This bill mandates the Secretary of Transportation to revise existing regulations concerning flight delays. Within 180 days of enactment, the Secretary must issue new rules to amend section 260.2 of title 14, Code of Federal Regulations. The primary change involves reducing the time threshold for a flight to be considered "significantly delayed or changed." For domestic itineraries, this threshold will decrease from three hours to two hours . Similarly, for international itineraries, the definition of a significant delay will be lowered from six hours to five hours , aiming to provide passengers with earlier recognition of substantial flight disruptions.
