And while I’m not the only journalist on the flight, I am the only one who has been sat in economy for the nine thousand and one mile journey.

Do the English really speak this way: "has been sat"?

Yes. "Has been sat" as opposed to "had been sitting" or "has been sitting" is more Sussex dialect than anything

American English tends to use the simple past more often

It is awkward seeming but correct.
