Keep Air Travel Safe Act

This bill provides continuing appropriations for the Transportation Security Administration (TSA) during any period in which there is a lapse in appropriations for TSA. It also requires the continuing appropriations to be funded using certain unobligated funds that were provided to U.S. Immigration and Customs Enforcement by the One Big Beautiful Bill Act. The bill provides the appropriations for TSA to continue all programs, projects, or activities (including the costs of direct loans and loan guarantees) that were funded in the preceding fiscal year. The appropriations provided by this bill are available from the first day of a lapse in appropriations for TSA until the earlier of the date on which the applicable regular appropriations bill for the fiscal year becomes law or a joint resolution making continuing appropriations becomes law, or the date that is 180 days after the first day of a lapse in appropriations.
