Carry-on vs. Checked Luggage: What You Can Bring Onboard a Flight

Carry-on luggage refers to the bags you bring with you into the cabin of the airplane. Airlines have strict limitations on the size and weight of a carry-on bag to ensure that all passengers can fit their belongings in the overhead compartments or under the seat in front of them. Exact dimensions vary by airline, but make sure your bag’s measurements are including handles and wheels since they’re counted.

A well-chosen carry-on suitcase should be lightweight and durable, with compartments that make packing more efficient. Many travelers opt for a hardshell suitcase, as it provides extra protection for fragile items. Soft-sided luggage, on the other hand, may offer more flexibility if you need to squeeze it into a tight space. If you prefer hands-free travel, a carry-on backpack is a great alternative to a traditional rolling bag.

When selecting the best carry-on luggage, consider features such as built-in USB charging ports, expandable compartments and TSA-approved locks. If you're looking for the best luggage for international travel, keep in mind that some international airlines have smaller size restrictions than domestic carriers. Checking these details in advance can help avoid unexpected fees or the inconvenience of having to check your bag at the gate.

In addition to a carry-on bag, most airlines allow passengers to bring a personal item, such as a purse or laptop bag. This item must fit under the seat in front of you, and while there are no universal size limits, airlines typically specify dimensions on their websites. A personal item is a great place to store valuables, electronics like tablets or laptops, as well as items you may need easy access to during the flight, such as snacks, headphones or a book.

A cabin bag or small suitcase may qualify as a personal item, but it's important to check airline policies to ensure it meets size requirements. Some travelers use backpacks and bags as their personal item, which allows for additional storage and convenience when navigating airports. Parents traveling with young children often bring kids luggage designed to fit under the seat, providing easy access to toys, snacks and essentials during the flight.

For those traveling with more than just a carry-on, checked baggage is an option. Checked luggage is stored in the aircraft’s cargo hold and is typically subject to weight and size restrictions. Travelers who need to pack more clothing, shoes or bulky items may find a large suitcase or medium suitcase ideal for this purpose, but be sure to check your airline’s guidelines for luggage weight, dimensions and volume.

Many travelers invest in luggage sets to accommodate different trip lengths and packing needs. A luggage set typically includes a carry-on suitcase, medium suitcase and large suitcase, giving travelers the flexibility to choose the right bag for each trip. When selecting the best luggage for checked baggage, durability is key. Hardshell suitcases offer superior protection against rough handling, while soft-sided suitcases may expand to accommodate extra items.

Airlines charge fees for checked luggage, which can vary based on the airline, destination and ticket class. Some international flights include free checked baggage allowances, while budget airlines may charge for every bag. Understanding these fees before booking your flight can help you plan accordingly and avoid surprises at the airport.

Certain items are restricted in carry-on luggage but allowed in checked bags. For example, liquids in carry-on bags must adhere to the 3-1-1 rule, meaning each container must be 3.4 ounces (100 milliliters) or smaller, all containers must fit into a single quart-sized bag, and each passenger is allowed only one such bag.See Disclosure ¹ Items such as large bottles of shampoo, full-size perfumes and certain travel gear should be placed in checked luggage to comply with security regulations.

Sharp objects, sports equipment and many tools are also prohibited in carry-on luggage. If you need to bring these items, they must be packed in checked baggage. Electronics such as laptops, tablets and cameras are generally best kept in a carry-on bag to prevent damage or loss. Travelers should also be aware of airline policies regarding lithium batteries, as these must often be carried in the cabin rather than checked due to fire risk.

Choosing the right luggage and travel accessories can make packing more efficient and stress-free. Rolling clothes instead of folding them can save space and prevent wrinkles. Packing cubes are another great tool for organizing clothing and separating clean and dirty items. Travelers with kids luggage should pack essentials such as snacks, toys and a change of clothes in an easily accessible compartment.

For those using a carry-on backpack, balancing the weight distribution is important to ensure comfort while carrying it. Heavier items should be placed at the bottom or closest to the back panel. A backpack with multiple compartments can help keep travel documents, electronics and other necessities well-organized.

Understanding airline baggage policies can make a significant difference in the travel experience. Whether you prefer a carry-on suitcase, a cabin bag or a checked large suitcase, selecting high-quality travel luggage and bags can enhance convenience and durability. The best carry-on luggage should fit within airline size limits, offer sufficient space for essentials and be easy to maneuver through crowded airports.

For frequent travelers, investing in luggage sets may be a smart choice, providing different options for various trip lengths and needs. A medium suitcase works well for shorter trips, while a large suitcase is ideal for extended travel. Those who prioritize mobility may prefer a carry-on backpack or small suitcase that is lightweight and easy to carry. With so many options, a luggage set could even be a great gift idea for travelers in your life.
