As far as I know, they have relaxed some of the liquid rules for carrying on the plane. But, this may change daily and according to airlines and whether a domestic flight or international. It is best to check before you go. I think the baggy is so they can see through it easily. I went to Vegas just after that all started so I made sure I put anything questionable in the checked bags. I didn't have a problem. But, if it was a short trip that I didn't need that much, I don't know. I can't imagine me going anywhere that I didn't have a lot of "stuff" with me and I don't like carrying anymore than I have to. It kills my back.
