For the reason, one should ask that the GUC not be applied to the short segment until the long segment clears.
In the other example, though, burning a GUC for SIN-NRT while not clearing NRT-USA isn't too much of a waste because SIN-NRT by itself is a pretty long flight.
Delta markets CRJ 700's, 900's and EMB 170/175's on the west coast, and no CRJ 200's. So all west coast regional flights have first class. First class on SAN-LAX is just 1-2 instead of 2-2 seating and a PFB.
