We will see when the Ad appears, bear in mind though that each new aircraft purchased "normally" includes a certain number of TR's per airframe, so "maybe" not.
It appears the operation is quite probably being set up under a different company name/AOC. This, & the requirement to have 500hr widebody time for Capt, (claimed as needed to reduce line training time due previous long-haul experience) is "possibly" a way to avoid having to take, in seniority order, those that would insist most to keep their permanent Norwegian contract. Existing Norwegian pilots can apply, but must take a leave of absence from their permanent contracts to fulfil the 3 years here.
I pass no comment on any of this, merely reporting how it is being executed.
