Ethiopian Airlines has placed an order for nine Boeing 787 Dreamliner jets amid growing demand for long-haul travel, the two companies announced on Tuesday.

Global airlines have been ramping up orders for widebody jets as international travel demand grows and carriers seek more fuel-efficient aircraft to cope with rising operating costs and capacity constraints.

Ethiopian Airlines plans to use the 787-9 jets to expand its network beyond the 145 international destinations it currently serves.

“We will continue to acquire more aircraft and adopt the latest technologies as part of our strategic vision to advance sustainable aviation,” CEO Mesfin Tasew said on Tuesday.

The airline also completed the purchase of 11 737 MAX narrowbody jets, which it had committed to buying during the Dubai Airshow last year.
