I've done a rather fundamental spreadsheet where I list travel dates and destinations in column 1 and 2, and all my FF programs in 3 on. Under each FF program, I enter what I believe I should be credited for each trip..e.g. for HHonors, I have a column for points, one for miles, one for promo miles/points, etc.. some entries are merely X's, some are actual numbers.. when I actually am credited, I change font color in that cell. I put notes re: special promos etc for any particular trip in a notes field.

Kind of a pain, but I haven't had time to do anything slicker... It takes me about 2 hrs a week as much as I travel to do my audits at each FF site and update the spreadsheet. I'm not sure what it says about me that I actually do this, but I've "saved" many thousands of points this year.. miles are pretty accurate, so I'm probably wasting my time going thru the exercise - but I do it anyway! This year I'm adding trip cost in another column so I can tell how much money I'm giving the airlines and hotels!
