Benefits of the Delta SkyMiles® business cards

AmEx has three Delta business cards: Gold, Platinum and Reserve. Each offers perks for Delta flyers, including elevated rewards on Delta purchases, free checked bags (for up to eight traveling companions), early boarding privileges and discounts on in-flight purchases.

Here’s how the cards stack up:

Delta SkyMiles Gold Business American Express cardholders also get a $200 Delta flight credit for future travel after spending $10,000 in a calendar year on the card. Terms apply.

Should you get a Delta SkyMiles business card?

The Delta SkyMiles® business cards from American Express offer something for every level of Delta fan — from casual to die-hard. The key to squeezing value out of these cards: You must fly with Delta.

For most entrepreneurs, the Delta SkyMiles® Gold Business American Express Card will hit the sweet spot. You can net a cache of bonus miles (90000) and avoid an annual fee in your first year ($0 intro for the first year, then $150). Terms apply.

The annual fees are harder to justify for the Platinum and Reserve business cards unless you’re a Delta regular and will take advantage of other card perks. Otherwise, consider a general business travel card.

For instance, the Ink Business Preferred® Credit Card lets you earn miles no matter the airline. You’ll still get a stellar welcome offer: Earn 90,000 bonus points after you spend $8,000 on purchases in the first 3 months from account opening. But you’ll have more redemption options and a lower annual fee ($95).
