Seems as though what's allowed changes depending on what airport you are inspected in. A surprise??? A week ago I flew COS-MCI, and had one baggie holding small toiletries, and another with three mini-bottles of rum. TSA at COS said both baggies had to be taken out of the carry-on, but did not challenge my having two quart baggies.
Returning from MCI was told in no uncertain terms that only one baggie was allowed, and thus rum and toiletries would have to go in together. That made for a pretty full baggie.
Was also told at COS that "up to 4 oz" containers were allowed, but at MCI was told, no, only "3 oz".
