Airlines Enforce Stricter Carry-On Rules, Triggering Unexpected Gate-Check Fees
Airlines are increasingly enforcing strict carry-on baggage policies, leading to surprise gate-check fees for many passengers. Certain features, such as non-removable lithium batteries in smart bags, can result in the luggage being automatically rejected from the cabin. Even standard elements like wheels and handles can cause a bag to exceed the sizer's dimensions, forcing a mandatory check. These last-minute fees can be substantial, often costing up to $100, particularly on low-cost carriers. Travelers are therefore urged to verify their airline's specific baggage rules to avoid these costly charges at the gate.
