I frequently use Copa and have to say that the planes are clean and that they have very on-time departure and arrival times. A big issue with them is the customer experience from a support perspective. I left my carry on by accident on the place and there is no way to access customer service to be able to know the location. They have a very outdated form on their website to submit these types of claims but it is a far cry from even the ones used by US Airlines which we know are not the paragon of customer service. At this point I need my carry on, especially because I have very important medications there and they provide no number to assist.
