UpgradeMe:

A helpful piece of experience. I was told otherwise. However, I sincerely wonder whether your situation was unusual, or the agent was wrong, since this would be a significant issue.

I wonder if one of the previous posts, where there were two separate emails, is indicative of a per segment upgrade. Would think that the system processes everything based on flight, not a person's itinerary. Any other experiences out there?

So far 4/4 with EUA, myself.
