I suggest that you leave your squirt bottles at home and stock up on mini liquor bottles instead. You'll avoid paying out of your ass for the airline's overpriced shots and you won't have to wait for the attendant to come back by for more alcohol. It's just a win win all around.
I just looked it up from our brave and fearless TSA agents that you can travel with as many mini liquor bottles that you can comfortably fit into one quart sized, clear plastic zip top bag.
Unless you're just partial to squirting booze into your mouth. You do you, bruh.
