If you booked two one ways, you do it separately and pay twice. If you booked a round trip, you pay once, but you pay 90k miles even if you only get J one way.
Note that if you pay for J, you can also sit in PY if it's available, and request an upgrade at the airport into either cabin.
I booked the flights using a multi city reward, so I'm not sure if that is different from two one ways.
Also, I'm not sure what you mean by paying for J and sitting in PY and requesting an upgrade? could you clarify please?
