Hi, wondering if experts can shed some light on this. I will be flying on Austrian, just a short hop from CDG to VIE. - The segment from CDG to VIE is a code share, the actual operating airline is AF. - The segment from VIE to CDG is on Austrian. - Can I associate 1 FF account for the CDG to VIE segment, and another for the VIE to CDG? - If I have a Gold Medallion with Delta, does it provide anything on the code share flight? Seat selection, lounge access? Should I bother? - If I have Aeroplan Altitude 50K, is there any benefit listing that on the VIE to CDG segment? - How do these statuses work anyway, when there are flights ticketed by an airline that belong under an alliance, but operated by an airline from a different alliance?
