Citigroup to launch digital savings account for American Airlines cardholders

Citigroup said Monday it was planning to offer a high-interest online savings account early next year to users of its American Airlines co-branded credit card. The savings account, Citi Miles Ahead savings account, will offer up to 50,000 miles as a sign-on bonus and a 25% boost on miles earned through the card, the bank said. The digital service will only be available in areas where the bank does not have physical branches.<br/>
