Cathay Pacific is the flag carrier of Hong Kong and is among the oldest airlines in Asia. The oldest airline in Southeast Asia is Philippine Airlines, which was founded in 1941, while Taiwan’s China Airlines began in 1959. Mainland China’s Air China only started in 1988. The airline is now around 80 years old, and over that time, its liveries have undergone significant changes and are now unrecognizable from what they once were. During this time, green has become the color of the airline.
