Avianca, which is part of the Star Alliance, is putting its business class flights from JFK to Lima, Peru on sale! Flights start at $669 round-trip, after taxes with great availability through December 2018, with many routes including a lie-flat seat.

This is a really incredible deal — last year, Avianca ran a similar promotion, but with business class seats costing around $992.

Last year, I flew Avianca’s business class from Bogotá, Colombia to Santiago, Chile and wrote a review about it. Although it wasn’t my favorite flying experience ever, I’ve heard the U.S. to South America routes have better service and that, coupled with the lie-flat seat, definitely make this a fare worth checking out.

To find this deal, use Google Flights and search for business class flights between JFK and LIM.
