American Airlines Eliminates Carry-On Bag Sizers at Boarding Gates

Starting October 6, 2025, American Airlines will remove metal bag sizers from its boarding gates across the United States. This decision allows passengers to board without the requirement of fitting their carry-on luggage into a size-checking device. The airline confirmed this change in an internal memo, stating the goal is to "enhance the boarding process."

Despite the removal of bag sizers at the gates, American Airlines maintains that carry-on bags must not exceed 45 linear inches. Passengers are still permitted one carry-on bag for the overhead bin and one personal item that fits under the seat. The airline has instructed staff to "err on the side of the customer" when assessing bags that may appear slightly oversized, allowing for minor overages such as small front pockets or wheels.

This policy shift follows a similar move by United Airlines, which eliminated bag sizers at boarding gates in 2020. The trend reflects a broader industry movement towards more flexible carry-on policies aimed at improving customer experience. Former American Airlines CEO Doug Parker, who served from 2001 to 2023, often advised against checking bags to minimize travel complications, a sentiment that appears to influence this change.

The removal of bag sizers is expected to benefit travelers who often overpack to avoid checked bag fees. However, the airline has emphasized that gate agents will still be vigilant for oversized bags attempting to bypass security. The memo encourages agents to proactively identify oversized luggage in the lobby, where bag sizers will remain in use, to reduce the likelihood of gate-checks.

While many travelers may welcome the change, there are concerns regarding the potential for disputes at the gate. Without a physical sizer, gate agents will rely on their judgment, which could lead to inconsistencies in enforcement. Passengers may argue that their bags fit on previous flights, complicating the boarding process. Critics point out that the absence of a standardized measurement tool could result in confusion and disputes over bag sizes.

American Airlines has reiterated that the maximum size limit for carry-on luggage remains unchanged. The airline's internal memo highlighted the importance of balancing customer convenience with the need to monitor oversized bags effectively. The airline aims to streamline the boarding experience while ensuring compliance with existing size restrictions.

As American Airlines implements this new policy, the airline will monitor its impact on boarding efficiency and customer satisfaction. The effectiveness of this change in reducing disputes and enhancing the travel experience will be evaluated over time, as passengers adjust to the new boarding procedures.
