Delta Cargo is partnering with crowdsourced delivery service provider Roadie to offer door-to-door parcel delivery nationwide, the companies said Tuesday. 

The deal makes Delta the first U.S passenger airline to offer such a service, the companies also said. The Dash Door-to-Door program is now available from Atlanta to more than 55 cities nationwide, with plans to add "dozens more" cities before the end of the year, according to the companies.

Dash Door-to-Door pairs TSA-approved drivers with air cargo to create cross-country same-day delivery service. The companies say the program was created for time-critical shipments in industries such as medical, manufacturing, automotive, industrial parts, and more. Using the program, customers can book on Delta Cargo and get a quote for flights with pickup/delivery as well as end-to-end tracking and real-time status updates. 

Roadie says the program builds on its already extensive same-day delivery footprint, which includes a network of 150,000 drivers nationwide and reaches 89% of U.S. households. Expanding the program coast-to-coast is the next step in the firm's growth, company leaders said.

"Customers want what they want when they want it," Marc Gorlin, Roadie founder & CEO, said in a statement. "This partnership means we can deliver—whether it's across town or across the country. Roadie was first to market with an 'on-the-way' delivery service utilizing excess capacity in passenger vehicles already on the road. Expanding our model into the belly of a 737 is just the latest step in realizing our vision to make same-day delivery faster, more efficient, and more sustainable."

Dash Door-to-Door is for packages less than 100 pounds and less than 90 linear inches and is available to all customers, the companies said. TSA Known Shipper status is required to ship packages over 16 ounces. The service is available 24/7 and has a limited money back service guarantee, the companies also said.
