We flew threw SGN last year for the first time......Landing didn't seem like a big issue albeit it was around 10:00 p.m. at night. Just normal process with a little waiting getting through..........coming home was a whole different story! Thank goodness we arrived to the aiport early and didn't dwiddle around before we checked in. We were flying out in the morning on Korean and we checked in immediately - Within about 15 minutes waiting to get checked in the line grew to at least triple the size.....waiting to get through security and such was crazy......I believe we were there about 3 hours before our flight and literally walked to our gate and had about 15 minutes to spare.
