Thanks everyone for the input and the welcome. I don't have status but was going to use my Amex Plat credit for the change fee. And yes, if I can get us into F then I was going to also change to a slightly later flight to VCE so we have a bit of a longer layover instead of the 1 hr 45 min. we have now. You all have bolstered my confidence so am back to counting down the days till F seat release (hopefully).
