Do you remember when flying in a commercial airplane was sort of fun and less like riding a Greyhound bus?

The first time I ever rode in a commercial airliner (the 70’s) my mom made me wear a tie!!!!
It was an event.
Everybody was polite, nobody spoke above a murmer, the attendants were helpful and generally pretty. People smoked too, but at the time I did not think of it as an issue.
In the same time period, I took a couple of trips on a Greyhound bus. It was pretty awful in contrast to flying. Many people smelled funny, mumbled gibberish and passed gas.
Last week, as I was flying to Chicago, I realized that flying has become pretty much exactly like riding the Greyhound bus used to be.
What happened?
