Even if your carry-on bag fully complies with the airline’s size and weight requirements, there is no guarantee that it will travel with you in the cabin. Airlines are increasingly conducting checks at the boarding gate, asking passengers to surrender their carry-on luggage so that it can be transported in the aircraft’s cargo hold.
According to industry experts, this practice is not solely related to the size or weight of passengers’ luggage. It is also driven by operational considerations involving flight safety and the aircraft’s weight and balance management.
According to the International Air Transport Association (IATA), most airlines set a maximum carry-on baggage size of 56 × 45 × 25 centimeters, including wheels and handles. In some cases, weight restrictions also apply, starting from 5 kilograms.
However, even when baggage complies with the rules, airlines may still ask passengers to check it in before boarding. One key reason is aircraft weight distribution. As cabin crew members explain, the proper balance between the weight in the cabin and that in the cargo hold is critical for takeoff and landing.
Space availability in overhead bins also plays an important role. On high-load flights or on smaller aircraft, the available overhead space is often insufficient for all passengers’ carry-on luggage, resulting in some of it being transferred to the cargo hold.
Airlines assure passengers that gate-checked baggage is properly tracked using special tags and barcodes, allowing it to be located in case of delays or loss. In many cases, such bags are even among the first to appear on the baggage claim carousel at the final destination.
However, passengers retain the right to keep with them items that are not permitted in the cargo hold, such as laptops, electronic devices containing lithium batteries, power banks, and essential medication. For this reason, it is recommended to remove all valuable or essential items before checking in a bag.
Policies vary from one airline to another. British Airways, for example, allows one carry-on bag up to 56 × 45 × 25 centimeters, while noting that it may be transferred to the cargo hold if necessary. easyJet, Ryanair, and Jet2.com also apply specific size and weight limits, with additional charges for larger carry-on bags.
Experts recommend that travelers check each airline’s policies before every flight, especially when flying with low-cost carriers or on high-occupancy flights, as gate-checking carry-on baggage has become a common practice in international air travel.
