I track my AA free domestic upgrades on Yahoo notepad (53 of 54 cleared this year). As the AA website is pretty reliable with posting, haven't had the need to track actual flight miles (over 500,000 miles worth of flights have posted without a problem). Even with the little I track, I just found it too complicated to do it on an Excel spreadsheet on one specific computer. Google has an on-line spreadsheet application now that would be a good alternative to Yahoo notepad, as you can update as you're out traveling about. Have you tried it?
