Changing award ticket routing, possible?

[John316]

Hello,

We have 2 LHR-SIN-LHR Business class redemption seats. I took this routing because originally there was no availibility on the EWR-SIN (we are coming from new york). Now there is availibility from SIN-EWR on the return leg. Is it possible to change the routing to LHR-SIN-EWR?

Thanks so much
