Not to be a downer, but on the return we flew QR J from JRO to DOH with a technical stop in ZNZ (some flights don't have the stop now, we had to stay on the plane) and it's the BarcaLounger style seats. No seat back or pop out IFE in J, they give you iPads that were maybe half charged, and the in seat power didn't work to recharge (the plug doesn't actually stay in the socket). From DOH to JFK we had great lay flats but it's a 14 hour flight. It's much shorter to fly via AMS if possible.
