This legislation aims to modify the criteria for airports to qualify for an increased federal share of project costs. It specifically amends section 47109(f) of title 49, United States Code, which pertains to the United States Government's contribution to airport development projects. The bill expands eligibility for this special rule to include airports that are currently receiving Essential Air Service , for which air carriers receive compensation. Furthermore, it extends eligibility to airports located in a territory of the United States that were designated as eligible points under the Federal Aviation Act of 1958 as of October 24, 1978. These changes are intended to provide greater financial assistance for airport infrastructure in these specific communities.
