You can't. It is a route I have used UA systemwides on before they went to H fares and then dropped down to W fares. That was the first route I thought of where there is a significant price difference to buy a fare you can try to use a UA systemwide on. I posted it to show how much more you need to spend there to try and use systemwides.
The second example I posted (ORD-PVG) is a direct comparison.
