Delta wants to incentivize you to earn their currency with more of their partners. They get paid by those partners for their miles.

But they want to be careful not to be too generous and give you extra miles for the things you’d do already. So they have a new promotion that’s double miles through May 31 for partner activity you didn’t earn SkyMiles for in 2017. (Registration required.)

Eligible partners are:

• Hotels
  
• Airbnb
  
• Car Rental

• SkyMiles Cruises
  
• FTD
