In Argentina, people become legally adult at age 21. Minors traveling alone or accompanied by an adult other than their legal guardian must get a written authorization, approved by the Argentine Consulate in the country of residence. We recommend not using non-authorized taxis or transfer services, which are offered, even if they are cheaper, as they can be unsafe. Not many shops offer this advantage outside Buenos Aires, but the Government is working on expanding this benefit nationwide. There is an office for VAT reimbursement at the Ezeiza Airport.
Domestic flights are expensive, although the entrance of new airlines is fostering competition.
You can get better rates if you purchase tickets well in advance. The frequency and availability of flights to main destinations is good. They are valid for 60 days and must be purchased in the country of origin. Buses are a common mean of transportation since in general, they offer a good service at a very reasonable price. There are older and less comfortable vehicles for regional and local distances within the provinces.
