Tata SIA Airlines Limited, operating as Vistara, is an Indian domestic airline based in Gurgaon with its hub at Indira Gandhi International Airport. The carrier, a joint venture between Tata Sons and Singapore Airlines, commenced operations on 9 January 2015 with its inaugural flight between Delhi and Mumbai. The airline had carried more than two million passengers by June 2016[2] and as of May 2017, has a 3.3% share of the domestic carrier market, making it the 6th largest domestic airline.The airline serves twenty-two destinations with a fleet of Airbus A320-200 aircraft. Vistara was the first airline to introduce premium economy seats on domestic routes in India.

The airline was founded in 2013 as a joint venture (JV) between India's conglomerate Tata Sons and Singapore Airlines (SIA).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.[10] 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.[11] 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. India's Foreign Investment Promotion Board approved the JV in October 2013, allowing SIA to take a 49 percent stake in the airline.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.This was part of Tata's second major foray into the aviation sector along with a minority stake in AirAsia India.The company's first venture, Tata Airlines, was established in the 1930s and later became the flag carrier Air India after nationalization
