I'm sure this answer exists somewhere in these 161 pages, but I'll pay for my laziness by adding the answer to the wiki once I have it.
I'm flying with the Mrs. tomorrow, and we are waitlisted for PE-->J using her (50K) eUps.
Does this place both of us on the waitlist with her 50K priority, my SE priority, or me with mine and she with hers?
I appear above her on the waitlist, but this would also be true if sorting alphabetically.
