I flew Copa PTY-LIM and LIM-PTY a year ago. And they were excellent!!!

I hafta second what dgolds said, except I think their Clase Exejutiva may even be slightly better than CO domestic FC. The food and service is equal to, or probably superior to CO domestic, although it still can't match BF.

Their fleet is all 737, so if you're looking for a 767 or 777, you're outta luck. However, their 737 fleet is very new....so new that their planes actually had a "new plane smell."

There's no EUA for Copa, but you can get an upgrade at the airport. And there should be no problem there, as Copa has very few Elites. There were only two of us in FC on the LIM-PTY flight.

Copa is a CO clone....they're 49% owned by CO. And only Panama's restriction on foreign ownership of a Panamanian carrier stops them from owning it outright. Their colors are the same, and they share the Panama City PC with CO.

BTW, the joint CO-Copa PC in Panama City is IMHO the best I've been in. Brand new, a great view of the runway, and excellent service. The attendant actually comes by and personally notifies you when your flight is about to board. Try to find that kind of service in any other PC!!!
