Does anyone know how the PA-BN service between LHR-DAL worked back in the late 60 and early 70s. I know the routing was LHR-ORD-DAL. I think PA operated the service, but I don’t know what BNs role was in the deal. I would also like to know if it was the same aircraft through to DAL and what type. I think a 707-320B, but not sure. Anyone know where I could find a 1969 PA timetable? Are there any Pan Am or Braniff old timers out there that can help?
