Lounge help PTY.
 

Hi all, I have an 8 hour layover at PTY. Can someone clear up how many lounges there are and which is better? I have Priority Pass and a Lounge Buddy credit from my cc. I am fying Copa in Business class. Thanks for any information...

CM has two lounge, one at each terminal. Lounge at T2 is newer, bigger and nicer. Neither have much amenities, but are good enough to spend some time in (Not 8 hours though). You can walk from one terminal to another without any problems.

There are two other Priority Pass lounges at PTY. One is landside and the other airside. You are better off at the CM lounges.

As a business class passenger, you will be able to enter the Copa Lounge. I would recommend the one in terminal 2 as it is newer and bigger. I recently spent my time there during my 7 hour delay in Panama. I was about to go to Panama City or even visit the Panama Canal, but I was too tired, so I ended napping in the enclosed section for Presidential/Platinum members, which BTW is not all that.

For a 8hr layover I would go to Casco Viejo or Multiplaza and have a nice meal, Or even visit the canal (Miraflores locks) you'll have plenty of time.
Uber is cheap and realiable.

Is there a place to store my carry-ons if i go into Panama?

In the arrivals hall of Terminal 1 there's a luggage storage place, I'm quite sure there isn't one at T2 but it's short hop with the shuttle bus.
