I know there are people on the forum that have military aircraft experience.
However, I've worked for two major airlines and may have a different perspective on "flying" first class.
Plus I'm old enough to remember when flying wasn't Greyhound with wings and planes weren't always packed.
So with that preface, I can tell you that flying "first class" can be a real eye opener for a blue collar gear head.
Back in the day, before upgrades to first class were given for frequent flyer miles and an employee could actually get in first class flying "space available" or "non-rev", I did that.
Now people use frequent flyer miles and upgrade to first class.
Especially on long flights.
(Even with my federal licenses I could not get jump seats. The pilots guarded the cockpit jump seat for their fellow crew members who would "dead head".)
I remember one flight our VP of maintenance was in the seat ahead of me in first class.
He was chatting up the fellow next to him.
How did they tell each other what their profession was?
They showed each other business cards. I'll never forget that one.
Very low key stuff.
I suppose generalizations are a necessary evil in life. We all do it.
Sort of like the federal military.
i.e. By it's very existence political since it's an arm of the government.
Those people that "booed" in first class?.............
