Given the changes for upgrades now with the new Regional and Global Upgrades, any word on what that means for Miles Upgrades both domestically and internationally? Even though DMs will no longer need M+ to use their GU Certs internationally, will mileage UGs still require K+ domestically and M+ internationally? I know this is a n00b question but don't miles and SWUs (and I assume starting in March RU Certs and GU Certs) pull from the same inventory?
