Copa is certainly not my dream job but I am here making the best of it...for now. If you are truly needing a direct entry Captain job and you want 737NG PIC then it is alright.
Pay is low, you'll clear (after taxes) about $4000.00/month while in training ( approx 6-8 months). Then the pay increases to about $7500/month take home.
Days off are especially bad here. I am averaging about 10 a month but the guarantee is only 7.
Commuting to the US (Copa jumpseat) is easy, but you'll need time off to do it.
The flying is a lot of red-eyes coming back from Brazil, Argentina, Chile, etc and a lot of CDO's. Crews are like Zombies here for the most part. Fatigue is a BIG issue here.
Good Luck with your search.
