The airline plans to operate the wide-body aircraft Airbus A321 on the route with a frequency of three flights per week running on Mondays, Wednesdays, and Fridays. 

From October 30, the carrier will move to increase the weekly frequency of flights to five on the route.

Vietnam Airlines is currently operating another trans-Indochina route, Hanoi-Vientiane (Laos)-Phnom Penh (Cambodia)-Ho Chi Minh City with a frequency of seven flights per week, making use of the Airbus A321 aircraft.

The resumption of the new route is expected to offer many convenient options for travelers during their trips to global cultural heritage sites, and to help expand Vietnam Airlines' international flight network.

These routes will also actively contribute to the overall development of the tourism industry in the region, as well as trade and investment promotion, and cultural exchange between Vietnam, Laos, and Cambodia.

Vietnam Airlines has operated routes from Vietnam to Siem Reap in Cambodia since 2000 and to Luang Prabang in Laos since 2006. In 2019, the largest Vietnamese airline transported nearly 400,000 passengers on the trans-Indochina route.
