Can India-Canada/US flights fly over western China?

Wed Jun 08, 2022 2:19 am

There is something I am wondering about India-US flights.

Certain flight route such as DEL-YVR (AC) and DEL-SFO (UA) often flew a flight path over Pakistan, Afghanistan, Kazakhstan, and then east over Russia to North America.

Are they allowed to fly over western China? Does China allow Indian flights it's airspace in this area? It seems like a flight path from India over western China, Mongolia, and through Russia would be quicker to North America.

I often see airlines like QR and EK flying asian routes through Pakistan airspace to China on Flightrader24. I wonder if flights from India to the west coast of North America could use the same airspace.

Much of China's airspace is heavily controlled but that's not the reason as while I'm typing this there are no fewer than 3 EK flights flying east over western China from DXB to KIX, ICN and NRT. Flying over western China from India would involve flying directly over the tallest mountains in the world in the Himalayas. Additionally AC and UA won't be flying over any Russian airspace for the foreseeable future so the point is moot. AI185 787-8 from DEL to YVR doesn't face the Russian ban but still are flying west over Pakistan largely avoiding the Himalayas before heading north for the polar route over Russia and Alaska. Western China would be a diversion for them.

Exactly what AC did for DEL-YVR:

Or if you mean Tibet, I don't think any airline normally fly over the Himalayas.

If you mean going over Tibet, Tibetan flights in China require specialized plateau-equipped aircrafts. Mostly due to oxygen requirements.
For example, if you hava a cabin decompression over the ocean, you could descend to a lower, breathable altitute. The oxygen generators only last ~15 minutes.
You can't descend to such altitudes over Tibet without hitting mountains (or getting dangerously close). Thus additional oxygen supply is required.

The Tibetan airspace is generally off-limit for international carriers or even Chinese carriers not flying to Tibetan destinations.

Sometimes India flights to places like SFO does fly over China but they take a southern routings (i.e. fly over to eastern India, northern Myanmar and then cross into Yunnan province of China).

The only international flight that fly over the Himalayas is the CTU-KTM service:

You need that for Northwestern China also. This included most flights from Europe to the South China Sea region pre Ukraine war.

Even for inbound flights to India, they'd still have some hurdles. No Tibet, Afghanistan, or Russia. Would a route such as ATL-MAA depart eastbound or westbound? Maybe they could use the jetstream if west but it would still be difficult. I don't think even A 350-900ULR could handle such a route comfortably, at least on the MAA-ATL leg.
