Description
Cents per mile (CPM) is a common indicator of good value for the frequent flier community when purchasing airline tickets. This extension will compute the CPM for the cheapest economy fares listed on American Airlines’ Price & Schedule matrix at aa.com.
Disclaimer: This extension has been developed by Kyle Duarte, and is in no way provided or supported by American Airlines.
Functionality
The extension will only run on the Price & Schedule matrix pages at aa.com, and will only compute CPMs for the Economy Super Saver fare column (the left-most one).
The extension assumes distances from GPS coordinates of airports (which may vary slightly from AA’s official flight distances), and adds $9.95 in taxes per segment, up to two segments for those customers purchasing in dollars. Obviously, this assumption is inaccurate for flights to/from AK, HI, PR, USVI, and abroad, but still provides a general guide to compare CPMs by itinerary.
