Airline policies regarding minor weight overages, such as a single kilogram, vary significantly depending on the carrier's specific tariff rules and the demeanor of the check-in agent. While many airlines strictly enforce published baggage weight thresholds, some agents at their discretion may allow a minor margin of error for a single kilogram, particularly for loyal frequent flyer program members. However, passengers should never assume this leniency; airlines are within their legal rights to charge excess baggage fees for any weight exceeding the allowance stated on the ticket. To avoid such unexpected charges at the airport, it is advisable to weigh your luggage thoroughly at home prior to arrival or shift small items into your carry-on bag if the total weight limit allows for it.
