So, um, using the logic that ice would not be allowed: what about liquid nitrogen/oxygen then? Surely they must be okay since they'll turn to vapor once warmed to ambient temperature?
Maybe if I ever show up for a flight really early I should come prepared with some ice in one container, and some liquid nitrogen and argue that at least one of the two should be let through...

The knowing scientists keep those in a Dewar flask and no pressure is required. Almost all liquid gases are contained in this way

AA, for example, permits 4.4 pounds of dry ice for carryon and 5.0 pounds in checked bags.
