Well I called the DM Center and asked if I could do this...

I can see at least two F class seats open at 25K. She tried to upgrade it for 10K like it was a paid ticket and told me there was no availability. I then explained the award situation and asked if I could change to an F saver for an extra 12.5K, but that was also a no-go.

Should I give up or does anyone think I'll have any luck on this?

I should have booked it in F to start, but I don't feel like I'm asking for too much....
