Can i take a partially used container of toothpaste gel with me?

Question

I am flying on American Airlines from Bellingham, Washington to Las Vegas, Nevada.

Answer 1

you can always try anything you want.  How much does it cost if you lose it at the airport security?

Answer 2

You mean in your carry on?  

The container itself has to be 3 oz. or less.  The TSA has no way of judging how much gel is left in your tube.  

Answer 3

Yes you may if you put it in your checked luggage.  In Carry-on  luggage, you can only carry a 3 oz or smaller size.  See #1 under "What can I bring ?" on the site below.
