I just tried one a few weeks ago. You've got to hold a reservation (either online or through the phone center), then call Marco Polo to check on upgrade. If available, you then ask them to hold the upgrade. Then go an book the ticket. Then call back to book the upgrade.
If the upgrade is NOT available, then you you cancel the HOLD on the ticket, and start over with a different flight.
Yeah, it's that bad.
This is what I always do, unless only M class or above is available.
