Hi Nightrider ,
1. About the upgrades in Jet4you , I didn`t know.May be this is also valid for AA.
2. AA does not assist you in anything.You are left at your own even if you don`t speak french which is the case of most of us.
3.Yes , you can open a convertible account and bla ,bla,bla. But the currency at the bank is very expensive and the cost of an international transfer is expensive too.
What I do is to change in the black market and take it with me to Europe in the pocket.You will save much money.
