Cheapoair.com is cheap because the route is via DELHI.. Sometimes its a too-much hassle going through Delhi. Dhotis will ask for your Indian VISA, you'll have to look for ur luggage in Delhi and find a hotel to stay overnight in Delhi. Dhoti bhais (Rickshawala's) will try to rob you if you're alone.
Dhurmus,
Try via HongKong (Cathay Pacific and Dragon Air) which will be around "1150--1300"..pretty much same as going via DELHI and "Cathay Pacific" is a 5 star airlines, very good service. Transit is not very long either. That way you avoid long-tiring route of going via DELHI and also long overnight layover in Delhi..One more thing, It would have been cheaper for "Khalisis" because one of the flight is operated by "Nepal Airlines". I shouldn't write any bad stuff about my own "Nepal Airlines" but i am forced to. With "Nepal Airlines" you never know when you'll fly. It is delayed 70 % of the time, Sometimes you may even miss your connecting flight and wait another day.!!!
Another suggestion is try "Etihad Airlines" which would cost you around $1400. The service is really great. I am sure you'll enjoy the trip with Etihad. You'll not regret for "200 dollars" more that you will pay going from "Etihad Airlines".
Good Luck.
