I'm *G (SAS EuroBonus Gold). I'm about to fly Y from Birmingham to Frankfurt on LH flight which is operated by Eurowings. Will I have a lounge access? I'm asking because it's not LH own flight and it seems to be a contract lounge. Are there any vouchers to be asked during check-in? Any other tricks or tips?

Any onboard if at all service differences between Eurowings and Lufthansa? How large is British Aerospace 146-300? Any particular good seats on that plane? It of course is not that important becase flight is less than 2 hours.
