As per the Copa Airlines name correction policy, the name on the ticket must be exactly the same as it appears on the government issued photo ID. So you see a discrepancy in your name, call the airline customer service. You may be asked to submit a copy of your legal travel documents to complete the request.  The airline will correct the name on the PNT. If that's not possible, you will be issued a new booking reference for the same travel itinerary.
