Hi:

Soda is extra and I bring mine with me. I usually get the 20 oz six
packs and pack three to a jumbo zip-lock bag (give the tops and extra
"screw" as you pack them) and scatter them around the suitcase(s) with a
little stronger stuff in a similar bottle mixed in (lol). However, we
have just carried on a case (when we had our boys with us) on HAL when
it was docked close to a store that sold them. HAL didn't seem to care
about that or the beer we had.
