Vistara received its air operator's certificate from the Directorate General of Civil Aviation on 15 December 2014 and started operations on 9 January 2015. The name was taken from the Sanskrit word vistāra, meaning "limitless expanse". The company unveiled its brand identity "Vistara" on 11 August 2014. The company's first venture, Tata Airlines, was established in the 1930s and later became the flag carrier Air India after nationalization. This was part of Tata's second major foray into the aviation sector along with a minority stake in AirAsia India.

The two parent companies initially pledged to invest a combined US$100mn as start-up capital, with Tata Sons owning 51 percent and Singapore Airlines owning the remaining 49 percent. India's Foreign Investment Promotion Board approved the JV in October 2013, allowing SIA to take a 49 percent stake in the airline.

The JV, Tata SIA Airlines Limited (TSAL), was envisaged as a premium full-service carrier to cater to the demands of high-end business travellers in India's civil aviation market dominated by low-cost carriers. With India opening up its airline sector for 49 percent foreign direct investment (FDI) in 2012, Tata and SIA once again decided to float a JV airline company in India.

The two companies had made a bid in the mid-1990s to launch a full-service carrier in India that was unsuccessful, being denied regulatory approval by the Indian government. The airline was founded in 2013 as a joint venture (JV) between India's conglomerate Tata Sons and Singapore Airlines (SIA).
