It is however taking away the NW Plat Confirmed Companion upgrade, but I dont think Golds will notice much of a difference (except for the companion minimum fare class rule).
On leisure flights, where one is flying on his own dime and looking for the best fare, that minimum fare class can make a huge difference. And it is leisure travel where one is most likely going to be taking a companion.
