Does anyone have a good way to find T-Fares that have no advance purchase requirements to 3-days. Understand that the majority of the T-Fares are 7,14 and 21 day advance purchase, but over the last year have come across a few that were of the zero to 3 day variety. Most Notably a T-Fare with 0 advance purchase for RDU-JNB for an impromptu South African Safari this past September. I have used www.farecompare.com/flyertalk to get an idea what fares are available out of a given market. But was wondering if any other FT'ers out there have any good tools and or suggestions on how to search?
