Lawrence - I had a short subscription to OAG's hardcopy years ago and never have tried their online service. As far as I'm concerned, you can see and find out more information online without having to pay for it. For example, the site I use a lot is www.itn.net - if you signup for an account, free, and turn on the "expert" mode, you can see all availability across airlines down to the fare basis. Since you travel quite a bit, you have a pretty good idea of what routings there are anyways. Most airlines now have timetables that can be downloaded onto a PDA anyways. With all this, I'm hard pressed to come up with a reason to pay for OAG, especially since I'm only a leisure traveler so it would be out of my own pocket.
