Luggage allowance varies by airline, tour company, cruise line, and destination. It is always best to check your specific requirements before packing for a trip.
However, standard allowance for air travel usually includes one piece of checked baggage, one carry-on bag, and one personal item. This could be a purse or tote bag, briefcase, or laptop computer.
For air travel, the standard measurement for checked baggage is 62 linear inches (L + W + H) with the weight not exceeding 50 pounds per piece. Carry-on bags should not exceed 45 linear inches (L+W+H) with the weight not exceeding 40 pounds. These measurements include the wheels. Airlines outside the United States may have stricter regulations for both checked baggage and carry-on baggage.
Please note that airlines have been strictly enforcing the 50 pound weight limit. If your bag exceeds 50 pounds, the airlines reserve the right to charge a fee for overweight luggage.
For cruise lines, a standard allowance usually includes two larger checked bag style suitcases per person. Please keep in mind that you will need to store your luggage in your cabin during the trip.
For tour companies, especially those that include transfers, one checked bag style suitcase and one personal item is a standard limit.
As always, specific restrictions listed on your documents, or on the provider’s website, are the standards you should follow.
