American Airlines Business ExtrAA Program

Clark University is enrolled in the American Airlines Business ExtrAA program. This program enables Clark to earn Business ExtrAA points every time an employee travels for business on American Airlines, American Eagle or AmericanConnection carriers. The University can then redeem these points for free air travel. At the same time, you will continue to earn your individual AAdvantage miles as usual.
