TPAC routing to KSA

I am looking at booking a flight to KSA sometime in the next few weeks and have been trying to find the best routing options there. This routing listed below is the best option flying on UA. I would love to make this trip TPAC, however it is difficult to make a reservation to KSA with a TPAC routing on UA's website. Is there a better way to try to do this? This trip will be in J and would like to fly NH or SQ instead of LH.
