Editor's note: Big changes are coming to Delta's SkyMiles program in 2024, including how members can earn elite status. The carrier will also be cutting back Sky Club lounge access. Read more on these upcoming changes here.

If you have the Delta SkyMiles® Reserve American Express Card or Delta SkyMiles® Reserve Business American Express Card, you already know that your card comes with a “Status Boost” to help you earn Medallion Qualifying Mile, or MQMs, — units you need to attain elite flyer status that comes with perks like complimentary upgrades, waived change fees and bonus Delta SkyMiles every time you fly. Spend $30,000 in a year on either card and you earn 15,000 MQMs, and you can do so up to four times a year for a total of 60,000 MQMs. Terms apply.
