Most international flights arrive at the Ezeiza International Airport (Ministro Pistarini), while domestic flights arrive at Aeroparque (Jorge Newbery).
Currency can be exchanged in the airport at Banco Nación. Teller machines are available and work with most major credit cards. Public phones are either coin or card-operated. Cards are available at the airport. You can also dial #19 to make a collect call.
A bus company (Manuel Tienda Leon - http://www.tiendaleon.com.ar) offers transportation to downtown Buenos Aires at $22 (argentine pesos). The ride takes about 40 minutes. At the bus first stop in Buenos Aires, mini-vans redistribute passengers at no extra cost within an extended area (always near downtown). The ticket stand of the Manuel Tienda Leon company is the first stand after you exit customs.
A taxi ride from the international airport into downtown Buenos Aires costs approximately $50 (argentine pesos). We recommend that you use official taxis only.
There is also a public transportation bus that serves downtown Buenos Aires at a cheaper rate, but we do not recommend it if you carry a significant amount of luggage. If you do take this bus we recommend the differential service (signaled by a D behind the windshield).
Facultad de Ciencias Exactas y Naturales - Universidad de Buenos Aires
The University Campus (Ciudad Universitaria) is served by the bus lines 28, 33, 37, 42, 45, 107, 160. Some buses end their route before reaching the University campus. Only those with a special sign "Ciudad Universitaria" behind the windshield serve the School site. You should step down from the bus at the first stop inside campus. All bus routes end at their third stop inside campus. The bus fare (80 cents) must be paid aboard, using coin-operated ticket machines. You do not need to pay the exact fare, but you must pay with coins (the driver will not provide change).
Card operated public phones, for local and international calls, are available in the ground floor of the building. Cards are available in the kiosk next to the building entrance. Long-distance phone and fax services are also available in cabins next to the entrance to the second building (Pabellon 2). The rates for international calls from these cabins ("Locutorios", also common downtown) are cheaper than hotel phone rates.
