I haven't done this myself, but that's my understanding of how it works.
Thanks - very helpful. And I take it there is nothing I can do about this?
Does this also work the other way round? There is a decent chance the EAU will clear on the return before the UDU on the outbound given the respective loads on the flights. Would that mean I lose the chance to UDU, or is the glitch only when UA clears ahead of CO

You should have a good shot as Plat on a W fare.
Thanks. Also very helpful.
