Not entirely true...
Was posted in the NW forum, that until a new agreement is reached with SkyClubs, only WC members will be granted access to the Midwest BCC in MKE. DL CR members do not gain the benefit, and anyone who eventually gets a new SC card once available, wouldn't get access until SCs has a YX agreement. Small point, but not for those of us here in MKE. It is expected that the agreement will continue with SC...not sure if this is true of any other previous WC lounge agreements.
Despite the SC/BCC situation, miles earning, redemption, etc with DL/YX is in effect.
