With an expected one flight daily, the route will increase the total number of flights between the two countries to over 50 per week, catering to growing passenger demand and expanding the national flag carrier's flight network in Northeast Asia.

A Vietnam Airlines representative said that the move marks a significant step in the firm's international expansion strategy while also fostering economic and tourism cooperation between Vietnam and South Korea.

The Nha Trang - Busan route becomes the airline's sixth direct connection between the two countries, alongside the existing ones of Hanoi - Seoul, Ho Chi Minh City - Seoul, Da Nang - Seoul, Nha Trang - Seoul, and Hanoi - Busan.
