Ok. I have to add two friends. Only makes sense if you travel very little on oneworld but still want Sapphire status or you want AA miles.
Brazil AA 5 miles per dollar spent
El Salvador 2 miles per dollar spent
You need 75k miles for Sapphire (AA: Platinum, BA: Silver and Gold otherwise) and 125k for Emerald (AA: Platinum Pro wtf, BA: Gold and Platinum otherwise).
When 5x miles, you silly only have to spend 15k for Sapphire but will list on bank fees etc. But could still be worth it if you want to get a residency there.
