Delta recently announced a new partnership with Lyft, letting you earn Delta SkyMiles for every ride you take with Lyft. You can get 1 SkyMile for every $1 spent with Lyft on all rides, and 3 SkyMiles per $1 on rides to or from an airport, even if you're not flying Delta. It gets better, though: there's a way to get 1,000 extra Delta SkyMiles through this new partnership by taking just a single ride. . .
