Oh, pretty typeface! LH Line1 Sans comes from the one-person creative studio Lufthamn Studio (you can see it in action on that site, as well).
Here is a sample image, via the League of Movable Type’s tumblr:

And of course it is licensed under the Open Font License.
I’ll be honest, I am probably going to use this very soon. ^_^
