Early years:

Air India was founded by J. R. D. Tata in July 1932 as Tata Airlines, a division of Tata Sons Ltd. (now Tata Group). On 15 October 1932, J. R. D. Tata flew a single-engined De Havilland Puss Moth carrying air mail (postal mail of Imperial Airways) from Karachi's Drigh Road Aerodrome to Bombay's Juhu Airstrip via Ahmedabad. The aircraft continued to Madras via Bellary piloted by former Royal Air Force pilot Nevill Vintcent.

Following the end of World War II, regular commercial service was restored in India and Tata Airlines became a public limited company on 29 July 1946 under the name Air India. In 1948, after the Independence of India, 49% of the airline was acquired by the Government of India, with an option to purchase an additional 2%. In return, the airline was granted status to operate international services from India as the designated flag carrier under the name Air India International. On 8 June 1948, a Lockheed Constellation L-749A named Malabar Princess (registered VT-CQP) took off from Bombay bound for London via Cairo and Geneva. This marked the airline's first long-haul international flight, soon followed by service in 1950 to Nairobi via Aden.

On 1 August 1953, the Government of India exercised its option to purchase a majority stake in the carrier and Air India International Limited was born as one of the fruits of the Air Corporations Act that nationalised the air transportation industry. At the same time all domestic services were transferred to Indian Airlines. In 1954, the airline took delivery of its first L-1049 Super Constellations and inaugurated services to Bangkok, Hong Kong, Tokyo and Singapore.

The Jet Age:

Air India International entered the jet age in 1960 when its first Boeing 707-420, named Gauri Shankar (registered VT-DJJ), was delivered. Jet services to New York City via London were inaugurated that same year on 14 May 1960. On 8 June 1962, the airline's name was officially truncated to Air India. On 11 June 1962, Air India became the world's first all-jet airline.

In 1971, the airline took delivery of its first Boeing 747-200B named Emperor Ashoka (registered VT-EBD). This coincided with the introduction of the 'Palace In The Sky' livery and branding. A feature of this livery is the paintwork around each aircraft window, in the cusped arch style of windows in Indian palaces. In 1986 Air India took delivery of the Airbus A310-300; the airline is the largest operator of this type in passenger service. In 1988, Air India took delivery of two Boeing 747-300Ms in mixed passenger-cargo configuration.
