I'm currently a US GP, and planning significant travel on UA this year. I'm thinking it would probably be more valuable for me to be a US Premier Executive than a US GP because:
- I can earn upgrades on UA
- I can take advantage of UA mileage bonuses
- Have a gut feeling that miles earned in MP program are safer than DM miles

That said, I know UA policy is NOT to comp status based on another *A carrier. My thought is that I could probably do a backdoor comp by getting CO to comp my US status, and then taking that CO status to UA for a comp.

Am I being silly? I'd appreciate advice and recommendations. I realize that getting a status match is a one-time event, so it feels a bit extreme to do that TWICE in one year. I've already earned 7500 status miles on US this year, so I need to decide now if I'll proceed with US or make the switch before I've lost the opportunity to earn the 50K I'll need to maintain the status.
