I will be traveling on Emirates from JFK to DUX on A380 later this month. As CO Platinum/SkyTeam Elite Plus, do I have any additional access to Emirates services such as priority checkin, lounge access, etc? Already gave them my onepass to earn miles.

Can I access SkyTeam lounges in JFK or DUX if I am traveling on Emirates?

Anything else a first time Emirates traveler should know?

Thanks for your help.
