No Floor Prices on Domestic Airfares/ Advance Bookings

And what is the cost of transportation to El Palomar Airport from CABA?
From my part of CABA at the moment it is $6.75 with SUBE, $3.04 with SUBE Social and $20.00 cash.
From Retiro, $8.25, $3.71 and $20.00 respectively - but see my comments below.

The plan is that when the improvements have been finished the Linea San Martin will run frequent electric services from Retiro to El Palomar station which is just a couple of hundred metres from the main entrance to the airport. At the moment, as you well know, the infrastructure improvements on the LSM are making any travel a headache but it should get better eventually and your low cost flight can be preceded by a low cost train ride to the airport.

I'm the bloke who fed El Palomar's details to so now you can watch graphics of planes taking off and landing there and view the arrivals and departures and other data.
