Road warriors who own a small business now have a new way to rack up reward miles with United Airlines.

United's MileagePlus Small Business Network, introduced Friday, is the first U.S. travel loyalty program that rewards companies for nonairline purchases.

The program is separate from the carrier's PerksPlus, which rewards small and midsize businesses when their employee travel on United, United Express or Lufthansa.

Miles in the Small Business Network are earned with purchases of goods or services from more than a dozen vendors, including Apple, Home Depot, UPS and Staples.

Earned miles can be put toward air travel, entertainment and merchandise, or can be transferred to an individual traveler. United also lets miles earned in this program be bid on in auctions for unique experiences.

"Our new Small Business Network offers great value to businesses of all sizes, from those just starting out to those that are well-established."
