Thanks for this great tool. I am also interested in timetables/schedules. Where do you get the timetables for airlines that do not expose their schedules/timetables? For example TAM Airlines (carrier = JJ) does not have timetables on their web site but I see that your tool does have the routes. Would you be so kind as to reveal the source(s) of your data? Finding schedule data as proven to be more difficult than I thought. Thanks again.
