If you want to see the best example of how truly screwed up the UACO boarding process is, visit DCA. There, UA and AA flights are at adjacent gates. UA uses the post June "every elite is the same" rugby scrum, and AA maintains separation between F, exec plat, plat, priority access, and regular boarding.

I don't understand why management continues to insist on employing a broken process. Are they simply to proud to admit they were wrong?
