NMHHHH 😔
I fear the worst for you NMHHHH, especially after such a long hold. Ultimately they have retained you, which doesn't make this a fair system. It never is.
I went through the same NMHHHH with the last change in 2005. My era should have received "Flying Pay" at the 72 week point in accordance with the agreed position on joining the RAF.
I didn't really chase at the time, because I'd only just joined.
Should have had flying pay in 2005, but didn't receive it until 2008 and lost out (c. £20,000 plus). The new proposal is "allegedly" much more of a hit initially for those who haven't finished their Phase 2 trg.
We need the details sooner rather than later, especially those like yourself who may be significantly impacted (supposedly).
Good luck.
I'll keep chasing and upload any links to updates if and when they are released.
