Too many restrictions and more importantly, doesn't work for Dashain-Tihar. Just checked, and it says 1970 from DC to Ktm roundtrip during Dashain-Tihar season. If you add the cost of domestic flight from other cities to DC, that'll bump up to 23-2400. Even if you get the 11xx.xx deal, you'll be paying ~1500 total if you are not in DC and will be missing Dashain/Tihar on top of that. So, it's basically not much of a deal, is it?
