I don't currently have any SWU's in my account... have plenty of LP milestones but waiting to cash them in. I am logged in and currently can't see the systemwide upgrade box by specific flights when I look at fares on AA.com. Did they remove the functionality to see SWU availability when you have none in your wallet (or was it always that way)?

I know they exist for these specific flights because I see them on EF.
