No idea what your real question is here. UDU (now known as CPU) is completely different from the Y/B/M instant-upgrade fares. Those allow you space-available upgrades from a totally different bucket. Only when you get to the CPU windows does CPU matter. The fact that you might be missing from the airport upgrade list is separate from enjoying an immediate upgrade on an M fare as a 1K if PN is available.
