Yeah, it works only between iOS-iOS or Mac-Mac for me. Rarely works cross-platform.
I even called AppleCare to troubleshoot, and the level 2 tech I spoke with said that it "might not work reliably" on pre-2014 devices. I pointed out that Apple's website claims compatibility for post-2012 devices (my MBA is 2013), and he said I was being argumentative. He also couldn't cite any documentation for his 2014 claim.
I now use Dropbox instead of AirDrop, which is inefficient—especially given my slow upstream connection—but at least works reliably.
