I don't work for Copa... Seems like a descent airline but pay is low.
I lived in Panama for a while and am married to a Panamanian.
I enjoyed the time there but a small house( 3 bedroom and pool) cost 1500/month and to air condition the 3 bedrooms it was 700 one month.
That is with kids so everything was on continuously but my point is it is not cheap anymore. One can live in cheaper areas but then as a gringo you definitely stand out. It is not really that safe in some parts..
If you like cigars and Chicas then Habanos is worth a shot
