American Airlines is making a major change to the boarding experience. Beginning October 6, 2025, the carrier will remove metal bag sizers from airport gates nationwide — replacing rigid size enforcement with employee discretion. The airline says the move will “simplify and speed up” boarding, aiming for fewer conflicts and a smoother experience for passengers.
The Policy Shift
According to KTLA, the airline has confirmed that the metal sizers, long used to check carry-on dimensions at gates, will be removed across its network. Instead, agents will use their judgment to determine whether a bag fits in the overhead bins. When uncertain, employees are instructed to “err on the side of the customer.” The goal: faster boarding and fewer disputes over bag size.
When the Change Takes Effect
The update officially rolled out on October 6, following weeks of preparation. According to USA Today, the rollout began at major hubs before expanding system-wide. By mid-October, all airports are expected to operate without metal frames at gate areas. Early feedback from test airports shows shorter boarding times and less friction between travelers and staff.
Why It’s Happening
American Airlines said in a statement that the change is part of its plan to “simplify the boarding experience for customers and team members.” In addition to the gate sizer removal, the airline recently added five minutes to boarding time, expanded family preboarding, and implemented digital tools to streamline check-in. Collectively, these changes aim to create a more relaxed pre-flight process.
What Rules Still Apply
Despite the new flexibility, the carry-on policy itself hasn’t changed. Passengers are still allowed one carry-on bag up to 22 x 14 x 9 inches, plus one personal item that fits under the seat. Oversized luggage will still be checked, though now without the rigid metal frames at the gate. Those frames will remain available in check-in lobbies, where travelers can self-verify their bags before security.
A Wider Industry Trend
AA’s decision follows a similar move by United Airlines, which eliminated its own gate sizers back in 2020. United said at the time that the change “reduced tension at boarding zones” and improved overall satisfaction. Aviation analysts say American’s new policy reflects an industry shift toward greater flexibility and customer trust, though consistency remains a concern.
The Role of Discretion and Consistency
Without the metal frames, gate agents now rely on visual judgment to determine if a carry-on fits in overhead compartments. While this can speed up boarding, experts note it could also lead to inconsistencies between flights or airports. Travelers may find that what passes on one route might not on another. Still, the airline believes this approach will create a more pleasant boarding experience overall.
Traveler and Industry Reactions
The change has sparked mixed reactions among frequent flyers. Some travelers, as noted by View From the Wing, see it as a welcome sign of flexibility — suggesting that slightly larger bags may now make it through without issue.
Others, however, have voiced concerns that removing the metal sizers eliminates a clear standard for what counts as “carry-on compliant.” As one report observed, many passengers preferred having an objective rule instead of relying on individual judgment, fearing that enforcement would vary by gate and airport
A Broader Push for Boarding Efficiency
The change to bag rules is part of American’s broader effort to modernize its operations and improve on-time performance. Recent upgrades include restructured boarding groups, expanded preboarding eligibility, and new software tools that optimize gate assignments. Together, these adjustments aim to reduce congestion and make boarding less chaotic across American’s vast domestic network
What Passengers Should Expect
For travelers, this means faster boarding and fewer last-minute gate checks — though the policy still depends heavily on employee discretion and available overhead space. Passengers are encouraged to comply with published size limits and arrive early if unsure about their bag’s fit. American says the new approach “puts trust in the hands of both our team and our customers.”
