Traveling can be exciting, but packing can be the opposite of such an experience. When packing for flights, knowing the rules and regulations is essential to avoid any unnecessary stress.

One common question that many vacation-goers ask is, “Can I take a 22.5-inch carry-on bag on an airplane?” Let’s take a closer look at this question and provide an answer to ensure a smooth and stress-free travel experience.

The Standard Carry-On Bag Size

Nearly all airlines limit the maximum length of a carry-on bag or suitcase to 22 inches. It’s crucial to note that these restrictions are put in place to accommodate an airplane’s overhead storage space and cabin size.

For example, Air Canada’s carry-on baggage size is 21.5 x 15.5 x 9.0 inches, while American Airlines and Delta’s carry-on baggage size is 22.0 x 14.0 x 9.0 inches. British Airways’ carry-on baggage size is 22.0 x 18.0 x 10.0 inches.

Can I Take a 22.5-inch Carry-On Bag?

For the most part, you can get away with flying with a 22.5-inch carry-on bag unless the airport checks the size with a cabin-bag-inspect tool. Even then, if you’re traveling with a backpack or softside suitcase, you can squish your carry-on into the cabin-bag-inspect tool.

However, following the airline’s carry-on baggage restrictions is best if you want to avoid risking it.

Remember, while it may seem like a slight discrepancy, it’s essential to consider the airline’s point of view regarding cabin space issues.

Airport Security and TSA

Airport security or TSA will not care if your carry-on is one inch bigger. They mainly focus on the security of your luggage and ensuring it doesn’t contain any hazardous or prohibited items.

Airport security may advise that you check your bag if it’s more than 22 inches, based on whether or not your airline will allow you to fly with your bag on board. So, if you’re concerned about baggage size, reviewing your airline’s baggage policy beforehand is wise.

Traveling with Other Baggage Items

If you’re traveling with other baggage items such as a backpack, laptop case, or purse, take note of their sizes to ensure that you don’t exceed the weight and size limit.

If you exceed your weight or size limit, they may check your baggage, and you’ll incur a costly overweight baggage fee. Some airlines are strict regarding carry-on baggage policies, but others are more lenient.

It’s vital to remember that every airline differs in their baggage restrictions; it is best to review them carefully before your journey.

Traveling can be stressful, but packing efficiently and effectively can help alleviate some of those stresses.

In conclusion, you will likely get away with taking a 22.5-inch carry-on bag for your flight, but it’s best to ensure you follow your airline’s carry-on baggage regulations.

Remember that airport security and TSA do not regulate the size of your luggage unless there’s a security concern.

For a stress-free experience, confirm the baggage size restrictions of your airline ahead of time and travel light for your next adventure.
