Milewise tracks more than 200 rewards programs and calculates the cash value of points or miles. (For instance, this writer has a little over 14,000 miles from one airline, which Milewise estimated to be worth $211 in rewards.) Like many of the other mileage tracking programs, Milewise compares real-time fare availability for the major airlines based on miles, points, or cash. It also advises the user on which options make the most sense, given the price and the user's point balance. It's also one of the newer options, since it launched in August 2011.
Founded in 2010, this free site tracks hotel and airline rewards programs, as well as daily deal sites like Groupon and car rental programs. Users can check bonus offers to earn more miles, and its search engine capabilities show mileage redemption options. Joel Coffey, an accountant in Seattle, uses GoMiles' expiration date tracking to "see which miles are close to expiring without having to log in to each of the individual airline websites." (He's lost miles in the past due to account inactivity.) Although he and his wife don't log thousands of miles each year, Coffey says it's still useful for casual flyers to participate in mileage programs and track their miles using a single website like GoMiles.
