CARD OVERVIEW

The American Express Platinum Delta SkyMiles® Business Credit Card is known for helping frequent Delta travelers rack up miles quickly, thanks to boosted earnings on Delta purchases and travel perks like priority boarding and a free checked bag. It also typically comes with a solid welcome bonus and an annual companion certificate, though it carries a mid-to-high annual fee.

Most users say the card delivers good value if you fly Delta often. Many reviewers mentioned how the free checked bag and companion ticket easily offset the annual fee, and business owners like the ability to earn extra miles on large travel and shipping expenses.

On the flip side, cardholders often complain that the perks feel “Delta-dependent.” If you don’t fly Delta regularly, the benefits shrink fast. Some users also wish the everyday spending rewards were stronger and note that the APR can be on the high side.

Personally, I think this card makes the most sense for business travelers who are loyal to Delta and want predictable perks every year. If you’re chasing flexible rewards or want premium travel features without committing to one airline, there are better options out there.
