of weight restrictions on a small plane from Cairns to Cooktown Australia) I didn’t bring my BC. Of course, the dive op didn’t have a rental bc for me either in Cooktown, so they ended up bringing a BC for me on the plane anyway.
The rental BC was too small and old, not the new scubapro that was promised. I didn’t end up having any problems, but I learned that I will bring my own going forward.
