It's out of the question for carry-on luggage, but I'm trying to figure out a way to get Mountain Dew to the UK for my bf, who claims that he's never seen it in the UK, but also liked it a LOT when he tried it during his trip to the US. I found a webpage for ordering Mountain Dew from the UK, but the prices were outrageous, so what I'm trying to figure out is if there's a way to get a cheap 2-liter bottle of Mountain Dew here, take it with me, and not have it explode or leak or anything and mess up my clothes. Has anyone else shipped soda on a plane before?
