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
EUA is the finicky one. UDU doesn't care if you're in-sync or not.
