When I went to the old timetable website just now:
https://www.aa.com/i18n/travelInform...cTimetable.jsp

... a survey popped up asking what type of user I am (traveler, travel agent, airline employee), along with: "What do you use the AA pdf and pc timetables for?" and "Why do you use the AA pdf or pc timetable?"

Might be an opportunity to directly register your disapproval, if you're upset that these are gone.
