Delta Air Lines and American Express are running limited-time welcome offers on their co-branded credit cards. These promotions, available through April 1, 2026, provide a significant opportunity to earn SkyMiles, but understanding the terms and restrictions is crucial.

The Current Offers: A Tiered Breakdown

The welcome bonuses vary by card tier. Here’s a summary:

  • Delta Gold Personal Amex: Earn 70,000 bonus miles after spending $3,000, plus an additional 20,000 after $2,000 more within 6 months.
  • Delta Gold Business Amex: Earn 90,000 bonus miles after spending $6,000 within 6 months.
  • Delta Platinum Personal Amex: Earn 80,000 bonus miles after spending $4,000, plus an additional 20,000 after $2,000 more within 6 months.
  • Delta Platinum Business Amex: Earn 100,000 bonus miles after spending $8,000 within 6 months.
  • Delta Reserve Personal Amex: Earn 100,000 bonus miles after spending $6,000, plus an additional 25,000 after $3,000 more within 6 months.
  • Delta Reserve Business Amex: Earn 125,000 bonus miles after spending $15,000 within 6 months.

All cards offer introductory annual fees of $0 for the first year, except the Platinum and Reserve cards, which have fees of $350 and $650, respectively.

Card Perks: From Free Bags to Status Boosts

The benefits scale with the card tier. All Delta Amex cards offer perks like free checked bags, priority boarding, and discounts on in-flight purchases. Higher-tier cards (Platinum and Reserve) include annual companion certificates, potential status qualification through spending, credits for Global Entry/TSA PreCheck, and enhanced Delta Sky Club access.

Amex Application Rules: Stacking Bonuses Strategically

American Express has restrictions on multiple applications. You can only earn the welcome bonus on each card once. More importantly, Amex limits eligibility based on previous card ownership:

  • You are not eligible for the Reserve bonus if you’ve previously held that card.
  • Platinum requires that you have not held the Reserve, or even Platinum itself.
  • Gold requires that you haven’t held the Reserve or Platinum.

This means applying from the least premium to the most premium card is often the best strategy to maximize bonus opportunities.

SkyMiles Value: A Practical Currency

SkyMiles aren’t known for luxury redemptions, but they have a solid floor value of at least one cent per mile towards Delta purchases. Features like “Pay With Miles” and the 15% award discount for cardholders make them useful for domestic and short-haul flights.

The Bottom Line: The current offers on Delta Amex cards are lucrative, especially for frequent Delta flyers. If you can meet the spending requirements, now is an ideal time to apply. Just be mindful of Amex’s application rules to maximize your earning potential.
