Love... and money (and Miles!)
My g/f currently lives 5000 miles away.
I also travel a lot of work, but this is the first time I've made Platinum...
(and ok, it took a MR to LAS in Dec to round it out too, but I'll sure use those systemwide upgrades)
We'll be moving together soon, so I'm not sure I'll keep it up, but I can't say that I'll exactly get misty-eyed thinking about those lost BIS miles.
