this, though. If you are at least Ruby in AY's FFP and travel on an AY-marketed flight from HEL, then you get fast track. However, I think there was a recent post on the AY forum about someone having trouble getting fast track as an AY elite on an AY codeshare flight on BA metal, so it might not work in practice.
