Pack lightly
Heavy luggage can impact the weight of the aircraft and requires more fuel, so be sure to pack light, taking only the essentials that you will need for your trip. If every passenger reduced the weight of their baggage this could help reduce the amount of fuel needed for flights. In fact, one airline calculated that by lightening the load of every plane by just 0.45kg, they could save 53,000 litres of fuel every year!
