EK77WNCL :
Whatever routes you may consider 'desirable' for your own purposes or reasons, an airline like EK, which is not a national flag carrier with a duty to serve a specific market, will look only at being able to make a profit out of a route. This does not equate, although there is a correlation, to filling the aircraft, that's the easy part.
Filling it profitably is the real challenge, and there are many reasons why this is so.
I'll thank you not to insult my intelligence,
Nobody is insulting your intelligence, what is questioned is your sense of the commercial reality of airline operations and profitability. You might want to read one or two of the classic books on the subject, such as Airline Marketing and Management by Stephen Shaw, or Flying Off Course, by Rigas Doganis (the man who f---ed up a couple of airlines!).
To answer your question about KTM, there are no EK flights to KTM loaded in the GDSs other than those operated by FZ/Fly Dubai.
