American Express Co ranked highest in consumer satisfaction among U.S. credit card issuers for the second straight year, according to a J.D. Power and Associates poll released on Wednesday, which cited its benefit and reward programs.

American Express, the fourth-largest U.S. credit card issuer, was followed in the rankings by Discover Financial Services.

Both American Express and Discover improved their performance from last year's survey and were the only two companies whose scores topped the industry average in the poll.

JPMorgan Chase & Co, Citigroup Inc and Bank of America Corp appeared in the fourth, seventh and ninth positions in the rankings, respectively, according to J.D. Power, a unit of McGraw-Hill Cos.

The poll, conducted in April and May, received responses from 7,665 credit card users.
