Inmarsat (LSE: ISAT.L) has signed a contract to provide high-speed inflight connectivity services for passengers onboard Lufthansa’s European continental fleet.

The contract follows the Memorandum of Understanding announced last month, formalizing a ten year strategic partnership and a contract framework extending the service to other airline brands in Lufthansa Group.

Inmarsat will equip more than 150 Lufthansa airlines aircraft with Global Xpress (GX), with additional Lufthansa Group aircraft being added in due course. The first of the aircraft will be equipped and tested early summer 2016. Lufthansa will be trialling the European Aviation Network in 2017.

Passengers of the Lufthansa Group will be offered in-flight connectivity that matches the quality and speed as when on the ground.
