Works to many other destinations ex-PRG - however not all the fares are so good (not always the cheapest option on the market at least).
The only one which I would call sexy is PRG - BKK for 36k czk / 1379 euro - you can do this cheaper with FlyDubai, but question is if their product can be really called "business" (or at least compared with OS and other old fashioned airlines). This is so far the cheapest regular business fare ex-prg to BKK I have seen in ages - typically the discounted AY is round 40k czk / 1532 euro.
