In the late 1960s and early 70s I used to affordably fly as a working teenager. It ran me sometimes $15 each way between PWM and BOS on Northeast Airlines' DC9s or Executive Airlines' Twin Otters. I could afford a Summer trip from PWM to HYA on Execuive, annual trips on United between BOS and FWA via CLE to visit the grandparents each February break (paying for my own ticket). My dad traveled on business twice monthly on Mohawk from BOS to UCA. I took advantage of a couple weekend specials on Mohawk for travel to any city to which they flew for a whopping $39 - good on any flight between 6PM Friday and 6PM Sunday. It was an era when Northeast flew DC9s into EWB, FH227s into LEB and EEN, and when LEW had commercial service to PWM and BOS. There were annual Jimmy Fund flights (TWA, I think) for a penny-a-pound contribution that ran to some thirty minutes generally from take-off to landing for the fund-raiser.
I was a working teen (line boy at BEV and yardwork) from a middle class family and flying didn't seem like an extravagant luxury or tremendously expensive, if I could afford it.
I've always wondered at the change and what happened to the world that seemed so routine back then. Anyone offer insight? It couldn't be simply the fares (see above). There was airline service to Podunk and back on everything from DC9s, 727s and Bac 1-11s to Navajos and Twin Otters. Where did it go and why? A different demographic? Certainly not security only. All this existed well before 9/11 and the TSA. Changing demographics and travel patterns?
