Renner finds love in the air. - Jordan Strauss/WireImage
So when celebrities meet people in an "ordinary" way, it's always a bit jarring. When Michael Vartan met his future wife in a parking lot a few years ago, it was notable in his refreshing normalcy (not that picking someone up in a parking lot is normal, really, but you know what we mean).
Renner and Montgomery were on the same flight from Vancouver to Los Angeles. They were later spotted in Berlin together and then in Los Angeles' Runyon Canyon this past week.
How exactly this plane meeting went down is unclear. But this should give everyone hope that if you're sitting next to a famous person on a plane, you might as well try your luck. Though, erm, of course it will help your cause if you happen to a be a beautiful, young, up-and-coming actress yourself.
