Unfortunately from this side of the world, booking a discounted Y fare is very difficult. In the past, I used Ctrip, but payment always been an issue. I just don't have that much cash in RMB, I mean I am talking about 20-30K RMB just for domestic flights for each of my trip (sometimes involves colleagues as well).

And, at this side of the world, corporate travel agent plays a big role in travel planning. Officially, we have to put through every single journey through them. And they always only capable to provide full Y fare, plus 30 pounds commission charge for each domestic flight!

Now I ask my friends in China reserve F tickets for me before I travel, and I pay on my company credit card once I got. To be honest, even with the 50% premium for F fare, the overall cost actually is cheaper than Y fare through our travel agent. Madness, isn't it? But we have to live with this. That's why there is no reason I would go for a Y fare in China, even with discount.
