Imagine if you worked for that airline as a flight attendant or pilot. You would never know when you're supposed to go into work!
Cancelling flights that undersell is difficult on operations, because it puts planes and pilots out of place. If a plane is supposed to go Hanoi, Da Nang, Saigon, Busan, and back to Saigon, and they can’t really cancel the earlier legs. And even if there practices are closer to what you say, they are still essentially selling tickets on flights they do not plan to operate, and for the passenger that comes out to the same outcome.
