United Airlines and Chase have refreshed a small-business version of the airline’s co-branded credit card with a generous limited-time sign-up bonus.

Until March 18, the United℠ Explorer Business Card is offering the following Limited Time Offer: Earn 75,000 bonus miles after you spend $5,000 on purchases in the first 3 months your account is open.

With a round-trip domestic economy flight typically costing about 25,000 miles, the bonus alone could be good for three free flights. Or you could likely get at least one domestic flight in first class.

Chase notes the bonus offer is available to those who don’t have the card and have not received a new cardmember bonus for the card in the past 24 months.

The card has an annual fee of $0 for the first year, then $95.


The United℠ Explorer Business Card offers double miles on purchases from United, including tickets, seat upgrades, in-flight food, beverages and Wi-Fi, and other United charges. Other double-miles spending categories are:

  • Restaurants.
  • Gas stations.
  • Office supply stores.

Cardholders earn 1 mile per $1 spent on all other purchases.
