1966 EI One-Eleven departures from Dublin on a Saturday in 1966 when they were fully into service. All overnighted at Dublin.
0850 Paris
0925 Manchester-Amsterdam
1025 Manchester-Copenhagen
1130 Barcelona
1505 Dusseldorf
1845 Paris
So, nothing until 0850, one of the 4 aircraft doesn't even start until 1130, and only two of the four make it back to do second afternoon rotations. And Saturday was the busiest day of the week, less departures on other days. Incidentally, there were several flights a week to Lourdes in southern France (not on Saturday), a couple of which continued to Rome, bringing together several key ecclesiastical points that no other carrier connected.
Simpler days !
