A friend and I are traveling to France in August and trying to book our train tickets in advance. We are both under 26 and would like to buy a Carte Jeune to save money, as we'll be traveling by train most of the time. However, when we try to buy these on the SNCF website, we're asked to select our country of residence -- and the U.S. isn't an option.
Some other countries, like Australia, are left off as well.
I can't find anywhere on the website's rail card pages that says that these cards are limited to people from specific countries, but I was wondering whether anyone could confirm that U.S. citizens are able to buy them? If there's no restriction, we can buy the Carte Jeune-priced tickets now, I believe, and just pick up the rail card itself when we arrive, but I don't want to buy the tickets and find out we can't buy the rail card when we get there!
Thanks, any help would be appreciated!
