Citibank and American Airlines have introduced a cobranded card for small businesses.

The Citibank Platinum Select AAdvantage business card lets small- business owners earn rewards when they or their employees make purchases.

A business owner can open an account with up to nine additional cards for use by employees. One AAdvantage mile is earned for every dollar spent, up to 150,000 miles per calendar year.

The product is a counterpart to the Citibank AAdvantage card for consumers. The frequent-flier program was started in 1981 and has more than 35 million members.

"We've seen an increase in demand among business owners for card products that meet their purchasing and credit needs," said Faith Massingale, business manager for the Citibank AAdvantage business card.
