I often fly MU and CZ within China, and most of the times they do not even recognize my Flying Blue FF card.

In small airports such as KRY or KCA the check-in clerk will look at my FF card, and iimmediately hand it back to me without a word (no point arguing, they don't speak english). No way to get priority boarding (there is no priority lane any way) and no priority tags for the luggage.

The most anoying is that I then have to mail the original boarding passes to AF in order to get credit for the flights
