The proposed sale of Indian national carrier Air India may affect Changi Airport's biggest ground-handling firm Sats.
Sats, which provides airlines with passenger, baggage and cargo services, owns half of Air India Sats (Aisats), a joint venture between the Singapore firm and Air India.
Set up in 2010, Aisats currently operates in five airports in India - Bangalore, New Delhi, Hyderabad, Mangalore and Thiruvananthapuram.
