Carry-On Luggage Getting Smaller? IATA's Proposal Shelved After Airline Backlash
The International Air Transport Association (IATA), a leading airline trade group, recently proposed stricter guidelines for carry-on luggage to standardize sizes and improve boarding efficiency.
The recommended "optimal" dimensions are 21.5 inches tall by 13.5 inches wide by 7.5 inches deep—slightly smaller than the typical U.S. airline allowance of 22 x 14 x 9 inches.
IATA argues this would ensure sufficient overhead bin space for all passengers, reducing delays for late boarders. As airlines add more seats, shrinking legroom, and introduce fees for amenities, bin space has become a growing concern. Budget carriers like Spirit and Frontier already charge for carry-ons.
In practice, many travelers might need to purchase new bags or pay to check luggage. IATA plans a "Cabin OK" badge for compliant bags, but a review of Samsonite's 24 carry-on rollers shows none currently meet the proposed sizes.
While airlines aren't obligated to adopt these guidelines, they could influence future policies, potentially deeming existing carry-ons oversized.
