Flights to EZE/SCL in J for btw 1.1-1.5k

[Drago]

Seems like it's lie flat, flying on AM, up to 200% mileage accrual on DL

Also, some CC's have a 2-4-1 deal.
"Don't forget about the World Elite MC benefit they have... 2-4-1 on AM J fares. I got off the phone with one of their travel advisors and they quoted me ~$2,200 in total for two after the 2-4-1 and the taxes/fees on the companion ticket. $1,110 per person is pretty darn good if you ask me."
