I rejoined last year having left some years ago on PA level 32. I was put back on level 32 with my seniority adjusted by the number of years and days that I was out of the Service. Also, despite being at Flt Lt I have 'grandfathers' rights' to continue to climb the PA spine. I was required to join AFPS 15, and will receive as additional pension to supplement my AFPS 05 pension. It is advantageous because my 'career' average for this portion of my service will effectively be a final salary throughout my time as a rejoiner.
