I paid for my one-way flight to Buenos Aires using credit-card points.Anny Caba I spent a year saving up credit-card points, then used 33,000 miles (plus $5) to move to Argentina. For the next seven months, I continued to rack up points for smaller trips around South America. The points allowed me to save money long-term and explore more deeply than a regular vacation. The idea to move from New Jersey to Buenos Aires came to me one afternoon while watching the Diego Maradona (famed Argentine soccer player) biopic series on Amazon Prime.
