Air India, which the group had taken control of in January after winning the bid to acquire the national carrier for Rs 18,000 crore in October last year, has set up a team.
Vistara has opened the sale for these additional flights, across all channels including its website, mobile app, OTAs (online travel agencies), and other travel agents.
Sources said Vistara's UK622 flight was heading to Mumbai on Friday when it got hit by a bird, which damaged its radome.
Sources say that more than 30 incidents are reported on average every day, which include go-around, missed approaches, diversion, and bird hits. Most of them have no safety implications.
An engine of a Vistara aircraft on way from Bangkok failed after it landed at Delhi airport, while the cabin crew of an IndiGo's Raipur-Indore flight observed smoke in the plane after it landed.
The airline said one of the engines had developed a 'minor' electrical malfunction after the aircraft landed at the Indira Gandhi International Airport on Tuesday.
The pilot, who was the first officer on the flight, landed the aircraft at the Indore airport recently without first getting the requisite training in a simulator, they said.
The airline will also start daily direct service on the Mumbai-Coimbatore route starting May 27 and double the number of daily flights on the Bengaluru-Coimbatore route from June 3.
Air India, which was founded in the 1930s by the Tata Group and nationalised in 1953, is saddled with a debt of $8.5 billion.
Full-service carrier Vistara's bookings and check-in process were disrupted across airports today due to a technical glitch in its passenger service system.
