And on the topic of married segments, I once had some KF agent say that because I had SIN-HKG on SQ872 connecting to SQ2 HKG-SFO, I can’t “break off” the SQ872 and just fly SQ2 only. After I insisted, voila! - they suddenly could! Which leads me to believe they actually can do funky things if you insist / demand that they see sense.
