Delta Air Lines is renewing its lucrative contract with American Express, striking a deal that extends through 2029.
Airlines generate millions of dollars in revenue by selling miles to credit card issuers.
Delta added 1 million new American Express card members annually for the past two years. The company said earlier this year that its relationship with American Express contributed $3.4 billion to Delta in 2018.
Delta said Tuesday that it expects its benefit from the relationship with American Express to double to nearly $7 billion annually by 2023.
The last Delta-AmEx deal was set to expire in 2022, but the two companies are renewing the agreement early. Delta is American Express’s largest co-brand partner and its only such consumer U.S. airline partner.
