Hey, all -
I have here at the house an old Southern Timetable for June 1, 1975. This adds both DC-9 flights, but also adds M404 flights as well. I noticed there were only 9 flights in the DB for SOU, and I figured this would be a good way to add some more, as well as adding (maybe) some new cities for everyone to fly to.
On a side note, I also have timetables for both Empire (EM/EMP) and Altair (AK/ALT), neither of which are in the DB.
