I will be traveling to Hawaii on American in November. I made the reservations about 6 months ago becuase it fills up quickly. Unfortunately at the time I did not have enough miles for 1st class.

Is there any chance of getting a complimentary upgrade? I know there is no chance but just wondering if anyone had any luck.

I now have enough miles for 1st class but I will have to pay all sorts of fees to change now. Anyone know a way around these charges?
