Greetings -- looking for experiences doing international transfer at SCL. I have a flight booked EZE - SCL arriving early afternoon on LatAm, then SCL - MIA departing about 11pm. I do not have checked luggage.

Will I be allowed to remain in the sterile transit area to avoid going through immigration at SCL? What is required to be allowed into the sterile international transit area at SCL?

My main concern is how I will get my boarding pass. I'm hoping to be able to get it through online checkin with on American, but if not, I don't know what I will do and if I will even be allowed into the international departures area without going through immigration.

Any recent experiences or advice appreciated.
