Overview

• American begins removing carry-on sizers from gate areas nationwide on Oct. 6 to simplify boarding.
• The airline says size rules are not changing, framing the shift as a move to make boarding more efficient.
• Bag sizers remain available in lobby and check-in areas, and oversized items must still be checked before flying.
• Employees have been instructed to err on the side of the traveler when uncertain about a bag’s fit in overhead bins.
• American positions the update as part of earlier 2025 boarding enhancements, and the move mirrors United’s 2020 removal of gate-side sizers.
