Delta takes a 'mortgage' out on frequent flier SkyMiles for $6.5B

Delta's frequent flier program has more than 100 million members and generated $6.1 billion in cash in 2019 from sales of miles to its SkyMiles credit card partner American Express, SkyTeam airlines and other partners. The partners offer Delta miles to their customers as incentives for purchases and other transactions.
