The most expensive ticket in the country is paid in Formosa with a value of $690. In the Interior the ticket is not subsidized but, through the Compensation Fund (now eliminated), the national State transfers money to the provinces.
Without that money, it would be the provinces themselves that would have to subsidize the tickets and in the current context of cost cuts it seems unlikely. The inequity of transportation rates is a recurring issue among governors and mayors in the interior of the country. In fact, 15 days ago mayors of different cities in the Interior had held a meeting to agree on a common agenda and take it to the Secretary of Transportation.
