I'm usually pretty close to the limit on baggage weight, so I never use a regulator bag. Sometimes if space is tight I'll take the stages off the hoses, coil up the hoses, and put the 2nd stages in socks, then wrap them up in a wetsuit. The only piece of dive gear I ever carry on is my computer. I've never had a problem. Regs are pretty tough.
