AF Form 988, Leave Request/Authorization - also known as the AF Leave Form and the AF IMT 988 - is an Air Force (AF) form used to request and authorize a leave from service. The latest version of the form was released by the Air Force (AF) in January 2010 with all previous editions obsolete. An up-to-date fillable AF Form 988 is available for digital filing and download below or can be found through the Air Force E-Publishing website.
The AF Form 988 can also be supplied through the chain of command. Before departure, the AF member is required to have the AF leave authorization approved and enough funds for expenses, including costs for travel, in case it is not possible to return on time by military air transportation. If the AF member needs to request an extension of leave, they must obtain approval from the right individual.
