From this quote it appears it is a non-domestic airline, currently flying. So I would guess maybe British Airways, or Cathay Pacific?

One of them recently retired after 20 years flying for the most storied name in commercial aviation, while others work for less glamorous domestic U.S. airlines.

A lot of them seem bogus. Especially the "wheels up" pay thing, inventing a problem to get more airtime pay, and "I'm as clueless as you are" on what you're flying over. If it's a FA's frequent route, they won't be clueless.
