We flew from SFO to Atlanta, change plane and flew to Chili, then Buenos Aires. The whole trip took over 30 hours, but we did hang out at all airport lounges from our credit card for food and shower. The eSim works great, iPhone was online and we booked an Uber and on our way to hotel within 10 minutes. Before the trip, I learnt the exchange rate was 360 peso to $ 1 USD, so I gave a huge tips (50%) to the driver knowing how little the average worker made. Later did I know that the inflation took a dive in after market, as I got 920 peso instead from street money exchanger.
