It seems to me that your looking into a BP/W only for your travel purposes and not because of its benefits over a jacket bc.
Try diving a BP/W if you havent already, and if you like it, it will be worth the extra lbs (depending on your setup). If not, stay with your current bc.
I own a Dive Rite SS BP with an Oxycheq Signature 30lbs. The way i do it is backpate goes into a backpack (carryon luggage) and the wing goes into my other bag. I also have a mesh scubapro bag thats intended for fins, mask and snorkel, but i manage to fit my reg, bp and wing into the same bag with all the other items. The point is, you can fit all your scuba gear in one bag weighing under 16lbs.
