Delta's mileage program.
Every flight you check in for earns SkyMiles - the longer the flight, the more you earn. Miles also count towards your tier.
Use your miles to upgrade your cabin. You only pay the difference between your current cabin and the new one, and spending miles never lowers your tier.
The more you fly, the more every flight is worth.
