EVA Airways has signed an agreement with GE Capital Aviation Services (GECAS) to lease four Boeing 777-300ER aircraft.
The deal comes after the carrier leased two B777-300ER aircraft in February this year.
All six aircraft are scheduled for delivery in 2016 and 2017.
The B777-300ERs are intended to help EVA modernise its long-range fleet with high fuel-efficiency, more payload capabilities and additional flexibility in serving the nonstop routes.
GECAS president and CEO Norman Liu said: "We have a strong and positive long-term relationship with EVA that dates back more than ten years ago.
"We are delighted to help them upgrade and expand their fleet with the latest long-haul aircraft available."
