I'd try again.
Here's AA's official release: http://www.aa.com/i18n/utility/dragonAir.jsp

In terms of pure routing, the shorter flights will be in this order DEL<AUH<HKG<BKK.

All of the above carriers' business class will have an arrangement with at least 2 seats together, most likely in the center.

I'd say DEL-KTM should cost ~ $150 roundtrip on AI a month in advance and you could earn UA miles too. Not worth redeeming those number of miles to me.
