Booked on Sunday(May 20th) ORD-GRU on a 777-200 with the new Polaris Seats. Will report back as it seems there isn't too many of these out there. Seated in 1L. So far the flight back on Thursday May 24th is still in the old configuration. I followed the advice of the 77W thread as it seems they are similarly set up. We'll see how it goes...
