DL Plat Business Card
I had an email with an application link sent to me by Delta in December to upgrade from the Delta Gold Business card to the Delta Plat Business card which had a phenomenal bonus attached. The link is still active and has the same terms on the app page. PM me if you want me to send it to you.
Here are the primary points:
For a limited time, with the Platinum Delta SkyMiles® Credit Card, you can get up to 50,000 bonus miles, including 15,000 MQMs.
1) Get 25,000 bonus miles (5,000 miles count as Medallion Qualification Miles MQMs) with your first purchase.
2) Get 25,000 additional bonus miles (10,000 of which count as MQMs) after you make $10,000 in purchases within your first 6 months of becoming a Cardmember.
3) Under Miles Boost, get 10,000 MQMs when you spend $25,000 each year and another 10,000 MQMs when you spend $50,000 in a calendar year.
4) One free domestic economy companion ticket each year upon renewal.
