Yet another reason to come to China! (I say this as a fan of Chinese airlines.) Making a trip tomorrow from Beijing to Shenzhen. Four different airlines to choose from; a wide range of aircraft models; departures conveniently spaced through the afternoon. And fortunately the one factor I don't have to worry about is the price:
This is via CTrip.com, one of the main online travel sites. Yes, Ctrip often shows a range of fares; and yes, travel agents often have special deals for less than this official price. But this is s an interesting contrast to a similar array of US fares. In its own way it is weirdly comforting not to have to run the differential equations to see which is the best deal.
