I wasn't trying to be snippy in my reply, but for the information of the OP, domestic first class on pretty much any US airline is but a pale shadow of its' former self. 40,000 Dividend Miles would get you an off-peak r/t to Europe, which would be a much better way (IMO) to spend the miles than on a 2+ hour journey in a tired 737 w/no food going down to Disney.
Just my opinion.
