Simple answer is you won’t, due to the 2 day time lag between accruing the required miles for the status and actually achieving the status after the system updates.

Also, retroactively claiming miles flown before you achieved the status does not entitle you to receive bonuses as though you already had achieved the status when you flew.
i.e. if you achieve crystal level on July 1st, flights flown before that date will not earn you crystal level bonuses even if retroactively claimed after July 1st.
