FAA Makes Airlines Reveal Seat Sizes for Kid Car Seats on Planes
Published Date: 6/17/2025
Notice
Summary
The FAA is renewing a rule that makes airlines share seat width info on their websites to help parents use child safety seats on planes. This affects airlines flying passengers and helps families pick the right seats for their little ones. The public can comment on this for 60 days, and there’s no extra cost for airlines to keep sharing this info.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Airlines must publish seat widths online
Airlines that carry passengers must post on their websites the width of the narrowest and widest passenger seat in each class of service for each make, model, and series of airplane, under 14 CFR Part 121.311. This information is intended to help parents and guardians choose seats that will fit child safety seats on airplanes.
FAA says airlines face no added cost
The notice states there is no extra cost for airlines to continue making seat-width information available on their websites as part of the renewed information collection. That means passenger-carrying air carriers are not expected to incur new expenses to keep sharing this seat-dimension data.

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.
2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2026-19722, IFR Altitudes; Miscellaneous Amendments
Starting October 29, 2026, the FAA is updating the official flying altitudes and switch points for certain air routes to keep flights safe and smooth. These changes affect pilots flying under instrument rules and help avoid radio interference while improving navigation. No extra costs for pilots, just smarter skies and safer flights!
2026-19584, Flight Operations: Pilot requirements; Use of oxygen
The FAA wants to change the rules about when pilots have to wear oxygen masks during flights. Pilots flying commuter, on-demand, and general aviation planes could fly higher without needing to wear masks all the time. These updates aim to make flying easier and cheaper for operators, with comments open until November 23, 2026.
