To amend title 49, United States Code, to clarify airport revenue use of local general sales taxes, and for other purposes.

This bill clarifies that certain local general sales tax revenues can be used for airport purposes without being subject to existing restrictions. It directly affects local governments that met three specific conditions: they had a general sales tax excluding aviation fuel before December 2014, are not airport sponsors, and have a large hub airport (over 35 million passenger boardings in 2021) within their jurisdiction. The key provision modifies federal airport funding rules to explicitly permit these local tax revenues for airport-related expenses. The change applies only to qualifying local governments with these specific historical and geographic criteria.
