From now until July 15, 2021, Lotusmiles members only need to travel on 40 domestic flights operated by Vietnam Airlines

With carrier code VN (instead of the previous requirement of 50) to upgrade their membership tier to Platinum, 20 flights (instead of 30) for an upgrade to Gold and 10 flights (instead of 20) for an upgrade to Titanium. This incentive is applied to tickets with S, M, B, Y, U, Z, W, I, D, C and J booking classes.
