I've added Fastfil1's template to my Flyertalk Mileage Spreadsheet page. It includes some good ideas and better underlying programming than mine.

Anyone else care to share, or to rewrite either of these spreadsheets? I'd like to see this develop into some good choices before we all start logging our 2007 flights.

btw, if you e-mail your spreadsheet for posting, make sure it doesn't have personally identifiable data, and in particular look under file/properties/summary, delete your name and company name (unless you want everyone to be able to see that).
