I don't believe so. Most liquids can't make it through security. You can check the airline's website. It should have the details.
Riiiiiiggghhht. That'll make it to your final destination.
OK, I checked Southwest's online policy and it says I can check up to 5 liters, as long as it is it's unopened packaging, securely packaged in corregated carboard designed to prevent leakage.
I'm getting tired of not having my scotch available when I travel, or having to buy a bottle of it at my destination. What I want to do is carry a bunch of those little airline travel size bottles, but I don't want to buy them from the airline, I want to buy them from Specs, where they are much cheaper. A flask is apparently out of the question. Something I'll have to work on.
