Small Community Air Service Enhancement Act

This bill amends a federal program supporting air service to small communities. It expands eligibility by redefining when air service is considered "significantly reduced" to include factors like passenger numbers, available seats, flight schedules, or routes - not just termination. The bill increases annual funding for the program from $10 million to $16 million (for fiscal years 2024-2028) and requires the Secretary of Transportation to solicit grant applications if over $5 million in available funds exists during a fiscal year. These changes directly affect small communities reliant on federal air service development funds to maintain or restore air connectivity.
