Though rules can vary by airline, most allow only one carry-on bag per person.
International travel requires a great deal of planning, even when considering your luggage. Many item restrictions are different for each airline, but there are some general rules you can follow. Taking smaller than normal bags and limiting your items down to necessities will help prevent any difficulties. Always make sure to verify your airline's specific guidelines before your trip to prevent any problems checking in.
Carry-On Baggage
A rule of thumb for carry-on baggage is to have a maximum size of 45-inches. This number represents the total of the dimension measurements, for example a standard carry-on suitcase measuring 22-inches by 14-inches by 9-inches. Most airlines only allow one of these per passenger, though this depends on the carrier. Policies regarding these items tend to be stricter when traveling internationally so taking luggage smaller than the normal domestic requirements will help you avoid any problems. Though it's not common for domestic flights to have weight restrictions on carry-on items, international carriers can occasionally have limits on this type of baggage.
Personal Items
Most airlines allow one personal carry-on item in addition to your carry-on suitcase such as a backpack, purse or laptop. Specific lists can be verified with your carrier. This personal item must also be small enough to fit underneath the seat and shouldn't exceed a total dimension of 36-inches. As with carry-on luggage, international policies tend to be stricter with such items.
Checked-In Baggage
Rules on the size, weight and number of checked bags differ by airline. Most U.S. flights allow two checked-in bags, with additional charges if they exceed the airline's specific weight limits. Internationally though, airlines tend to operate on a weight system, ignoring the actual number of items. This weight can vary from around 44 to 88 lbs. per person, usually depending on the class of your ticket.
Prohibited Items
There are a number of items that you are prohibited from bringing onto any commercial airliner. The Transportation Security Administration's list includes more obvious items like firearms, sharp objects, flammable materials and harmful chemicals. Also banned is defensive weaponry like the items used in martial arts. Other restricted items include some tools and sporting goods like hammers and baseball bats.
Changing Policies
Airline policies can change, particularly in an age of anti-terrorism and cautious air travel. It is important to know updated policies before traveling. You can check the Transportation Security Administration's current policies as well as your airline's specific rules and regulations to ensure a trouble-free trip.
