Has anyone done this routing in Biz?

I know it's like a domestic configured 737 on CO. I think it's a great deal since, as a CO Elite, I got an upgrade at booking from paid Y ($1200 RT).

Anyone have any experience with the Business Class service on these routes? (JFK-PTY leaves at 5am; PTY-EZE leaves at 11:05am; EZE-PTY leaves at 1PM; PTY-JFK leaves at 7:30pm.)

Also, does Copa have a lounge/contract lounge at JFK for Biz Class pax?

Thanks!
