I have a flight on 7/20, SAN-DTW-MCO (although the entire trip is 8 segments, a multi-city itinerary over 11 days) and when I tried to call and
pay for an upgrade on that flight - they told me that it was a nonrefundable ticket and you couldn't make any changes.

I can understand a schedule change, or moving to an earlier flight, or just canceling the ticket. But I wanted to
pay Northwest
real money for a set of flights that I know aren't sold out in first. That just doesn't make any business sense.
On the other hand, as of tomorrow night I will be Silver Elite so hopefully I'll start getting some upgrades. Anyone know what the chances of an upgrade on SAN-DTW or DTW-MCO is? They're wednesday flights. Everything I've read shows Orlando as a business-light destination (I mean, it makes sense) and the flight arrives at midnight, so I figure I should have a reasonable chance with that one.
