It's there, just hidden. If you log into your on-line account on NWA.com, on the first screen that gives the balance summary, click on "account summary" in the top menu bar. On the next screen in the paragraph at the top of the page, look for "To view your WorldPerks used mileage (debits) account history, click here." Click on the link and it should bring up all the debits out of your account, including mileage upgrades. Hope this helps....
