The Line 6 of the Kunming Metro (Chinese: 昆明轨道交通6号线; pinyin: Kūnmíng Guǐdào Jiāotōng Liù Hào Xiàn) also known as Airport line (Chinese: 机场线; pinyin: Jīchǎng Xiàn) is a rapid transit line that connects the Kunming Changshui International Airport with Kunming's urban center.

The line entered into operation on 28 June 2012, and ceased operation temporarily beginning May 2016 in order to coordinate work related to the opening of Line 3 scheduled for early 2017.

Line 6 trains travels at speeds of up to 100 kilometres per hour (62 mph).

On the initial operation one-way trip will take approximately 20 minutes.

Line 6 opened to public operation on 28 June 2012 with two initial stations (East Coach Station and Kunming Airport), on the opening day of Kunming Changshui International Airport to serve the passengers from the new airport to downtown Kunming.
