I think DSA was a bit of a wake up call for HUY, but when considering the catchment area, the majority of HUY's pax come from places that are actually closer than DSA, so it is actually easier for them to use HUY. What is wrong with HUY trying to compete, it has been successful so far. HUY-DUB flights are reportedly considerably outselling DSA-DUB.
