Low-cost Vietnamese carrier Vietjet and Japan Airlines reached a formal agreement on Tuesday with the aim of meeting the growing demand for air travel between Japan and Vietnam.

The partnership is intended to improve customer convenience and the quality of operations and services, while also enhancing the corporate value of both airlines, Vietjet said in a press release.

Japan Airlines is already operating daily non-stop services between Tokyo (Narita), Ho Chi Minh City and Hanoi respectively, as well as between Tokyo (Haneda) and Ho Chi Minh City.

Japan Airlines and Vietjet have agreed to begin code-sharing on all flights between Japan and Vietnam.

The cooperation will include the Japanese carrier’s domestic flights and Vietjet’s domestic flights, as well as services between Vietnam and other Asian countries.

These add-ons are expected to improve customer convenience, according to Vietjet.

The two carriers will explore further opportunities to develop their partnership in various areas, including a frequent flyer club, aircraft operations and maintenance as well as ground services and training.

“The launch of this partnership with Vietjet represents a significant milestone for the two airlines to provide customers with better access to destinations between Japan, Vietnam and beyond,” Japan Airlines executive vice president Tadashi Fujita said.

Vietjet managing director Luu Duc Khanh underlined Japan as the carrier’s key market in its plan to expand its flight network in the Asia-Pacific region.

“The partnership between Vietjet and JAL will stimulate travel between the two countries as well as developing the two airlines’ relationship,” he said.
