By plane
Chengdu Shuangliu International Airport is located 20 km 12 mi outside of Chengdu center and is one of the main air hubs in China, recently ranked 4th in passenger volume. It serves flights to/from most major cities in China, many smaller cities within Sichuan, and some international destinations including Amsterdam, Bangkok, Hong Kong, Osaka, Phnom Penh, Kuala Lumpur, Seoul, and Singapore.
Bus #303 operates between the airport and the city center, costing ¥10, stopping at the Air China airline office on Renmin Nanlu 2. Section next to the entrance of the Minshan Hotel (there is no bus stop! just look for a bunch of taxis/pedicabs, since they are also waiting for the bus. The last bus leaves the airport around 1AM.
Taxi fare from the airport to the city center averages ¥45. There is no extra charge for luggage or additional passengers. When going from the city to the airport, add an additional ¥10 to cover the toll on the Airport Expressway. If you intend to take a taxi from the airport, head for the domestic arrival area and exit the terminal where you should see the official taxi stand where you can queue for marked, green-and-yellow or blue-and-yellow taxis. Beware scammers and pirate taxi operators who are waiting to prey on foreign tourists with unmarked vehicles both inside and outside the terminal. Beware some who may sport official-looking, but fake, identification. The fare offered will often exceed ¥100, and if you bargain with them, you may find yourself sitting in the cab for a while until agreeing to raise the price back up.
