I don't know if this is the right place for it, mods feel free to move at will.

I'll be flying BLQ-PRG-SVO in Y in a few weeks and looking at the OK site they offer the chance to buy up to Business for 990 CZK, which is about 53 USD. Has anyone tried this before? Is it worth it? Is it 990 CZK per segment or for the whole trip?

Thanks
