The Platinum Delta SkyMiles Business Credit Card provides 2X miles per dollar for purchases directly from Delta. You can also earn quite a few bonus miles through the signup offer. That includes 5,000 Medallion Qualification Miles to help you gain a higher status level more quickly.
There’s a $195 annual fee for this card. But you’ll get valuable airline benefits like priority boarding, a free companion pass every year, and a 20% discount for in-flight purchases. And it also comes with Amex OPEN business benefits. That includes free employee cards, business-trained customer support reps, and account management features.
