I'm considering applying for a Delta SkyMiles credit card. The Platinum card says you can get 5,000 MQMs (Medallion Qualification Miles) and up to 30,000 bonus miles. Based on the wording I think there a difference between MQMs and 'bonus miles'. Google has not helped me. 5,000 miles towards raising my status is not a big deal (looking at the card fee) but 30,000 miles towards my status is a big deal (understanding I would have to make purchases). But 30,000 miles that don't raise my status would just make me angry.
Is there a difference, on the SkyMiles Platinum card, between MQMs and 'bonus miles'?
