Make the Most of Your Miles: Webflyer.com

Click Factor: From the skinny on which airlines are most likely to give you elite-status upgrades and the amount of miles you’ll get for a particular flight to the conversion rate for transferring miles between programs, WebFlyer will help you earn and redeem your miles wisely. The network also offers mileagemanager.com, a $15-per-year online service that tracks your various memberships and alerts you when miles are about to expire.

Drawback: Because of a dated design, browsing is a bit of a multiple-windows chore.

Runners-up: frequentflier.com, traxo.com, mileblaster.com.
