Delta Cuts MQM Earning for Some Aeromexico Business-Class Flights

Delta's slashing the number of Medallion Qualifying Miles (MQM) you'll earn on Aeromexico flights — one of its SkyTeam partners.

As of April 1, 2018, Delta is reducing the percentage of MQMs you'll earn on Aeromexico flights when traveling on some business-class tickets — on a C, D or I ticket. On the partner award chart for Aeromexico, Delta's current chart (prior to April 1, 2018) shows that you'll earn 200% MQMs for business-class tickets:

However, as of April 1, 2018, that same award chart changes. For flights occurring on or after that date, you'll earn just 150% MQMs for discounted business class — on a C, D or I ticket:

The good news is that nothing else is changing on April 1 other than those MQM earning rates. The number of miles you'll earn will remain the same (200%), and the number of Medallion Qualifying Dollars (MQDs) you'll earn will also remain the same (40% of the distance flown). Plus, if you're traveling on a full-fare business-class ticket (J), you'll still earn 200% MQMs.

Unfortunately, even if you had travel booked with Aeromexico prior to April 1, you're still subject to the new MQM earning rates. While it won't be a huge loss, it's still frustrating for passengers who purchased a business-class ticket with SkyTeam partner Aeromexico thinking they'd earn a full 200% MQMs.
