I have expressed in other threads that my primary concern with the announced changes is the loss of CPU and RPU availability from northern South America. In particular, I was perplexed by the fact that Copa flights SJO-PTY-MCO/MIA were eligible, but Copa flights MDE-PTY-MCO/MIA were not. It's the same distance. Under the rules as presented to us, even the short flights between northern South America and Central America will not be eligible for CPU or RPU. That is the literal interpretation when one considers that the Panama-Colombia border is the dividing line between the North and South Americas. This morning I wrote to the CEO of Copa to get this confirmed. Pedro Heilbron is like the anti-Smisek. I got a personal reply today. He did not have the answers, but promised to have someone who does know get back with me promptly. Literally 10 minutes later, I received a reply from Copa's Director of Loyalty Programs. I'm very pleased to report that he assured me that the changes UA has made to the MileagePlus program do not affect Copa Airlines. The most striking statement from his email is, "If you are a Premier MileagePlus member flying on any Copa operated flight you will be eligible for a CPU." So on Copa Airlines, northern South America to anywhere they fly in the USA is still CPU eligible. RPUs are also available, but only by phoning UA's MileagePlus desk. That could prove to be interesting! I really enjoy flying on Copa. One of the reasons is their CPU availability for 1Ks. I was just concerned about flying into FL, but this means UGs for everywhere they fly. So UA will still get my domestic USA business, but from now on I'll be flying CM to get to my gateway city. This clarification email came late in the day, so I did not receive a reply to my request to copy and paste the contents. If he gives me the approval, I'll be happy to share it here promptly.
