During the 2014 Medallion Qualification Miles promotion, MQMs were available for purchase in increments of 2,500 miles and up to a maximum of 10,000 miles. Costs per mile depended on Medallion status, and general SkyMiles members paid $625 for 2,500 miles, Silver members paid $725, Gold members paid $925, and Platinum and Diamond members paid $1,025. Earn MQMs year-round by flying Delta Airlines or by using a Delta Airlines Platinum or Reserve credit card.
