Operator, Mumbai International Airport Limited (MIAL), claims that the decison to change the name from Terminal 1B was taken to help "easy identification of the terminal and ensure hassle-free transit for air travellers".
Currently SpiceJet, Indigo & GoAir operate from Terminal 1.
Previously, Air India and GoAir operated from Terminal 1A, while Jet Airways, SpiceJet and Indigo operated from T1B.
MIAL notes that Air India and Jet Airways shifted their operations to the airport's iconic new Terminal 2 when it opened in the 2014. Vistara also calls T2 its home.
"The shifting of Air India and Jet Airways to Terminal 2 has helped make transit between international and domestic flights convenient for transfer passengers, thereby saving on time," points out MIAL.
The 33.5km metro line from Colaba-Bandra to Mumbai's SEEPZ Special Economic Zone with proposed stations at Sahar Road, domestic airport and Terminal T2 is expected to further enhance connectivity and facilitate quicker and smoother transit from one terminal to another.
