But as some found out using the short-lived AA flight to DME, the Russian visa documents are probably among the most onerous for Americans - iirc, they want to know every country you have visited, military service, etc. This all militates the OP make some speedy choices and decisions, particularly if headed to BRICs.

N.B. As this topic is really not about American Airlines, but is more related to oneworld airlines for RTW or similar travel, this thread will be relocated - no visa necessary. / Moderator
