Air India is in talks to lease around four lakh sq ft of office space at Vatika's office complex in Gurugram, Haryana.
Tata Group has already signed a letter of intent (LoI) for the office space of about two lakh sq ft with the option of doubling the space later.
The airline will shift all offices to this building. Other Tata airlines - Vistara and AirAsia may also shift to the same complex later.
The Vatika project, One on One, on NH-8 is spread across 2.2 million sq ft and is being developed in two phases at an investment of Rs 1,200 crore.
