airberlin topbonus - Does AB ever release more than 2 seats on DUS-CUR?

Hi,

I need to fly to CUR and have a bunch of Avios points. I would like to go for 1 week on business class and the dates are quite flexible.

Searching via BA it seems they only release upto 2 seats on each flight for points redemptions, do they ever release more than that?

Thanks
