First off, one star is way too high...
Copa Airlines screwed my business class reservation and caused me to miss an important business meeting. I then blew a thousand bucks making new plans and paying for hotel rooms on two continents. They told me they would refund me but that was 4.5 MONTHS AGO. They continue to blow me off, but they did offer me a $50 voucher on my next flight. Yah, right! Stay away from Copa!
