Mumbai's Chhatrapati Shivaji International Airport, about 30km from the city centre, was recently modernised to the tune of US$2 billion. Now handling all international arrivals is the impressive, remodelled international Terminal 2 (T2), which includes India's largest public art program (a skylighted, 3.2km multistorey Art Wall along moving walkways, boasting over 5000 pieces of art from every corner of India).
Domestic flights operate out of both the new T2 and the older Terminal 1B (T1B), also known locally as Santa Cruz Airport, 5km away. An inter-terminal fixed-rate taxi service (₹230 from T1B to T2, ₹245 from T2 to T1B) operates between the terminals. Both terminals have ATMs and foreign-exchange counters, and T2 also houses a luxurious transit hotel.
Air India, Jet Airways and Vistara operate out of T2, while GoAir, IndiGo and SpiceJet operate out of T1B – be sure to check ahead for any changes on the ground. Travel agencies and the airlines' websites are usually best for booking flights.
There are also normally MTDC tourist information booths at both terminals but these had been removed at the time of research due to the airport renovations, with no planned time frame for their return.
Prepaid Taxi Set-fare taxis cost ₹680/820 (non-AC/AC; including one piece of luggage) to Colaba and Fort and ₹400/480 to Bandra. The journey to Colaba takes about an hour at night (via the Sea Link) and 1½ to two hours during the day.
Autorickshaw Although available, they only go as far south as Bandra – walk out of the terminal and follow the signs. Prices are ₹18 per kilometre (a traffic warden should keep them honest).
Train If you arrive during the day (but not during ‘rush hour’ – 6am to 11am) and are not weighed down with luggage, consider the train: take an autorickshaw to Andheri train station and then the Churchgate or CST train (₹10, 45 minutes).
Taxi The trip from South Mumbai to the international airport in an AC taxi should cost from ₹650 to ₹800, plus the ₹60 toll if you take the time-saving Sea Link Bridge. Allow two hours for the trip if you travel between 4pm and 8pm. From Colaba, an UberGo is around ₹385 off-peak.
Taxi There’s a prepaid taxi counter in the arrivals hall. A non-AC/AC taxi costs ₹560/683 to Colaba or Fort and ₹283/340 to Bandra (a bit more at night).
Autorickshaw Alternatively, if it’s not rush hour, catch an autorickshaw (between ₹22 and ₹27) to Vile Parle station, where you can get a train to Churchgate (₹10, 45 minutes).
