I've been downgraded from J to Y on Trans Tasman in Feb 23 due to being changed to A320 Neo. Called up and explained the situation, another flight goes 2 hours later, wouldn't put me on that flight as the class I booked in "J" isn't available. Asked to talk to supervisor unwilling to assist. Airnz use to be good to deal with it's now gone to the pack! QF here I come with a status match!
