I saw, I think in the VOA thread, one comment saying the staff go out and get your boarding pass for you, bring it back into the airside area, and you can transit int'l to int'l. As with all things Vietnam, YMMV. If you do have a bp already, I'd just approach that desk and ask them where to go, cuz it isn't clearly marked that I know of where there is a stairway or elevator and security to get upstairs.

If you have an evisa and are willing to go through immigration, then your only question is about the length of lines at immigration, and those vary. I've been through many times, some only a few minutes, and others at the "rush hour" of many flights landing it took 30-45 minutes. Departure lines have also been pretty lengthy at times, but the newly remodeled departure immigration and security area has kept that moving quickly as of late, even when the lines are a bit long. Basically my point is that if you are going to go via immigration and going upstairs, it's again YMMV but biggest factor might be if the QR flight lands at the same time as some other widebodies.
