After reading these posts, I became intriqued with the idea of travelling to PTY, but just now checking CO.com on a number of random weekend dates between mid July through late Oct, the cheapest fare I get from EWR is $518 ?? What is considered their 'off season' ? I was looking at Fri or Sat departures with returns on the following Sun or Mon. I realize with so much business travel to the area, the fares would be higher--but I thought that would be during the week.
