MTH- I think a negotiated upgrade probably fits best. The TO has definitely acknowledged that they have more flexibility to award better seats in response to "win back offers. After you are in the system and they have collected your money they hold all of the leverage. I wish I could take the credit and say that I planned this whole thing out. To be completely honest I did not renew my tickets and later had second thoughts. I sent the TO an email and they advised that I was eligble for a "win back offer" and to call to see what they had available.
