When it comes to air travel, packing can be a challenging task, especially when it comes to choosing the right suitcase size. Many travelers often need clarification on what size suitcase is allowed on a plane.

Airlines have varying rules and restrictions when it comes to luggage, and it’s crucial to understand them to avoid unnecessary fees or last-minute hassles. In this article, we will explore what size suitcase is allowed on a plane and the regulations associated with each.

Carry-on suitcases are the most popular type of luggage for air travel. These are small enough to fit in the overhead compartment or under the seat in front of you. Typically, maximum dimensions are 22 x 14 x 9 inches, including handles and wheels. Airlines may have different size restrictions, so checking with your airline before traveling is best.

It’s essential to note that if your carry-on suitcase exceeds the airline’s size limit, you may be asked to check it in at the gate, which could incur additional fees. Additionally, the airline may require you to check in your carry-on suitcase if the overhead compartments are full.

Checked Suitcase Size

Checked suitcases are larger and must be checked in at the airport before your flight. The maximum size allowed for a checked suitcase is typically 62 linear inches (length + width + height). However, many airlines also have a weight limit for checked luggage, which is usually around 50 pounds.

It’s important to note that if your checked suitcase exceeds the size or weight limit, you may be charged additional fees or required to repack some items into another suitcase. It’s best to check with your airline for specific regulations regarding checked luggage.

Oversized Suitcase Size

If you need to travel with oversized luggage, such as sports equipment, musical instruments, or other bulky items, you may need to pay additional fees or make special arrangements with the airline. Oversized suitcases usually exceed the airline’s maximum size limit for checked luggage.

Some airlines may allow oversized luggage, but you’ll need to contact them in advance to make arrangements. Keep in mind that these arrangements may come at an additional cost, so be sure to budget accordingly.

Can 24-Inch Luggage Be Carry-On?

The answer depends on the airline and their specific carry-on luggage restrictions. Generally, the maximum size for carry-on luggage is 22 inches long, 14 inches wide, and 9 inches deep, including wheels and handles. However, some airlines may allow slightly larger sizes, so it’s always best to check with your airline before you travel.

Can I Take 2 Bags as Hand Luggage?

Again, this depends on the airline’s rules. Most airlines allow one piece of hand luggage and one personal item, such as a purse or laptop bag, but some may allow two pieces of hand luggage. It’s important to check with your airline’s website or customer service before traveling to avoid any airport issues.
