I’m here now, in the middle of DAV-PTY-IAH-DFW (pretty long day after starting in Boquete!).
The lounge itself is pretty nicely updated, very spacious and not too busy atm. Maybe 2/3rds full. As for the food, it’s on par with what others have posted. 2 different pastas, both cold tho I think only one is supposed to be. Rice, some veg medley that didn’t appeal to me at all, and a carrot dip with stale bread to accompany it.
I’m considering retiring in Panama, so I might eventually be transiting PTY fairly regularly. When I do, I’ll make sure I’ve eaten before I hit the lounge.
