Copa is a bit better than Domestic F now, with recliners that have decent legroom. More like a PremY product.
Avianca on the twin-aisle planes will be a real J cabin. But on the narrow-body will be domestic F(ish).
Basically a question of whether you want mediocre for both segments or a good/worse split. Also, flight times, redeye or not, ease of connection, etc.
