I am trying to understand how PPS Value is calculated. In the past 12 months I took three return trips from Australia to Europe. Twice in Business, once mixed class Business/First. All of the trips credited miles to my Krisflyer account but I only have 5630 PPS value listed in my account summary on the website. The total cost of those tris added to about AUD26500 so I am a bit confused trying to understand where all the money went. I know they don't include taxes - unfortunately SQ never gave me an itemised receipt for my mixed F/J trip so I don't know exactly how much was taxes for that journey, and I wonder if they arbitrarily decided to exclude the money I paid in travel credits towards that journey (not really fair since it was my cash that I kindly let them keep for 18 months). But even so I would expect to be closer to 20000.

The account summary online does also say "Required: 19,370 PPS Value by 31 Aug 20", which was over two years ago, so I think there must be a bug in the web page, but although I've emailed twice asking about it I never got a response. Just wondering if anyone else had a better insight into what money they count towards PPS value and any weird and not-obvious exclusions they might apply.
