Singapore Airlines Ltd said on Thursday it was in confidential discussions with India's Tata Group regarding a potential deal which may involve the integration of Vistara and Air India.
"The discussions seek to deepen the existing partnership between SIA and Tata, and may include a potential integration of Vistara and Air India," Singapore Airlines said in a statement.
However, it added the discussions were ongoing and no definitive terms were agreed upon yet.
Singapore Airlines owns a 49 per cent stake in Tata SIA Airlines, which operates Vistara, while the remaining 51 per cent is owned by the Indian conglomerate.
Air India did not immediately respond to a Reuters request for comment.
