I am due to fly from Frankfurt to Vienna with Niki (Air Berlin) tomorrow morning.

I'm a Oneworld Sapphire and have managed to reserve some emergency exit seats for me and my partner on the Embraer.

I have just checked in and have seen that my seats have changed to 1D and 1F.

Have I been bumped to Business Class or do Niki not operate a Business Class on shorthaul?
