American Airlines Lie-Flat Business Class to Argentina From 50,000 Points: 7 Dates, Up to 5 Seats!

American Airlines business class from Miami to Buenos Aires, booked with Alaska Atmos Rewards points: 50,000 points one way per person, plus $25.60 in taxes and fees (from Seats.aero). Book through Alaska, not American: AAdvantage may charge a different price for the same seats.

Dates (2027), all nonstop MIA to EZE:
- February 2: AA933, Boeing 777-300ER, 2 seats
- June 29: AA907, Boeing 777-200, 3 seats
- July 3: AA907, 777-200, 3 seats
- July 4: AA907 and AA931, 777-200, 2 seats on each
- July 12: AA907, 777-200, 5 seats (best for groups)
- August 30: AA907, 777-200, 2 seats
- August 31: AA907, 777-200, 2 seats

On July 4 the seats are split across two flights, so four people can't all count on the same plane.

The seat: lie-flat beds in a 1-2-1 layout, so every seat has aisle access, on both the 777-300ER and the 777-200. It's an overnight flight, so that bed matters. American can swap the plane, so check the seat map.

How to book:
1. Go to alaskaair.com, sign in to Atmos Rewards and choose to book with points.
2. Search one way MIA to EZE on one of the dates above.
3. Pick the American Airlines flight in Business (AA933, AA907 or AA931).

Bilt points transfer to Atmos Rewards 1:1; transfers can't be undone. These numbers come from Seats.aero (October 24, 2026) and still need checking on alaskaair.com.
