Soooooo...there's 1 lounge, as best as I can tell.
It's a "copa club" but really nothing suggests that other than the sign. It's for Copa, AV, AC and about 15 other airlines lol. There's a section for "mastercard black" but I got the feeling maybe that was a Latin America only card, it didn't look like anything I'd seen before.
It's a decent sized room that opened around 5 maybe earlier. They have breakfast for purchase, or some free snack type items. They gave me 1 drink ticket, which I guess is for booze, but it was 5am and that's early even for me. Not sure what the scoop is at night. That's pretty lame if they only give you one drink, since both other Copa Clubs I've been to have no limit. Wifi was fine, and there's a 2 computer business center. It's at the far end of the terminal though, which could be great or bad for you. As it turns out my flight was at the complete opposite end of the airport.
