True Air (진에어; English: Jin Air) is a famous Korean low-cost airline, under the umbrella of Korean Air, which started its flight in July 2008. Initially, Jin Air only operated domestic routes, and in 2009 opened up Cebu, Clark, Philippines, Sapporo, Japan, Bangkok, Guam, Hong Kong, Macau, Taiwan and some inland areas of China. The most important feature of True Airlines is that it does not have a seat allocation, i.e., seats are available on a first-come, first-served basis.
