DOT ditches race-based perks for airport business aid

2026-18040, Cause of Airline Delay and Cancellation Categories Under Section 511(b) of the FAA Reauthorization Act of 2024

The U.S. Department of Transportation (Department or DOT) is amending its regulations governing how air carriers report the causes of flight cancellations and delays. This action implements Section 511(b) of the FAA Reauthorization Act of 2024, which mandates that ten specific types of events be excluded from the "Air Carrier" causal reporting code. That code is reserved for circumstances that are within the carrier's control. This final rule creates a new reporting category to capture these ten specific events, ensuring that the data reported to the Department and shared with the traveling public accurately reflects the statutory distinction between carrier-controllable events and the specific exclusions identified by Congress.

2026-17904, National Environmental Policy Act Regulations

FHWA, FRA, and FTA (collectively referred to as the "Agencies") are finalizing the interim final rule (IFR) published on July 3, 2025, which revised the Agencies' National Environmental Policy Act (NEPA) of 1969 implementing regulations in light of the removal of the Council on Environmental Quality (CEQ) regulations, the amendments to NEPA included in the section of the Fiscal Responsibility Act (FR Act) of 2023, known as the Building United States Infrastructure through Limited Delays and Efficient Reviews (BUILDER) Act of 2023, amendments regarding efficient environmental reviews included in the Infrastructure Investment and Jobs Act (IIJA) of 2021, and the Supreme Court decision in Seven County Infrastructure Coalition. The Agencies provided a 30-day comment period for the public to review and comment on the IFR. This final rule addresses public comments received and finalizes the IFR with minor technical changes.

2026-15835, Accessible Lavatories on Single-Aisle Aircraft and Ensuring Safe Accommodations for Air Travelers With Disabilities Using Wheelchairs

The U.S. Department of Transportation (DOT or Department) is extending its previously announced enforcement discretion for four provisions of the final rule on "Ensuring Safe Accommodations for Air Travelers With Disabilities Using Wheelchairs" (Wheelchair Rule I) related to airline liability for mishandled wheelchairs, refresher training frequency, pre-departure notifications, and fare difference reimbursements from December 31, 2026 to April 30, 2027. To maintain regulatory consistency, the Department is also expanding this enforcement discretion to include the 12-month hands-on training mandate for flight attendants regarding on-board wheelchair (OBW) assistance and lavatory accessibility in the final rule titled "Accessible Lavatories on Single-Aisle Aircraft" (Accessible Lavatory Rule). These provisions will be formally addressed in an upcoming rulemaking titled "Airline Obligations to Accommodate Air Travelers with Disabilities Using Wheelchairs" (Wheelchair Rule II). This extension is necessary to allow sufficient time for the Department to review and analyze public comments, and to make final determinations regarding the content of the final rule. This exercise of enforcement discretion is intended to remove the burden of complying with the requirements under review by DOT and does not prejudge the outcome of the new rulemaking. This notice does not affect the enforcement of requirements in the Accessible Lavatory Rule other than the one identified.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems

In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.

These updates cut red tape without adding new costs, keeping everyone safer and smoother in the explosive world.
