Mumbai: Tata-Singapore Airlines joint venture airline Vistara will launch its operations today with its first flight from Delhi to Mumbai, ushering in a heightened competition in the domestic aviation market.

The launch of the new full-service airline will also mark the re-entry of the Tata Group in the airline business after over six decades. The group holds 30 per cent stake in the domestic arm of the Malaysian budget airline AirAsia India.

Vistara will be the third full-service carrier in the country, after state-run Air India and private carrier Jet Airways.

The Tata Group had announced in September last year the formation of a 51:49 joint venture with Singapore Airlines to launch a full-service carrier in the country.

The two JV partners had made attempts to enter the domestic skies earlier too, but in vain.

The airline had applied to the Directorate General of Civil Aviation (DGCA) for the flying permit in April last year but could get it only late last year, after a delay of almost nine months.

On December 18 last, Vistara had announced the launch of its operations from January 9 with flight from Delhi to Mumbai and Ahmedabad.

Vistara, which has two leased A320s as of now, will operate 148-seater Airbus A320-200 with 16 seats in business class, 36 in premium economy and 96 in economy on these routes.

The airline will operate flights from its Delhi base to Goa, Mumbai, Bengaluru, Ahmedabad, Hyderabad, Chandigarh, Srinagar, Jammu and Patna in the first year, the airline had stated in the plan, submitted to DGCA at the time of applying for air operator permit.

It plans to operate 87 flights in the first year, with five leased Airbus A-320s, and then scale it up to 301 flights by the fourth year with a fleet of A320s.
