Yes, I know. Vietjet air is still significantly cheaper as a cash fare.
Then you're not going to get the most value from miles. In fact, i'd say flying Y in long haul is actually worse
Worse from what point of view ? Not from a cost point of view, it costs fewer points or fewer dollars in every case I have seen so far.
It's also possible to accumulate UR by shopping online , not so for MR and SPG
Certainly an advantage, but that doesn't factor in to the redemption value (cpp), only more flexibility in earning the points.
