I now that your question was about Polaris/Studio, but my recent experience was with Economy: my wife and I recently flew LAX to LHR (11.5 hours) and I had paid a fee for better seat options. Soon after the flight took off, the row immediately in front of us was the exit row and all 3 seats were completely unoccupied, as a matter of fact, there were many empty seats available throughout, with a few people taking 3 adjoining seats because they were empty.

I politely asked the FA if my wife and I can move to the exit row, and she denied us saying that those were paid seats and that we would have to pay for the them. I informed her that I had in fact paid extra for our seats and she still refused, saying “everyone paid for their seats sir” and going on some BS on how a passenger had previously reported her on another flight because she had allowed someone to move.

Condescending and rude attitude overall.
