Which size liquids can i bring on my carry-on?

Question

The TSA website says 3 oz but the US airways website says 3.4 oz.

Answer 1

It's 3 oz. or less, but since you have to put them in a zip lock bag, I don't think they're going to check to make sure it's exactly 3 oz. If it's something a lot bigger, like 6 oz, then  they will notice and pull it.

Answer 2

I recently traveled ..and was told 3oz or less.
