If you use Chrome or Firefox for your Internet browser, you might want to check out the AA CPM Extension (plugin) that was created by a FlyerTalk.com member, Kyle Duarte. The tool will calculate the CPM (cents per mile) for American Airlines flights that are being displayed on the Price & Schedule matrix pages at aa.com. The CPM is computed based on the cheapest economy fare column. The extension uses GPS coordinates to add up the miles earned and adds $9.95 in taxes per segment, up to two segments. The online tool can be downloaded at http://insideflyerus.wpengine.com/link/?3805

Bottom line: The tool will help frequent flyers, especially mileage runners, know at a glance if a fare is offering a good cents per mile ratio. Duarte mentions that, “This extension is written entirely by me on volunteer time. It is in no way written, distributed, endorsed, supported or in any other way related to American Airlines other than using pricing data AA provides publicly on its website. The extension demands none (zero, zip, nada) of AA’s web server resources to calculate CPMs.”
