While it's nice that some pilots want to speed things along and help with the bags, isn't that a big no-no? I thought I heard somewhere if you get hurt doing it you're ineligible for Workman's Comp. If so, be careful-you don't want to get punished for doing a good deed.
As an aside, I once had the displeasure of working with a FA (on a 2 FA a/c) who wanted to be helpful and thought getting off the plane and flinging bags was a great idea. I couldn't seem to get it into her thick head that there was soooo much wrong with that and she broke a FAR doing so. Her brilliant retort was that the baggage handlers really liked her.
