Both are fine but Copa has much better customer service. We fly to and through Panama City regularly. It’s similar to a United or AA in that the food and service are fine but every few flights you get a grouchy crew. It’s not amazing service like the Asian airlines, but it’s def a step above Avianca which feels more budget in that they nickel and dime you for everything.

Avianca only if its Central America, Copa if its South America.
