You’re flying into the Southern Hemisphere, so reverse your seasonal thinking. If it’s winter in New York, it’s balmy summer in Buenos Aires. Pack layers for the flight—a cashmere sweater for the cabin and a linen shirt for when you land—because Buenos Aires weather is famously fickle.
Pro tip: bring an empty mate gourd in your carry-on. You’ll see locals sipping this herbal tea everywhere, from subway cars to office desks. It’s a cultural baptism you can join in on within hours of landing. Just don’t forget the bombilla (metal straw).
Fun Fact: The Dakar of Flights
Did you know that the route between New York and Buenos Aires is one of the longest over-water flight paths from the U.S. that isn't transatlantic? You’ll be flying mostly over the Atlantic before cutting into Brazil. Look out for the Amazon delta in good weather—it looks like a sprawling green tapestry.
