The schedule times of UK holiday (and all other) flights in 1985-2005 are to be found in an annual publication called "Airport Times", by Airtime Publishing, put together by a group of enthusiasts from the Midlands. Done it seems each Spring, so more up to date than brochures, but really shows the game plan for the summer rather than individual weekly variations. It seemed to get almost all the holiday charter series, and even showed the principal charterer. Secondhand ones periodically turn up through Internet dealers or from traders at airshows etc. There was even a competitor for some years called "Flight Routings", which didn't seem as accurate but could fill in odd gaps in the other. They died out when Internet information came along.
