I wouldn't read too much into public sentiment which is riddled with exaggeration, rumour and fear mongering . The Saudi public is good at making mountains out of mole hills.
Saudia isn't spared either. You should hear some of the stuff being said about the "Tabouk crash" and other sensationalist stories.
They are burning lots of cash (NASair likewise), but I think the investors are committed to the project enough for them to weather the storm. They have been very vocal in their lobbying regarding fare caps, PSO and SV's fuel subsidies, and if rumours are to be believed they (and NAS) may be getting a reduction in PSO routes.
