Subway fares for all six lines in Buenos Aires City rose again on Friday to AR$574 (US$0.63 at the official rate, US$0.53 at the MEP rate), a 359% increase from the previous AR$125 ticket price for one ride. 

Fares are set to rise again in the coming months, to AR$667 in June and then to AR$757 in August. 

The premetro, a light rail line on the outskirts of Buenos Aires that connects with subway line E, also rose to AR$201. It is set to go up to AR$233.45 in June and AR$265 in August. 

The hike in fare prices was temporarily put on hold this week after Leftist Front national deputy Myriam Bregman filed an injunction asking a court to halt the raise. Judge Elena Liberatori granted the request, saying that subway-operator SBASE needed to present all pertinent documentation that justified why the raise was necessary. 

The judge received the information on Thursday and lifted the injunction, allowing SBASE to move forward with the raises. 

As with buses and trains, subway users who do not have a registered SUBE card pay higher fares. In the case of subway tickets, one ride in August will cost AR$859. Pemetero trips will be AR$301 per ride. You can find out how to register your SUBE card here. 

Passengers automatically receive monthly discounts that progress with the number of trips they take. These are 20% after 20 trips, 30% after 30 trips, and 40% after 40 trips. Pensioners, students, and welfare recipients will keep their fare discounts. 

According to the government, the increase reflects a rise in operating costs. Subway fares have already risen twice in 2024, from AR$80 to AR$110 in January, then to AR$125 in February.
