The question was:
Does anyone have any tips or experiences with sending luggage in bulk? I am moving from Zurich back to New York so I have about 3 large suitcases that I need to send… ideally I would like to send it to New York and avoid having to deal with this stuff in Santiago. However perhaps it would be cheaper to send to Santiago… I have no idea how it works and if airports hold luggage for you,etc.
