Delta Air Lines has put its first wi-fi-equipped international aircraft—a Boeing 747-400—into service, the carrier says.

The aircraft also marks the debut of Gogo’s Ku-band satellite-based connectivity service. Delta is installing the service on its entire international fleet. The carrier has Gogo’s ground-based service on its 570-aircraft mainline domestic fleet.

Delta’s 747 fleet is the first to get the service. Three have been modified, and the other 13 will be done by mid-year.

Gogo is scheduled to complete installation on Delta’s entire 150-aircraft international fleet, including its Boeing 777, 767, 747, Airbus 330 and transoceanic Boeing 757s, by 2016. Gogo earlier this month received FAA approval to install its product on Delta’s A330 fleet and the provider and carrier are in final testing.
