Q-R5. Did the 2024 Reauthorization make any changes to the Federal Share requirement?

Yes, under certain circumstances. 

For any AIG grant issued to nonhub or nonprimary Sponsors during FYs 2025 or 2026, the Federal Share has changed from 90% to 95%. This change effectively reduces the amount a Sponsor is required to match for a grant. It does not increase the funding provided by FAA.  

Any grant amendments through FYs 2025 and 2026 that increase AIP funding without adding project scope will continue to be subject to the initial 90% federal cost share. If there are any significant changes in project scope or new/amended capitals, then the new federal share will apply as the grant scope is changing. 

For AFR FY 2026, Sponsors can request 95% of the total eligible project costs in their applications. 

ATP and FCT Federal Share remain unchanged at 95%.
