LA: EZE-MIA (non-stop) from $1401
 

Nice sale for non-stop service with LATAM for service between Buenos Aires, Argentina to Miami. The fares in this market are usually a few hundred more (Avianca) but this has the benefit of non-stop service but you can also route via Santiago de Chile to collect some additional miles.

Lounge access on onward Economy ticket?
 

I see that the final leg in your example is in Economy. I'm able to pull up Premium economy, FWIW. As I no longer have status with OW, I'm caught wondering if arrival in Santiago on a Business class ticket is sufficient to enter the lounge when the onward leg is not. The LATAM site doesn't explicitly say it is, and BA dragons have been obnoxious in the past. Any experience here?

I believe this books in Z class which earn 20% EQDs. EZE-MIA-EZE should earn around $1,762. Am I missing something?

Nice fare - I have been looking for something out of Brazil or Argentina like this. I need it for mid-June and this has a 50-day advance, but it is a nice fare. Thanks!
