Air India is the flag carrier airline of India and the third-largest airline in India in terms of passengers carried. It is owned by Air India Limited, a Government of India enterprise, and operates a fleet of Airbus and Boeing aircraft serving domestic and international destinations. The first logo of Air India was a centaur, a stylised version of Sagittarius shooting an arrow in a circle representing the wheel of Konark. The logo chosen by founder J. R. D. Tata was introduced in 1948 and represented the airline until 2007. On 22 May 2007, Air India and Indian Airlines unveiled their new livery consisting of a Flying Swan with the wheel of Konark placed inside it. The flying swan was morphed from the centaur logo and the chakra was derived from Indian's erstwhile logo. On 15 May 2007, Air India refreshed its livery, making the Rajasthani arches along the windows slightly smaller, extending a stylised line from the tail of the aircraft to the nose and painting the underbelly red. The new logo features on the tail and the engine covers with red and orange lines running parallel to each other from the front door to the rear door.
