You will just have to pay the difference between the economy price you paid and current F price. I would recommend looking up the current F price and know how much you paid (or in this case the company paid) as I have had an agent misquote me at first but I think it was a new agent and she was able to fix it when I told her the F price on the website. The confirmation code and such will remain the same.
