AT&T is taking to the skies via a new partnership with Delta Air Lines and it’s taking Nokia’s Lumia devices along for the ride. 

According to a press release, Delta Air Lines has signed a multi-year agreement with AT&T for custom mobility services, devices and support for Delta’s new, in-flight, mobile point-of-sale (POS) application. 

Under the terms of the agreement, AT&T will equip more than 19,000 Delta flight attendants with Nokia Lumia devices powered by Microsoft Dynamics mobile POS platform on Windows Phone 8, with a Delta-specific customer experience developed by Avanade to operate over Wi-Fi and AT&T’s 4G LTE Network. 

Avanade will provide Delta with ongoing support, maintenance, and application enhancements for the next three years. The phones will allow Delta flight attendants to sell food and other goods to passengers, as well as seat upgrades. 

AT&T will be equipping the flight attendants with Nokia Lumia 820 devices, but the company says the agreement will see Delta Air Lines crew expanding to the newest Nokia devices over the next three years.
