Delta SkyMiles members can now link their accounts to Uber, earning miles for money spent on rides and food delivery, the companies announced today. The news kicks off a partnership between Uber and Delta Air Lines that was first announced earlier this year.

Once a customer’s accounts are linked, they can earn one mile per dollar spent on UberX rides to the airport, two miles for every dollar spent on premium rides like Uber Comfort and Uber Black, and three miles per dollar on Uber Reserve trips. For Uber Eats, customers can earn one mile for every dollar spent on orders over $40 from restaurants and grocery stores.

Likewise, Delta customers can now use the airline’s smartphone app to book an Uber ride to or from the airport. And later this year, SkyMiles members who log in to the in-flight WiFi will receive a special offer of 30 percent off to book an Uber Reserve ride for pickup when they land.

Uber is the latest to team up with Delta for expanded loyalty earnings. The airline has also formed partnerships with Starbucks, Hertz, and Ticketmaster.

Delta had previously teamed up with Lyft on a similar deal to earn miles from ridehail trips. Now, the airline has dropped the smaller rival in favor of Uber, which is significantly larger in terms of market share, ride volume, and revenue.

Introductory pricing will be $10, which rises to $18.50 after the promotion. Starting in May, Uber will offer multiple routes from Downtown and Midtown locations to and from the airport, with service every 30 minutes from 6:00am – 10:00pm, 7 days a week. The company says it said it’s currently in talks with Boston’s Logan International Airport about bringing its shuttle service there.
