The next six months should prove interesting to AeroMexico Club Premier members. The program has pledged to announce new program enhancements each month through December. June’s enhancements included the elimination of expiring frequent flyer miles as long as a member flies with AeroMexico at least once every two years and the ability to earn double mileage on all Clase Premier flights — up to 100 percent on international flights and up to 50 percent on flights within Mexico. Both of these changes are permanent.
