Grativis.com is a new mileage manager Web site you can check out in its beta stage. Currently, 27 airlines are supported, including the major U.S. airlines: Continental Airlines, United Airlnes, US Airways, Delta Air Lines, American Airlines, Alaska Airlines, Frontier Airlines, JetBlue and Southwest Airlines. Hotel programs include Hilton, Hyatt, Marriott, Starwood, Best Western, Holiday Inn and La Quinta. Other programs include Avis, Hertz, National and Amtrak.

Enter your account numbers and passwords and Grativis.com will track your account balances, including charting your progress toward award flights. Click your account name to see more information, including your elite status and lifetime miles. You can view a short instructional video that will guide you through the process of adding your accounts. When we tried to enter our accounts and begin tracking our miles and points, however, we were unable to save our account names and passwords. We contacted customer support and received a response within hours and the problem was fixed by the next day. Grativis.com is in beta stage and as such, they are still working out the bugs. Enter the referral code INSIDE-FLYER to check it out.

Bottom line: Compared to other online managers, Gravitis.com doesn’t have any special features that set it apart from the other Web sites already out there, such as http://www.mileagemanager.com and http://www.awardwallet.com
