For when an airline doesn't offer a map of the route as in-flight entertainment, is it possible to download maps to a phone to use to follow progress and identify towns etc when in flight mode? I can download Ordnance Survey but that is of little use flying abroad!
What I do is download my route on Google maps for offline use. You have to do it in chunks. Then when you are flying as long as you have a window seat your gps on your phone will still work and you can follow the entire route.
