Does anyone know the best way to procure opera tickets for the Buenos Aires Teatro Colon? Need to purchase from U.S. for early spring travel.
Buy them on the Teatro Colon website

If it is still available, consider a backstage tour during the day. Interesting old place, recently emerging from a years-long rehabilitation.
