airberlin topbonus - Niki - BA Gold benefits in Vie

Hi Guys
flying soon out of Vienna for the first time with Niki, will my BA gold card give me any benefits (Priority check in, Lounge etc)?
Thanks

My experience is only on AB flights as a QF-Plat (Emerald).

You get Lounge Access, Business-Class Checkin.

For your free seat reservation you have to call AB - you even get the XL-Seats for free.

My boarding Passes got a "Fast Track" Sticker as well. So you may use the Fast Track Security.
