I always pick "other countries/english".
- Noticed that *some* route source/destination combinations do not work and result in all sorts of weird errors.
- Also, occasionally, their so called "site security" seems to ban me either by ip or browser id, and then I just have to go use another device or come back in a few hours.

Given how poor availability is (most routes have nothing most days), sometimes hard to tell. But, for example, IST-CDG on March 29 works and has a few tickets available.
