I was looking at flights I might book HEL-CDG-NYC on DL.com, and one of the options that DL's website served up was an AF codeshare with Finnair HEL-CDG, connecting to DL metal CDG-EWR.

I am assuming that I'll get zip in terms of status given that Finnair is part of OneWorld, but since it's being sold on DL.com, I wasn't sure if there was some exception/loophole that I wasn't aware of. Anyone on the FT hivemind run into this type of thing before that can advise as to what to expect? It's not a super long flight HEL-CDG, so it's not a big deal if nothing carries over, but I'm more curious in terms of priority check-in/security, bag allowance, lounge access, etc.

Thanks in advance.
