US Airways MC - difference between Premiere WMC and WMC

[lg8302ch]

hi everyone

I just asked Barclays what the difference is between the Premiere WMC and the lesser WMC version I got approved for. (US Airways MC)  All CSR and analyst are pretty clueless and told me it has a lower AF but the rest pretty much the same.  As for the missing perks and benefits nobody seems to really know. So I figured I will ask the knowledgeable community here. Did anybody get approved for the lesser WMC version and was able to figure out the difference?

Basically, no difference for regular folks.

Thanks. So the US Airways Premiere WMC is in fact a WEMC?  Mine apparently has 10$ lower AF and is WMC but this card does not even show on the Barclays site😜 so I do think there are some perks missing for the lower AF.  Also it is unclear if eligible for the sign up bonus of 50K miles ...this will hurt me most.
