Mumbai’s Chhatrapati Shivaji International Airport (CSIA) is one of India’s busiest airports and one of the main international gateways to the country.
United and Air India fly directly from the U.S. to Mumbai, however many other airlines also fly to Mumbai. If flying from Europe, Wikitravel suggests flying from London to get better rates.
There are ATM terminals in the international arrival area and many exchange stations near the exit. In order to take a taxi from the airport to your hotel, you will need cash rupees.
