Airman Basic through Airman First Class
Promotion timing can depend on entry grade, enlistment program, time in service, training, commander recommendation, and official personnel records.
Airman First Class to Senior Airman
The normal Senior Airman date uses the governing time-in-service and time-in-grade paths. BTZ is the competitive opportunity to promote six months before that normal date.
Estimate the final portion of the timeline with the USAF BTZ Calculator.
Why individual records differ
Advanced enlistment grade, academy or ROTC status, prior service, breaks in service, demotions, corrections, and component-specific rules can change the timeline.
