onedog,

I like OAG for planning my RTW trips. My employer subscribes to the Worldwide edition, which is thicker than a NYC telephone book!

In any event, it does seem to provide the most complete listing of flights between city pairs...and when you're looking at a lot of different trips between a lot of different potential cities, I still prefer the old-fashioned paper guide.

The worldwide edition also comes with bi-monthly supplemetal materials (another book) that has visa and passport info., plus seat maps for many different airlines and airplanes from around the world. Like every resource--electronic or hard copy--the OAG is not absolutely perfect. However, for my purposes (which includes A LOT of int'l travel), OAG seems to fit the bill.

If you fly pretty standard routes, then you're probably better off figuring out which airlines fly between those points and picking up their own, free timetables...or use their webpages to search fares and times.

Just my two cents.
