Forgive me if this info is elsewhere, I did some digging and didn't see it. I have a trip in a couple months with connections in DEN then ORD. I know in ORD I can use the RCC Lounge as it is my layover before the ORD-FRA segment. What about in DEN? The layover is quite long (4 hours) and I would love to be in the lounge. I think I am allowed as I have a international flight in the same day, but I have seen mixed information.
