Hi all, I hope somebody can advise on the following situation as to what my options are.

I made a few bookings recently through online travel agents on airberlin stock. The prices were really cheap as the trips started at BTS with flights from NIKI, but some of the bookings contained BA coded flights, for example:

BTS-VIE-LON-ACE//ACE-LON-VIE-BTS - HG, BA, BA, BA, BA, BA, HG - 10,976 Avios, 160 TPs (168.72 EUR)
BTS-VIE-LHR-LCA//LCA-LHR-VIE-BTS - HG, BA, BA, BA, BA, BA, HG - 11,208 Avios, 60 TPs (240.79 EUR)

NIKI has literally just announced that they (more likely their boss, airberlin) have pulled the plug on a BTS service before it even started.

I always thought that it was possible that they would cancel the service but I don't know what my options are if I want to keep the BA flights (which I'd like because of Avios/TP's). Would the agent allow me to just drop the HG flights, but keep the BA sectors? Do I have any rights?

Thanks in advance for any answers.
