Havking become a huge fan of weekend trips here in Norway and Europe (and to the US) I reached Scandinavian Airlines top tiper (Diamond, 100k miles or 100 segments) 5 months into my current earning period. As I then realized I will move to Grand Forks, North Dakota to start my Air Traffic Controller education and that Avinor (state owned company managing all Norwegian airports paying for my education) will buy the ticket to GFK with the routing OSL-AMS-MSP-GFK, which is one leg with KLM and two with Delta, both SkyTeam. Therefore I contacted China Airlines asking if they were willing to match my SK and *A status, which they were, giving me SkyTeam Elite+ for the next year as an Emerald Flyer.

Now I am very familiar with what I can get as *A gold, but I am curious to what I will get as SkyTeam Elite+, and some things seem quite unclear even after googling and searching around.

Example: Do I get an extra piece for free when checking in (the group ticket should already give 2x23kg) when the last leg is US domestic? How about lounge, as I understand it I will get access at AMS and MSP - how about the contract lounge KLM has at OSL? How is the upgrade policy among the other ST partners?

If anyone here, more familiar with ST than me, could maybe explain to me a bit more what the benefits usually are, that would really be appreciated.
