Japan Airlines (JAL) plans to place its code on Vietnam Airlines' Osaka Kansai-Hanoi services from 13 January as the two carriers expand a code share agreement.
JAL will suspend its existing daily flight between Osaka Kansai and Hanoi from January 11, says JAL.
Vietnam Airlines operates services between Osaka Kansai and Hanoi five times a week on Airbus A321s.
JAL already code shares on Vietnam Airlines' services between Fukuoka and Ho Chi Minh City, Fukuoka and Hanoi, and Nagoya and Hanoi.
The Japanese carrier also operates services between Tokyo Narita and Ho Chi Minh City and Hanoi, adds JAL.
