Money makes the world go ’round, as they say. With the arrival of low-cost airlines to Argentina, however, going around the world might cost you much less than it did before. Last month, President Macri approved hundreds of low-cost flight route within Argentina, to neighboring countries, and, more recently, some trans-Atlantic flights have been approved. In a rush of ticket sales, Spanish-British airline merger IAG, among other airlines, opened low-cost ticket sales this morning. Within three hours, tickets from Buenos Aires to Barcelona were sold out through the end of the year.

A few years ago, a standard flight from Buenos Aires to Spain would have cost upwards of AR $10,000, and that would have been a “reasonable” price. Now the same flight via Aerolíneas Argentinas would put you out AR $19,500. On sale this morning were direct flights from Buenos Aires Ezeiza International Airport (EZE) to Barcelona — El Prat Airport (BCN) for a seemingly unbelievable AR $5,400. The only catch is in the amount of luggage you can bring with you.

The secret to many low-cost airlines are the “add-on” costs. Need to check baggage? That costs extra (AR $2,500). Want in flight food and beverages? That will set you back an extra AR $1,200. Even with all the bells and whistles, though, the flight adds to AR $9,100, about ten thousand pesos less than Aerolíneas Argentinas offers.

Given the mere three hours it took to snatch up the tickets that were available, travelers don’t appear to mind the scaled service costs. If you need to get out of town before the next low-cost ticket craze, check out these other low-cost options from Sky Airlines, which connects Buenos Aires to Santiago, Chile (about AR $2,500), as well as Andas, which connects Buenos Aires to Córdoba (AR $1,675), Mendoza (AR $2,096) and Salta (AR $2,496). Keep your eye out for airline newcomer Flyest, too, with flights out of every Buenos Aires resident’s dream spot — Jorge Newbery Airport (AEP).
