I've been looking at business class fares to/from SCL for the last couple of months, and this is by far the best price I've come across for a departure from anywhere in the U.S. or Canada. The itinerary I booked (June 30) even has lie-flat seats from PTY to SCL. Lots of availability into February 2025.

It won't be Delta One, but it's also about 1/6 the cost. Now to figure out SCL back to North America in mid/late July...
