Analyzed Economic Effects

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.
