Frontier & Southwest Airlines Allow 24-Inch Carry-Ons, But TSA's New CT Scanners Leave Half An Inch To Spare
New TSA screeners will fit the largest carry-ons on paper, but challenges may arise in practice.
Frontier Airlines and Southwest Airlines are both permitting cabin bags up to 24 by 16 by 10 inches for carry-on travel, aligning with their published size allowances.
The Transportation Security Administration is installing new CT scanners at airport checkpoints, featuring tunnel openings roughly 24.5 inches wide and 16.5 inches high, according to the report.
Because the CT tunnel dimensions exceed the maximum bag size only slightly, a bag that is at the allowed maximum would fit on paper but have only about half an inch of clearance in the two critical dimensions at the scanner entrance.
The article notes the practical implications of this setup for travelers with larger carry-ons, highlighting a potential squeeze at check-in and security screening without specifying any incidents, outcomes, or dates beyond the publication.
