Taiwanese Star Alliance member EVA Air has signed a firm order with Boeing for four additional Boeing 787-10 Dreamliner aircraft, the largest 787 Dreamliner variant.

The order has a list price of US$1.9 billion, EVA Air has said.

EVA Air currently has 11 787-10s in its operating fleet, plus one more on order from a previous order for a total future fleet of 16 787-10s.

The airline also has four smaller 787-9s in its current operating fleet, plus nine more on order from Boeing.

At the moment, EVA Air predominantly operates the 787-10 on its services between Taipei and Japan.

Taoyuan-Narita currently sees the 787-10 deployed three times a day, and so does Taoyuan-Kansai (Osaka).

EVA Air also deploys the aircraft twice a day between Taipei Songshan and Tokyo Haneda, as well as on select services between Taiwan and Hong Kong.

EVA Air’s 787-10s currently feature a two-class layout with 34 1-2-1 business class seats, and 308 3-3-3 economy class seats.

Going forward, the current 787-10s will be refurbished to feature a premium economy cabin and all new deliveries will have this product factory-installed.

In other EVA Air news, the airline recently resumed its Kaohsiung-Hong Kong route, operated with regional A321 aircraft daily but expected to increase to double daily later this month.
