I recently left on Friday the 25th to Miami. I went with Aerolineas because they were the most stable airlines I could count on since I had to take a taxi from Tucumán (frequent back and forth flights from BA to Miami) without them unexpectedly canceling the flights, like American.
Since Latam stopped flying in Argentina, I received an email on July 15 saying my ticket would be refunded for my original flight from Tucumán to BA. I have still yet to receive any refund.
This was my experience, take it with a grain of salt.
Best of luck.
