I was poking around on ua.com today and noticed some route maps I hadn't seen before. There are now two PDF files (direct from Hemispheres) that provide maps with route lines. Pretty great, if you ask me.

I believe this is a recent upgrade (my FT search found a thread from a couple weeks ago where airlineroutemaps.com was still suggested as the only/best option). Google cache says it was up as of a week ago.

Here's the route maps page.

Here's the North American map and the International map.
