Airspace over Indian Himalaya

For example the flight from Almaty to Delhi (KC907) takes a route to the west, then over Afghanistan and then takes a sharp curve to the east after Peshawar.

Do you know if that's the usual route?

An interesting question, would guess some disputed parts are closed and therefore easier for air force jets to play the Himalaya games, as seen by many trekkers.

Do you know if that's the usual route?

I wanted to take this route since assumed very nice views (in fact Almaty and Delhi are nearly on the same meridian). Looking several times on the flight radar online have seen that the route has this unusual deviation. I know that this can happen sometimes. For example few years ago a usually very exciting PIA flight from Beijing to Islamabad (I have used it a couple of times) took a route straight to the south and then over Burma, Kolkata and Delhi. Caused a 2.5 hours delay. The cabin crew told this was due to high fog over Karakoram.
Interestingly, according to FlightAware a Korean Air flight from Nairobi to Seoul takes the route over Himalaya. The available radar coverage stops few hundred km past Islamabad thus the fligt cannot be followed live.

I asked because a temporal close could be due to many reasons.

If it isn't temporal, I would research if the airspace border between China and India is closed (as it's the land border). In other words, is there any flight that goes directly from Chinese airspace to Indian airspace? Direct flights from India to China enter Chinese airspace directly from Indian airspace or make it through other airspace (e.g.: Nepali)?
