Is Urumqi really an international hub? I can’t imagine anyone flying through that city for any trip that didn’t originate or terminate in China. Chengdu is much more of the hub these days.
I flew through it once, and now I will never do it ever again...
I do feel that bigger name European airlines opting to reroute flights to China through Chengdu had all of above in mind
There used to be flights through Urumqi on EU-China routes just 2 years ago with stops just in it or in Almaty by quite a number of airlines.
The accursed flight I was on was done by China Southern
