I'm hoping this is the right thread for this question - I've got a fairly tight MUC - IAH - DEN - CPR itin coming up. I'll hit Plat in the middle of the MUC - IAH segment. There is R space available at the moment - if there are IRROPS, will being a Biz class customer on an R ticket do me any good at all, or will my status (gold or plat depending on when the new status clears) be as good as it will get for me? (This is only an "is it worth it to upgrade" question insofar as IRROPS.... otherwise I'll be okay in E+)
