You will need to create a new seating configuration for these seats as you cannot use existing ones on new aircraft. You do not get charged for changing existing aircraft to use this new configuration.

II use Lie FLat 140 and cannot use those configs anymore as well?
As written in another thread - due to the lie-flat 160 adjustement and the changed floorplan for the widebodies we made another cabin generation like the last change too. Therefor you can not use the last configurations but you will receive the money back on changing the configurations, As the former configuration can be used on already assigned aircraft, there is no need to change them if you don't want to.
