Lotusmiles members can combine Cash & Miles to upgrade their service class or purchase additional baggage on domestic flights departing from Noi Bai, Danang, and Tan Son Nhat airports within 8 hours to 1 hour prior to departure.

Upgrades depend on the specific fare classes of the original tickets and are subject to seat availability. Additional taxes and fees may apply. Upgraded members can enjoy benefits based on their card tier, and additional miles according to the original ticket purchased. They are not eligible for Business Class baggage or Lotusmiles Lounge policies.
