Southwest Airlines has introduced strict enforcement of bag size limits, sparking passenger complaints. Gate agents are now using tape measures on carry-on luggage—leading to surprise fees for many travelers. This shift comes as the carrier rolls out checked-bag charges, eliminating its longtime free policy. Increased enforcement reflects pressure from investors and a drive to boost ancillary revenue. Experts caution that tighter checks on bag sizes and carry-on limits may slow boarding and frustrate customers. The changes mark a significant shift in Southwest’s customer-friendly culture and service model.
