I stopped flying when I was treated as a potential criminal.
When I was a kid, flying was fun and an adventure.
The passengers dressed up (suits, nice dresses, nice shoes). The agents, flight attendants, airport staff were top notch. Even the airports were exciting. The service was outstanding.
Today, the employees are exhausted, you are treated like a felon by the TSA, and most of the passengers are rude and complete slobs.
