Is there any fare tracking system that's good for tracking flights that you've purchased so you can easily take advantage of fare drops? It's fine to do manually if you only have a couple flights, but I'm starting to get a lot of reserved flights for ski season and doing it by hand is painful.

Back in the day Yapta used to do the job, but they're long gone.

TripitPro claims to do it, but my experience is that they loose fare information on the majority of imported flights, and they think there's a $125 Alaska change fee (you can manually adjust by just changing the price of your fare, but you don't always get manual fare controls).

Kayak/Google flights are only useful for tracking Saver fares, and that's pretty useless (unless there's some way on those to exclude Saver fares?). Kayak does have a "no change fees" checkbox, but that's not what it actually does; it just gives you fully refundable flights.
