We will be flying from Guilin to Kunming in April. I have been checking the price each few days with Ctrip but it as remained the same RMB 840 plus taxes of RMB170. I don't know whether to book It now or wait until closer to the time and hope it gets cheaper. Our dates are not flexible as we have booked a hotel in Yangshuo and are meeting up with a tour group in Kunming. As these are smaller airports with less flights than the bigger centres I was wondering whether they ever discounted flights and whether even the above quoted prices might get booked out and we would have to pay even more if we leave it too long..
