I Flew my 70yo Parents 11,700 km to Patagonia..Too Far?

I flew my 70-year-old parents with struggling health issues over 11,000 km to Patagonia... The question was, how far could they go? Torres del Paine is one of the most unpredictable places in the world – harsh weather, vast landscapes, and no real margin for error when you are in your 70's. I usually travel solo. This time, I was responsible for more than just myself.
