JETSET Costs Act of 2023

This bill requires the Secretary of Transportation and their executive staff to use commercial airlines instead of Department of Transportation (DOT) aircraft unless the DOT flight is at least 5% cheaper. It mandates DOT to calculate true per-seat costs (excluding different rates for non-DOT officials) and report all such travel to Congress annually, including justification for each DOT flight. The law prohibits personal or political use of DOT aircraft for these officials and requires the DOT Administrator to revise internal cost guidelines within 180 days. It directly affects the Secretary’s executive staff and DOT’s travel policies, focusing on cost transparency and accountability for government aircraft use.
