Regarding wine in your checked baggage
Just returned from Buenos Aires with 15 botles of wine- 2 six packs boxed and 3 bottles in luggage wrapped in bubble wrap. The only potential problem we had was checking in at the Delta counter when asked about the wine we had boxed- when we said we had 12 bottles in the boxes, the agent started quoting the 5 liter rule- I protested that it only covered hight alcohol bottles- anyway it was resolved by assuring her that the bottles in the six packs were less than a liter. Two of us were travelling and the agent who took our bags told us that the 2 boxes of wine had to be checked under different names because of the 5 liter rule ( which really does not apply). At the US Customs end- we declared 15 bootles of wine and all we heard from the customs agent was "welcome home".

Thanks to Gaucho for all his advice and time!!!!!
