American Express card members can get special referral bonuses when you refer your friends to apply for a new American Express card account.
If you are an American Express card member, you can earn a bonus reward when your friends and family get an American Express card via your referral.
Plus, your friends will also receive a bonus reward when signing up for a new American Express card via your referral, so both you and your friends will benefit.
However, the new card member bonus is usually the same as the standard offer from American Express, so there is not a higher bonus available for new card members exclusively through the referral program.
