I fly standby, so my trips start with the days I'm off and the airlines my pass covers. I need to see every flight I could list on, and a backup in case I don't get on. Flight searches start with a destination, so none of them could show me that.
WhatFliesWhere shows everywhere you can fly on the dates you're free, on every airline, and where your points or staff travel privileges can take you.
I tried a paid flight data service first, but flights were missing and seasonal routes had no dates. So I built my own system from scratch, combining many sources. Airlines add, drop and change routes every week, and keeping up with them is most of my work.
