Well, re. the CUN question (although technically CUN is not related to the topic title)....

If you're traveling on an award, I wouldn't say F service into CUN is that fantastic as to warrant extra transit/connection time that cuts into beach time. So, I would opt for the Alaska nonstop. Since it's an award, you won't earn miles, so there's not that incentive to take a longer routing. You'll likely find better award availability on Alaska, anyways. The CO and NW F service to Mexico will be on par with domestic coach F, but with a little better food.

If you're paying for the ticket, then from a pure mileage standpoint, the MSP-MEM routing will net about as many miles as a single MSP connection, and slightly less than a DTW connection- depending on when you travel, seasonal flights may be available. You would earn the most miles on the CO EWR connection. But you know that.....

So, mileage considered, and assuming the Elite upgrade will be much more secure on NW than on CO, you may consider it a matter of if the 500 mile difference for DTW vs. EWR travel is worth the better chances of upgrading. Alaska wouldn't allow NW/CO elite upgrades at all. If I were you, I would go for a single NW connection via DTW and elite upgrade.

I hope you find an answer to your question somewhere in the above post.....
