That's better than buying the United codeshare, because United will book the Copa leg into "Z" and then they will try to tell you that a "Z" on Copa is not mileage eligible even though it's not really "Z," it's a Copa "D," and mileage eligibility is supposed to be determined based on the metal, not the carrier selling the codeshare, but don't even get me started on this . . . .
