International flights tend to have more regulations on bags, according to The Travel Insider. The size and weight of a carry-on bag is highly restricted for airlines to maximize their space on board. Be aware of your specific airline's rules for carry-on bags. Some airlines require all carry-on bags to fit securely under the seat in front of you. The size of the aircraft plays a part in the luggage size regulations. Some airlines limit passengers to 20 pounds of luggage including carry-on and checked-in items. The Travel Insider describes two major systems in checked bag allowances. For flights to or from the U.S., passengers are typically allowed two pieces of checked luggage, each weighing up to 70 pounds. However, flights throughout the rest of the world differ in weight limitations. Some international airlines limit passengers to a maximum weight of 20 kg or 44 lbs. It is best to check with your airline about international size and weight rules before packing for your trip.
International flights typically allow passengers to bring one bag aboard the plane, plus one personal item. Fliers may not be aware of what the term "personal item" includes. The Travel Insider provides a list of acceptable personal items for international flights. Passengers may bring a briefcase, handbag or purse and a laptop bag as their additional carry-on item. A camera, umbrella and small book or newspaper is also acceptable to take aboard the aircraft. Items typically smaller than 36 inches in total dimension are considered personal items. Passengers with medical requirements like canes and oxygen tanks should inform the airline ahead of time for procedures.
The Transportation Security Administration established a set of prohibited items for domestic and international flights. Some items may be checked-in only and other may be carried aboard only. There are, however, items to avoid taking to the airport completely. Explosive materials such as blasting caps, dynamite, fireworks, flares, gasoline and lighter fluid are strictly prohibited items. Hand grenades and plastic explosives are also prohibited from airline travel. TSA security officials will confiscate these hazardous materials to ensure the safety of the international flight.
