Vietnam Airlines will start flights to Denpasar and Phuket and resume Da Nang-Bangkok services from 27 October.
The carrier will begin three-weekly Ho Chi Minh City-Phuket and five-weekly Ho Chi Minh City-Denpasar, with plans to raise this to daily at a later stage. Its daily Da Nang-Bangkok service will also resume at the same time.
Cirium schedules data shows that Vietnam Airlines last operated on the latter route in March 2017. Bangkok Airways and Thai VietJet Air also fly between Bangkok and Da Nang.
Vietnam Airlines will compete with VietJet Air on the Phuket and Denpasar routes.
