Hi, yes it is a bit of a coincidence!! The family come from Puerto Madeira and Palermo etc, but mainly settled in City Bell and Villa Lisa due to the Portuguese connection, so they consider themselves "Portenos"!.
I fly with the Aerolineas guys out of Tolosa when I am there, their charges are way less than $100/hr wet, all published on their web site. I noticed for a long time they matched the blue dollar rate and kept it around $60/hr for the old 172's, But over the last few years the Peso has gone down so much, 2012 6.5 Ars/£, Currently 106 Ars/£!! Also you can get a large boost by sending your money ahead through RIA or any other reputable exchange house. Just to be clear, $100 now is worth Ars 14500
As you can see their pricing now is only Circa 5000Ars/hr for a 172,
