Lovely to hear from you Kruz. I applied to p&o as normal. I received the confirmation email on 2nd Feb. It was the 7th. before they redirected me to stockperks. It then took until 13th for stockperks to verify. So I suppose you could start the process. Regarding p&o admin I received 6 notifications of receipt of claim.,...2 after they had redirected me to stockperks!
Good luck, and enjoy your cruise
