I really want to pack just carry on bags for our trip to cancun in March. I have read the TSA web site and still have a few questions. If I can carry on a bag and a purse, can I have a clear quart sized bag in each? Will they not allow lip gloss in a purse without it being a quart sized bag? Also, what about regular solid deodorant? Is that suppose to be a zip locked bag too? Thanks.
