Arg's and moreso Venz's currency controls and high inflation (not hyper- yet in Arg, I believe Venz is now technically hyper-/VRI) render selling tickets domestically pretty much worthless: 21st century airlines aren't setup to recognise revenue at black market/"unofficial" exchange rates and to sweep domestic currency to dollars daily at these rates.
That doesn't mean that people outside the country don't want to pay good money to fly there (I now basically need to fly private to get to CCS), so I wonder why airlines don't just stop selling tickets in those locations while flying there. Wealthy locals will 'get the joke' and start booking their roundtrips ex-MVD or MIA-EZE-MIA
