Vietnamese budget airline Vietjet and SpaceX’s Starlink will provide free high-speed Wi-Fi to passengers, starting with 120 aircraft.

In a statement on Wednesday, Vietjet said the two sides have signed a strategic agreement for the move. No financial terms were disclosed.

The deal was signed in New York, on the sideslines of a U.S. working trip visit by General Secretary-State President To Lam. Vietjet signed the deal through its group companies Galaxy Holdings and Galaxy Telecom.

The deal builds on an initial agreement the carrier signed with Starlink Services Vietnam in May, Vietjet said.

In the first phase, Starlink will be installed on 100 Airbus A321 and Boeing 737 jets and 20 Airbus A330s, with future deliveries also equipped. The aircraft will serve domestic and international routes.

The satellite service uses a low-earth-orbit network to provide high-speed, low-latency connectivity, including over oceans and remote areas. the Wi-Fi would be free to passengers, a distinction from the paid in-flight internet common on many airlines.

Prior to the agreement, Vietjet board approved a VND250 billion ($10 million) injection into its wholly owned Galaxy Pay unit in August to help fund Starlink infrastructure.

Nguyen Thi Phuong Thao, Vietjet’s chairwoman, said the service would let passengers work, stay in touch and be entertained in the air much as on the ground.

Tim Hughes, SpaceX’s senior vice president for global business, said the cooperation can extend the Internet service Starlink already provides to homes and businesses in Vietnam.
