Some questions about airline flying in 70's/80's
I'd like to ask some questions about flying in 70's / 80's:
1. How many short / medium legs did a crew have to fly in a day?
2. What was a typical turnaround time during such a day?
3. Did a pilot fly with the same crew / 2-3 crews for a longer period of time or was it the same as now in terms of crew assignments?
4. Is the depiction from 70's / 80's movies correct when showing the captain standing in front of the passengers and giving a welcome "speech"?
Thank you in advance for all the responses. I'm very curious.
