Retiro Bus Terminal: +54 11 4310-0700
The Retiro bus terminal is large and hidden behind Retiro train and Subte stations. For long distance buses it is advisable to buy a ticket several days in advance of your trip. Be sure to arrive about 45 minutes before your departure and always ask at an information counter if your gate number is the same as the one printed on your ticket. You will be given a range of possible gate numbers for example 17-27. Watch your belongings carefully at Retiro as it is often crowded and there have been reports of thefts and even muggings at night.
Aerolíneas Argentinas and LAN Chile offer connections between Buenos Aires' international airport Ezeiza and many cities throughout South America, as well as North America, Europe, Australia and New Zealand. Qantas no longer offers direct flights from Sydney to Buenos Aires, instead flying to Santiago - home of it's OneWorld Partner LAN, where travellers can connect onto multiple destinations in Argentina.
There are international flights to other airports, such as to Mendoza with LAN from Santiago Chile and TACA from Lima Peru. If you fly into Argentina to an Argentine airport other than the two in Buenos Aires, you avoid paying the Reciprocity Fee see above payable by passport holders of the USA, Canada and Australia and if you book your bags through Santiago to Mendoza you also avoid the similarly hefty Chilean reciprocity fee as well.
If you plan on visiting Buenos Aires you will fly into Ministro Pistarini International Airport IATA: EZE; if you're travelling to another location in Argentina you may have to travel from Ezeiza to the Aeroparque Jorge Newbery IATA: AEP, the domestic airport in Buenos Aires. One problem is that the airports are located on opposite sides of the city, so some time has to be factored when travelling from one airport to the other. There are cheap shuttle buses which take you there in about an hour, but travel time varies greatly depending on traffic. There are few flights mostly to Río Gallegos and Ushuaia, which leave early in the morning from Ezeiza International Airport. All the other domestic flights and also to Uruguay and Paraguay leaves from Aeroparque Jorge Newbery. Be sure you are in the right airport!
You should be able to ride a motorcoach or hire a service taxi from one of the booths after you clear customs. The fixed rate for a taxi from Ezeiza international airport to Buenos Aires is ARS250, the rate from the Jorge Newbery domestic airport to town is ARS100. Dec 2013
Ezeiza International Airport EZE: +54 11 5480-6111
If visiting another city there are a number of airports throughout the country. Many find it far easier to travel to a neighbouring country and then take a short distance hop to the smaller airport. All major cities in Argentina and major tourist destinations like Mendoza, Perito Moreno and Iguazu Falls have airports nearby. There are several national airlines, with different levels of service. In general flying gets you everywhere quickly and cheaply relatively. Although the buses in Argentina are amongst the most comfortable in the world and are reasonably priced, travelling takes a lot of time because of the distances and slow road travel involved.
Passengers leaving Ezeiza Airport NO LONGER have to pay the "departure tax" of USD29 USD8 to Uruguay and domestic flights after check-in , as they are now included in the prices of the tickets.
Regular catamarans routes link Buenos Aires with Montevideo and Colonia in Uruguay. The company Buquebus (http://www.buquebus.com) has both a slow 3 hours and rapid 1 hour ferry service that departs several times a day to Colonia. Ferries depart from the downtown Buenos Aires neighborhood Puerto Madero. There are two companies Cacciola (http://www.cacciolaviajes.com and Líneas Delta (http://www.lineasdelta.com.ar)) that link the city of Tigre with Carmelo and Nueva Palmira in Uruguay, respectively. Trains (http://www.tbanet.com.ar) to Tigre depart from Retiro one of Buenos Aires' main train stations every ten minutes. The trip costs ARS1.1 and takes 50 minutes.
To a lesser extent, Grimaldi Freighters (http://www.grimaldi-freig...) run freighters which carry up to 12 passengers from Hamburg, London, Antwerp, Le Havre, and Bilbao to Buenos Aires every 9 days. They also carry cars and you drive your car on and off - unlike other freighter services. More information can be found on the website.
