...and, as a follow-up, do I understand correctly that it has once again become possible to request an eUp within 24 hours of departure?

What I'm trying to do is move off my upcoming, packed, YVR-YOW, onto any of several YVR-YYZ-YOW or YVR-YUL-YOW options that are O9 N9, and eUp myself and Mrs. YOWgary to PE without co-pay.
