“Bask Bank
According to its website, Bask Bank launched the first online-only savings bank in the U.S. in 1999 as Texas Capital Bank. It is an FDIC-insured institution and has partnered with American Airlines to help customers earn miles. To that end it offers the Mileage Savings Account. Customers earn one American AAdvantage mile for every $1 saved annually in the account.
“If you prefer to interest, Bask’s savings account currently pays 0.80% APY.”
