Letter of Intent (LOI) Program

Letter of Intent (LOI) Guidance

The Letter of Intent (LOI) program helps fund large-scale capacity projects at primary or reliever airports. LOIs state that the FAA intends to obligate AIP discretionary and entitlement funds from future budgetary authority in an amount not greater than the Federal Government’s share of allowable costs for that project. The FAA issues an LOI to state that reimbursement will be made according to a given schedule as funds become available from Congress each year over the term of the LOI.
