Las Vegas to Historic Sanctuary of Machu Picchu

Cusco, the gateway to Machu Picchu, usually costs well over $1,000 from Las Vegas, and Avianca just dropped it to $532, a 51% discount and the best we've tracked on this route. That's a rare price on a full-service airline to one of South America's true bucket-list destinations. Inca Trail season books up fast, so this is a fare worth building a trip around.
