1. do partner miles stack with elite status?

looking at BA earn chart https://www.alaskaair.com/content/mi...rtners-british

i see business J has a bonus of 250%
i'm MVP, so i also have a 50%

i assumed the latter only applied to AS marketed flights, and that my BA marketed BA operated flight would not give me this bonus.

however, i have a J flight with 6,588 bonus miles on top of 2,196 flown. this bonus is 300%. so it would seem these did indeed stack.

am i understanding it correctly that they did indeed stack? i saw this reddit thread said they do not: https://www.reddit.com/r/AlaskaAirli...world_partner/

per this post on FT it would seem my math is correct and i do indeed accrue the miles though: https://www.flyertalk.com/forum/alas...ewr-sin-j.html

2. how long should it take to get partner credit? i have RJ flights from 1/1/2024 i requested credit for after 14 days, we're sitting at nearly 90 days later and i still don't have it. i have enough miles in my account to be mvp gold - 41,045 - but it is still showing me as mvp/ruby. plus i have spotty credits for other flights. my flight credit is spotty - i recently got credited for some longer flights, while these prior flights were ignored. am i going to get bonused on the flights in correct order for my status recognition - when it actually comes through - or are they just going to credit a bonus not based on time flown but time credited instead? this seems like i can really lose out, like if all the long flights are credited first and i get bonused on short flights that occur after. this can be a pretty significant difference in the amount of bonus miles.
