So flew BA on 30th Jan (Friday), was expecting it to credit yesterday (Wednesday) as per various reports and was dreading having to go through a manual claim again, however it successfully credited this afternoon (Thursday). I really don’t understand these erratic patterns of crediting but I’m happy it credited automatically nonetheless.

Also I decided to take the plunge and upgraded via a POUG, it successfully credited as “I” class (even though BA POUGs actually change the ticket to “U” class) including the uplifted 25% extra status bonus for BA marketed tickets as Platinum! Really good to know BA POUGs earn the higher amount towards AY+ also.
However I suspect if it didn’t credit automatically, AY+ may then just credit it as the originally booked fare class!
