OW Status with S7
 

I have just checked in to a flight from VIE>DME>ASB on S7, I'm BAEC Gold/Emerald.

When I first got my boarding passes I was listed as Platinum (Emerald) for the first leg, and Gold (Sapphire) for the second leg. I just received an update to the first leg which is now also gold. Shouldn't both be Platinum/Emerald. Has anyone had this issue before?

Out of hundreds of flights with them, I never had that issue and I am always listed as PLAT/EMER (the system will always list all Emeralds as Platinum, even if you are a BA Gold or an AA Exec Platinum.

It would be interesting to see what status will appear on the paper BP, although there is not much difference between Emerald and Sapphire on S7, apart from the higher op up chance (which would not be the case here anyways because both flights are operated by A319s with Full Y configuration).

Were you BAEC Gold/OW Emerald when the flights were booked?

Yes I was gold when the flight was booked too.
