Hoping those more informed and skilled at Saver Awards can help me. I like to think I am pretty good at this, but, I am struggling to figure out if this is possible.

I am looking pretty far out and just doing my pre-planning now. I realize that I cannot book awards for Jan 2017 yet, but that is my target (once available). I wanted to see if this itinerary is possible. I have been testing it via UA and ANA's websites (for bookable dates), but can't get it to form as a bookable itinerary.

Two passengers.

Business class (at least on the international legs).

DEN-DEL (via SFO, ORD, EWR, FRA, etc. really looking for the shortest timing possible).

Stopover in DEL for several days.

DEL-MLE (Ideally via BLR on AI. UA's website provides some crazy routings for this, where ANA shows availability on the simple route via BLR.)

Destination MLE for several days.

MLE-DEN (Ideally via FRA on LH/Cityline, but MLE-IST to any US entry point for TK is fine too, then to DEN).

Has anyone done this (or similar)? Of course UA's website cannot handle this. ANA's does better, but cannot confirm an itinerary (may be their rules).

Thoughts, help, etc... I realize I am looking far out for this, but if this is not possible, I would like to move on to other options.

Thanks for your help.
