Generally two or three weeks ahead works for getting decent airfares, unless you're travelling at a holiday period.
There can be fairly big seasonal differences in fares, with discounts being greater in the winter than summer. Also, discounts tend to appear on busy, well-travelled routes. Flights in and out of a small place like Huangshan, for example, often don't get discounted that much. |

How do you locate the train # for the 350 KM departures?

All the HSR trains are running at 300km/h, the only difference is that some of them stops at only one (Nanjing) or two (Nanjing/Ji'nan) stations (~4hrs50mins) while others have 5+ stops (5hrs30mins~6hrs).
Most, but not all, double digit trains stop in Nanjing and Jinan only. Triple digit trains have at least 3 stops. |

Which trains were speed up? I just checked Shanghai-Beijing on 12306, and the fastest trains are still 4:48 (G2, G4, G8). Incidentally, G8 is a welcome addition to the schedule because it makes it possible to work an entire day before leaving.
Regarding the decrease from 350 to 300, this happened after that accident in ~2010, and safety was the stated reason for the change. However, since that accident had nothing to do with the speed of travel, I have long suspected that saving money was the --behind the scenes-- reason. During testing of the Jing-Hu Line, I recall reading that some trains were run at very high speeds (e.g. 450). |

Not exactly
G6 stops at Najing & Ji'nan G## < G20 usually only stops at Nanjing & Ji'nan, while G12 has 5 stops Others 5+:p In the original Jinghu HSR schedule, 2-digit trains adhered to the 2-stop convention, but this went out the window when they starting trying to optimize things. |

I guess for trains it's quite similar than with cars: After a certain point of speed, consumption goes up so much it's simply not worth it.
I can drive my car at 80km/h or 120km/h for about the same consumption (5l/100km) - when I go up to 150 or 160km/h, I'll have an increase of about 20-40%, still reasonable for the speed I gain (compared to 120km/h) - I gain about as much time as the extra consumption is. But if I press it above that, consumption does increase much more than the raw speed gain. I can imagine that 300km/h for a train is about the same as 150km/h for my car. Go above it, and it uses much more electric power than going just a little bit slower. And considering the HSR operator probably got told to be more efficent, they'll keep it that way, unless going at higher speed gets them more money. |
