In 2020 the state-owned carrier sold five Airbus A321 aircraft for $7.4 million apiece.
Selling jets was part of the airline’s plan to restructure its fleet and increase post-pandemic income.
The airline now has a fleet of 94 jets, including 65 A321 jets with an average age of just over 9 years, according to aircraft data provider Planespotters.
Vietnam Airlines served over 10 million passengers in the first half of this year, up 23.6% year-on-year.
Its revenue rose by nearly half to over $1.91 billion, almost the same as in 2019.
