American Express is back with another great Amex Offer. This time, targeted cardholders can receive significant cash back on purchases with Argentinian airline, Aerolineas Argentinas.

Some Amex cardholders are seeing the targeted offer in their accounts for $100 back after spending $500 with the airline (in one or more transactions). Cardholders have reported seeing it on The Platinum Card® from American Express and The Business Platinum® Card from American Express, though it could also be available on additional Amex cards.

That $100 off translates to a 20% discount if you’re purchasing a $500 fare. When you add in the minimum of 2,500 Amex points you’d earn if you purchase with the Platinum Card (since it earns 5x points on airfare booked directly with the airline), you’ll net $48 worth of points according to TPG’s latest valuations.

Aerolineas is a member of the SkyTeam Alliance and is Argentina’s flag carrier. The airline flies nonstop from Buenos Aires (EZE) to New York (JFK) and Miami (MIA), in addition to loads of South American destinations.

Since Aerolineas is a Delta partner, you can earn SkyMiles and elite credits with the airline. The earnings aren’t amazing for economy, but they’re based on distance flown instead of dollars spent, which can rack up pretty quickly for flights between North America and Argentina.

If you do plan on taking advantage of the deal, you’ll want to add it to your card first. To see if you’re targeted, log in to your American Express account and scroll down to the bottom of the home page, which is where you’ll find if you’ve been targeted for the offer. If so, click “Add to Card” and you should be good to go.

The offer expires on September 27, so make sure to complete your purchase before then. Also, you’ll have to complete your purchase through the US version of the website: aerolineas.com.ar/en-us.
