The Blended Retirement System opt-in period started Jan. 1 and runs through Dec. 31, 2018. Tools that can help Airmen determine if they qualify to opt-in and whether it is the right choice for their retirement are available on the Air Reserve Personnel Center website. Additional guidance is available from installation Personal Financial Managers/Counselors, free of charge. Reservists can contact their local Airman and Family Readiness Center or sister service equivalent to set up an appointment. Links to other resources are available on the Air Reserve Personnel Center website. For more blended retirement, see this Military.com section and Paycheck Chronicles post.
