Most airlines now charge for checked bags on domestic flights; even so, there are restrictions on the size and weight you may take. Measure your bag to be certain it adds up to 62 dimensional inches or less. For airline purposes, the measurement of one length of the suitcase plus one width, plus one height equals the dimensional inches of the item including any protruding parts such as wheels or handle (in stored position). Domestic weight restriction is 50 pounds. Bags over 62 inches or 50 pounds will incur additional charges. Note: The cost increases with each additional checked bag. Even if you are willing to pay for several bags, check with your carrier to see if they limit how many you can check. For instance, Delta Airlines limits the number of checked, paid bags to four per passenger.
Generally, the domestic baggage size and weight restrictions apply to international travelers, except when traveling to Brazil you have a 70 pound allowance. On many flights you may check up to two bags at no charge. Exceptions include flying to or through Europe and India, where you are allowed one free checked bag. Flights to Canada are under the domestic travel baggage rules and you will be charged to check a suitcase. The international no charge for checked bag rule also applies to domestic flights en route to international destinations. For instance, fly from Dallas-Fort Worth International Airport to Los Angeles with your checked bags at no charge when taking a connecting flight from Los Angeles to Taiwan.
Consider using a sturdy corrugated box instead of a suitcase. Weigh the empty suitcase. Chances are it weighs three to seven pounds. Pack in a box to take advantage of the pounds gained from a lighter receptacle. The same size and weight restrictions apply for domestic or international travel, contact the airline regarding your specific international destination to be certain boxes are allowed. A box might be useful when taking business-related papers and equipment or gifts that will not be returning home with you.
If you need to transport specialty items such as infant seats, firearms, musical instruments, sports equipment or mobility equipment, check with the airline you will be utilizing to see what packaging and charges apply.
The Transportation Security Administration (TSA) restricts items in checked baggage as well as in carry-ons. Certain items may be allowable in checked bags (for example, crowbar, pellet gun, arrows) that are not allowed in carry-ons. For a complete list of prohibited items, use the link below in references. Explosives, chemicals, flammable items are not allowed in any baggage.
