We are back from Yangshuo with great suntan!
It was the first time we booked Spring Airline
which is a budget airline. They often offer 40-60% discount on the air tickets, sometimes even offer RMB99, 199, 299 tickets to some tourist destinations such as Guilin, Qingdao etc. Like Virgin Blue in Australia, they do not provide any free food on the plane in order to cut the customers cost.
Our experience with Spring Airline was pretty good - they are on time.
Check their website - Spring Travel where they offer not only budget air tickets for domestic and international travel, but also offer great holiday packages.
So it is an alternative to Ctrip when you want to book air tickets, hotels or holidays in China for both domestic and overseas travel.
