Lots of rumours and unconfirmed reports... but still nothing tangible - other than flight loads of what has been approved by the ANAC are at all time record highs. Average Economy fares (for departures in October) for a EZE to US & return ticket are north of $3500. Average Business fares are more than $6000.

To put this in perspective, under "normal" operations it is possible to get discounted Business class fares I (India) for between $2200-2300

As is to be expected, prices plummet starting November 1st. Lots of people are desperate to get vaccinated before the new US entry requirements go into effect.
