Just the Tip:

Get the Delta SkyMiles Platinum Business Amex if you fly Delta for work and can plan one trip a year with a companion. Each year after you renew, its companion certificate puts that person on an economy round trip for only the taxes and fees. That certificate is what justifies the $350 annual fee.

It’s the business version of Delta’s $350 Platinum card, and since sole proprietors need no federal tax ID, a side business is enough to apply. It swaps the personal card’s dining and supermarket bonus for one on transit, U.S. shipping, and large purchases, and raises the Delta Stays hotel credit from $150 to $200.

Key Features

  • $350 annual fee, no foreign transaction fee, and a 19.74% to 28.74% variable APR (interest rate)
  • 100,000 bonus miles after $8,000 in purchases within your first six months, worth about $1,000 off Delta flights at $50 per 5,000 miles (offer ends Nov. 4, 2026)
  • 3X miles on Delta and hotels paid directly; 1.5X on transit, U.S. shipping, and single $5,000-plus purchases, up to $100,000 a year combined; 1X otherwise
  • A companion certificate after each renewal for a Delta Main (economy) round trip in the U.S. or to Mexico, Central America, or the Caribbean
  • Free first checked bag for you and up to eight companions on one reservation, your second bag free on domestic flights, and priority boarding

Pros

  • A companion flies the certificate trip for $22 to $250 in taxes and fees
  • $2,500 credited each year toward the $5,000 in qualifying spending Delta requires for Silver elite status
  • Up to $200 a year for prepaid Delta Stays hotels, plus $10 a month each for U.S. Resy restaurants and rideshares
  • No-fee employee cards whose purchases earn you miles

Cons

  • No companion certificate until you renew and pay a second $350 fee
  • Most certificate-eligible fares need up to 14 days’ advance purchase and a three-night minimum stay
  • No Delta Sky Club lounge access
  • Employees flying without you get no free bags or priority boarding
  • 1 mile per dollar on most purchases, worth about 1 cent each

It suits owners who fly Delta for work, since from the first renewal on, one certificate used on a fare above $350 before taxes covers the fee. If free bags are all you want, the Gold Business has them for $150 a year after a $0 first year, and the $650 Reserve Business adds Sky Club visits.
