Aside from the lotto factor of having any open business class on such a flight a day prior, why would one opt for a $400 copay (as much as twice the fare difference) when the cost difference between a Tango and Flex fare (mid-October) is $528 - $262/$328 = $266/$200? And depending upon one's status, confirm the upgrade many days sooner.
Not to knock this advance. It is nice to have the possibility of upgrading from an award or Tango ticket, but the cost:benefit seems questionable. But then it's similar to AC's weird fares when a Latitude can cost $1,200 while business can be had for $700 on the same flight/route (albeit with restrictions).
