The chosen figure ensures stable takeoffs and landings, simultaneously reducing the airline's fuel expenses.
Exploring the Logic Behind the 7kg Restriction for Carry-on Luggage
Excess baggage is always a nightmare for air travelers using airline services. Penalties for non-compliance with regulations on the weight and dimensions of carry-on luggage are often high in Vietnam, ranging from 500,000 dong to millions for each excess kilogram.
According to the regulations of most airlines worldwide, the dimensions for items brought onto the plane are 20 x 40 x 55 cm, with some variation, and the weight ranges from 5-10 kg, commonly set at 7 kg. However, some airlines are quite lenient, allowing passengers in certain ticket classes to bring up to 20 kg of carry-on luggage.
Ensuring Weight Compliance
According to airlines, regulating the weight and dimensions of items is crucial for ensuring safe flights based on the size and load-bearing capacity of the carry-on luggage compartment (depending on the aircraft type). Among the various types of civil aircraft produced globally, the Boeing 777 can accommodate a minimum of 300 seats. The most advanced model is the Airbus A380 with over 800 seats.
Scientists have calculated the weight of the passenger compartment (above), cargo compartment (below, used for checked luggage), balancing the number of passengers, along with parameters related to the aircraft's wings, engines, etc. The chosen figures fall within the limits to ensure stable take-offs and landings. For airlines allowing more carry-on weight, the number of passengers has been appropriately calculated.
Easy Self-Transportation
A weight range of 7-8 kg is suitable for transporting luggage for an individual with a normal physique. You can lift, lower, and move your luggage easily. Some studies indicate that the size and weight of items determine the time passengers take to board the aircraft. If your suitcase or bag is too large or oversized, self-transportation can be challenging, sometimes causing delays and affecting takeoff schedules.
Some airlines in China only allow 5 kg per person. One reason is that airports in the country are consistently overloaded. Passengers with fewer items facilitate quicker movement, saving time for the entire airport operation.
The dimensions 20 x 40 x 55 cm have also been calculated to be suitable for the overhead luggage compartment, ensuring they can fit snugly, preventing items from falling out and posing a danger while the aircraft is in motion.
Fuel Efficiency
In addition to scientific considerations, civil airlines, before establishing regulations on carry-on luggage, also take into account ensuring fuel efficiency. Restricting the weight of passengers' items is one of the effective measures. If the aircraft carries too much luggage, it can lead to increased fuel consumption and higher costs. As a result, ticket prices may need to change and may no longer be appealing to passengers.
To avoid fines for overweight luggage, careful planning is necessary to prevent inconvenience and time-consuming troubles. Apart from size and weight, carry-on luggage is subject to strict regulations, such as not containing metal, explosive materials, liquids, etc. Each airport has free luggage measuring trays. Before checking in, weigh and measure your items to ensure they comply and avoid unjust fines.
