I was looking through my Pan Am timetables and came across the Dec. 1985 one. On the map in the middle it has a few flights from DTW that are flown by Republic. In the ledged it says that the flights are "Pan Am Express operated by Republic Airlines." So my question is what was the relationship between Republic and Pan Am in the Mid 80's? Also there are 3 flights from ATL on Air Atlanta with the same designation. What sort of relationship did Pan Am have with Republic and Air Atlanta?
