As I've referenced a couple times in other posts, Fiance and I are heading over to Europe for a week or so later summer. A 1K friend has graciously offered his SWUs for us to use. Here's the deal though...I'm a 1P, she's nothing. Is there a strategy that offers us the best chance at getting upgraded? For example, should we book on the same confirmation number? Any other tips that I'm not thinking of will be appreciated!
