LATAM has no special flights scheduled. Their flights were all “regular” flights.
As soon as regular order was repealed for September, everything went bye-bye.
As long as the “special flight” regime is in effect, the Aerolineas flights are the most stable by a long margin.
And though some of their planes are crap and it’s all very Argentine, their safety record is perfectly fine.
Put simply, for a third-world country you could do a lot worse.
Per the update I promised, the Aerolineas flight to JFK lifted off half an hour behind schedule, due to arrive on time. As I write this, it is crossing from Paraguay into Bolivia.
There was space on sale right up to the end. From what I hear the plane was pretty full.
Several of my clients on this flight were Argentines with no US papers beyond B1/B2 visas.
To repeat: Argentines are free to fly to/from the US as they please.
