The Copa Club is the only airline lounge in PTY and it can get very crowded during peak times and used by AF/KL. I feel that the facilities, especially showers and WC's are not sufficient for the amount of traffic that the lounge receives. Catering is very poor for a hub lounge and it reminds me of an ex-CO lounge from the 1990's.
I had a good flight with attentive crew, but the catering is odd to say the least. There should be either a hearty breakfast or lunch after dept. I assume that most passengers would be hungry at 09:16 and to be served a snack plate at the beginning of the flight is disappointing. During the lunch service I noticed that there was no soup nor a second choice for dessert (ice cream sundae) which are offered during dinner. Apart from these the main dishes are exactly the same.
After taking 6 flights on CM I feel that this is good airline with plenty of room for improvement. Its on time performance and ease to connect at PTY are major advantages. As an elite frequent flyer my upgrade success has been 5 out of 6 flights which is pretty good. Crew for the most part are professional and courteous. If you are flying Y, catering is very generous and meals are fine. The food in J can range from OK to downright inedible.
