I used the PDF to get an idea of travel destinations and routes, but I can't say I miss it since it was rarely accurate about future schedule changes, regardless of whether I was looking at times that were 11 months, 3 months, or even 3 weeks in advance.

Unfortunately the oneworld mapper also has stale info about timing and routes. It's not uncommon for it to show me a route but then it can't find and flights that run on a particular segment.
