I'm trying to plan a trip to Buenos Aires with a stop in Iguazu (preferably on the same ticket so it's included). I'm fairly flexible on the order, dates are for the last week of November/1st week of December. It seems like United doesn't fly to IGR at all so I would have to fly to IGU but flying IGU to EZE requires a stopover in Brazil, making a 2 hour flight a 6 hour flight. Is there a United partner that flies IGR to EZE or a better way to book? (I'm flying economy and space doesn't seem to be a problem)
