I know that you who fly more than I do (which is all of you, LOL) are probably used to this, but how stupid is it that you can't bring a regular tube of toothpaste on a flight? Are they afraid of a Parent Trap (Hayley Mills version) attack?
What I find stupid about that rule is that even though a toothpaste tube may only have about 1/2 ounce worth of toothpaste in it, if the tube itself originally held more than 3 ounces, then the TSA is required to confiscate it. -I saw this happen a few times when I was traveling during Christmas. In any case...
As long as it's packed in your checked baggage, you'll be fine.
*And a friend of mine pointed out to me that a bunch of the high-end cosmetic lines have re-packaged and re-sized their "small sizes" in the 2.7 ounce range in order to prevent the "trauma" caused by someone having to throw out their $200+ tube of moisturizer.
