The term hand luggage or cabin baggage (normally called carry-on in North America) refers to the type of luggage that passengers are allowed to carry along in the passenger compartment of a vehicle instead of a separate cargo compartment. Passengers are allowed to carry a limited number of smaller bags with them in the vehicle, which typically contain valuables and items needed during the journey. There is normally storage space provided for hand luggage, either under seating, or in overhead lockers. Trains usually have luggage racks above the seats and may also (especially in the case of trains travelling longer distances) have luggage space between the backs of seats facing opposite directions, or in extra luggage racks, for example, at the ends of the carriage (train car in American English) near the doors.
Hand baggage allowance is a topic frequently discussed in the context of commercial air travel. On the one hand, passengers may want to have more of their possessions at hand during flight, skip the often time-consuming baggage claim process, and avoid the risk of having their checked baggage lost or damaged. On the other hand, safety concerns, takeoff weight limitations, and financial incentives (e.g. charging for checked bags) cause airlines to impose limits on how much and what passengers can take into the aircraft cabin. A large amount of hand luggage also slows the security screening of passengers, and can slow boarding as it takes longer to find space in cabin storage areas.
Studies have found that passengers often pause to retrieve cabin baggage during an emergency evacuation, despite instructions to the contrary in pre-flight safety briefings. This is not a new phenomenon, as it was observed during the evacuation of a Boeing 737 that caught fire in 1984. At least one passenger re-entered a Boeing 777 that crashed in 2008 to retrieve personal belongings. Video of the evacuation of a Sukhoi Superjet that caught fire on landing in 2019 clearly shows passengers on the emergency slides with large suitcases, raising questions as to whether this contributed to the loss of life. Remote locking of overhead baggage bins is being considered as a solution to the issue.
The International Air Transport Association (IATA) sets guidelines for cabin baggage/hand luggage/carry-on luggage size. As of 2022, the IATA recommends a maximum size of 56 cm × 45 cm × 25 cm (22 in × 18 in × 10 in), including protuberances like wheels, handles, and pockets.
The IATA guidelines are voluntary; the actual size and weight limits of cabin baggage imposed by airlines differ widely. In some cases they are dependent on the aircraft model being used, in other cases it depends on the booking class.

Dimensions are sometimes listed as "linear", meaning that when added together, height, width, and length are not to exceed a certain total number.
Business class, first class passengers and holders of high level mileage club members are often allowed to carry on a second bag of a similar or smaller size and weight.
On smaller sized aircraft, sometimes the hand baggage can be carried to the aircraft door, where it is collected by baggage handlers for stowing in the cargo area and returned to the passenger right after landing.
Following the increase in restrictions imposed on flights from UK airports and to the US after the events of August 2006 transatlantic aircraft plot, hand baggage on such flights was restricted to one cabin bag no bigger than 45 cm × 35 cm × 16 cm (17¾" x 13¾" x 6¼") effective since 15 August 2006. On 21 September 2006, the British Airports Authority advised that from the following day, the allowable size of the single item of hand baggage on outgoing flights from the UK would be increased to 56 cm × 45 cm × 25 cm (approx. 22 in × 17.75 in × 9.85 in), the IATA guideline size. Most UK airports still have a strict limit of one piece of cabin baggage per passenger, including business class.
A common regulation for cabin baggage restrictions was introduced on 6 November 2006 in European Union and in Switzerland, Norway and Iceland.
The United States Transportation Security Administration (TSA) has introduced a series of restrictions effective since 26 September 2006 under the name "3:1:1" for liquids.
The TSA has additional restrictions for security searches: for example, the baggage should not be locked (except with a special luggage locks that TSA staff can open), gifts should not be wrapped, and shoes may be required to be taken off during body search with the metal detector. Food items in the luggage may be mistaken for dangerous material triggering an intensive search.
