The size and type of hand luggage allowed depends on the airline company's rules. However, the variations from one airline to another are very minimal. In general, an airline imposes a hand luggage limit of up to 45 inches of total bag dimension. The maximum weight usually ranges from 15 to 40 pounds, depending on the airline and whether the passenger is traveling in a local or international destination.
The hand luggage must fit the aircraft cabin's stowing area or storage compartment as well as fit under a passenger's seat. It is also important that all items remain with the passenger or it may be identified as a security risk. Hand luggage must comply with X-ray screening requirements and other security measures. Although travelers are allowed to take electronic items such as laptops and cameras, these items must be removed and screened separately at the airport.
Apart from electronic items, which you are encouraged not store in your checked baggage due to risks of damage from handling, you are also allowed to bring musical instruments and sports equipment with your carry-on baggage allowance. However, when exceeding the allowance, you may either pay additional rates or decide to exclude said items from the flight. Essential medical equipment is also allowed as long as you can present valid supporting documentation from a qualified medical professional.
A limited quantity of liquids, gels and pastes can be included in the hand luggage. The comprehensive list and descriptions for such regulated items is typically available at an airline's official website, along with other key baggage information and policies.
