I never like UDU.
For those who fly mainly international, they'll always have enough e500s CR-1s and have better chance of upgrading domestic segments.
Not anymore with UDU.
For those who try to redeem int'l C/F saver awards, especially last min awards, finding domestic XF is really difficult now. Before UDU, you can find XF almost every BOS-ORD, BOS-IAD flight 1-2-3 days out.
Not anymore. Say you have ORD-HKG/PVG/PEK/NRT XF available, but nothing is available for BOS-ORD, no XF, no XY/NY. How do you get to ORD?
UDU was from CO. It's bad for me. And bad for many people. Ever seen 100+ people on UG waitlist for SFO-ORD/IAD? Good luck for you, even if you are 1K.
