I imagine for you it's more or less impossible to start over now, so it's pretty lucky that they've been good to you so far!
I kind of got tired of traveling so much and stopped doing it, though. Traveling for work (just meeting people in other offices) kept my status until about 2017. Then I stopped doing that, and now I'm just a bum with no status on any airline. That's about when the mileage-based gravy train came to an end anyway, so I'm not that upset about it. It is good to be marked in the system as someone to pay attention to (got many free upgrades on Cathay Pacific for no reason back in the day), but you are still treated well when you buy a first or business class ticket even without status.
Sure sometimes flying entails hassles and inconveniences but not every airline is awful and certainly not every employee lacks compassion.
Another time, I was walking out of the Admirals Club at DFW to board my flight. One of the agents came running out to tell me I was walking in the wrong direction.
But, it's not always great. I had an award ticket in 1st class out of LHR, and they didn't clean the plane at all. The tray table had sticky soda all over it, and the plane was filthy. Miserable flight.
Another time, I had an upgrade to 1st class on a domestic flight, but the TSA didn't like my bags and did an extensive check (I must have been on some list back then, it happened a lot). I arrived way late to the gate, and lost my seat. Ended up flying back home in a middle seat in the last row. It was miserable.
So, it's a mixed bag, but generally good. It's hard for such a large company to offer consistency.
