Can verify that.
As an SE,I booked seats to Europe and back in discounted J and Mrs.acysb87 on a J reward(IKK).When I tried to book her into 1F on a Dash a/c,AC wanted another $20.00 for the premium seat.

If she was on same PNR,no extra charge.If I had a family of 4 on same PNR,there would not have been an extra charge.
