I recently heard Air Panama actually makes you sign a training bond with them since many people just use them as a trampoline to jump into Copa. On regards of fly trip I really don't know. A friend of mine (Panamanian) just got hired there so they may be hiring. Also, this is just a rumor but I heard that Copa is currently hiring mostly pilots from South America (Argentina, Brazil, etc.) from airlines which are almost extinct, but since they already have jet experience, the transition to fly for them is quite easy. Again, this is just a rumor and can't really confirm but kinda makes sense.
