What i think would be reasonable (especially as an top tier frequent flyer in their programme), would be to receive an Y to C upgrade voucher for one segment for another fight. " Sorry we had to downgrade you, we will make it up by offering you an C seat when flying y (if available). That is next to the 75% rebate on the 1 segment.
Otherwise airlines can make good money by letting customers pay for an expensive business class ticket, en then downgrading them to economy. ^
