Indeed. With all the planning and tweaking I have been doing recently, the thought had occurred to me. The problem is getting the schedules. Once you have that, putting together some sort of rudimentary program shouldn't be too hard. Both Star Alliance and oneworld use the same application for their electronic timetable, so I suppose the data files could be reverse engineered, but I'm too old for that kind of thing.

The Star Alliance RTW app is still in beta AFAIK, and it does get pretty confused, but at least they're working on it.
