Seeing each leg's fare in points when changing RT itinerary
 

I am trying to change an award ticket I booked for my wife, and I want to see how many points I was initially charged for each leg (not the total). Is there any way to do this aside from calling reservations and asking?

I don't think the award price is broken down by leg at any time. Neither are cash fares. Only the security fees are by leg.

Assuming you bought a RT fare, not that I know of. The point details in the emailed receipt or from your RR account only show the complete point total.

Looks like a call into WN.

Why not just click "change itinerary", then select new flights for the one leg, and see if it shows a net increase or decrease in points? You don't have to go through with the change if it's a point increase.

I "changed" some award tickets to the same flights last night. I thought the fare on the outbound dropped by a few points but couldn't be sure. Then it showed me a 900 point refund per ticket before I confirmed the "change".
