If you plan to travel in 2025, you will do well to remember that determining your carry-on luggage size is nearly as significant as determining where you are headed. After all, changes surrounding airline carry-on size occur faster than flight schedules change.
Whether you're flying cross-country or in pursuit of a bucket-list international adventure, understanding these size limits can save you the time and frustration of rechecking at the gate—or worse, shelling out cash to get your bags checked.
So let's break down what airlines allow, don't, and how you can pick the best international carry-on luggage without questioning every dimension.
Airlines are now cracking down on cabin space. Not so long ago, an oversized bag could still pass by with a frown, but this is no longer the case. Almost every airline maintains strict guidelines regarding carry-on luggage size and measure—yes, they even measure this down to the wheels and handles.
Most US air carriers adhere to the standard of 22 x 14 x 9 inches. When going abroad, however, it gets complicated. European and Asian carriers tend to have strict limitations, averaging around 21.5 x 13.5 x 7.5 inches. Why? Because the planes are smaller, and the weight balance is given more importance.
Nope. A 24-inch suitcase can't be used. "Can I carry on my 24-inch bag?" is a frequently asked question. Sorry, folks: most airlines don't take big carry-ons, and that size can definitely attract international attention. Save yourself the headache and keep your carry-on to size.

Carry-on regulations are no exception to the airlines' fondness of small print. The majority of airlines followed the previous 22 x 14 x 9-inch guideline, however it's important to note the following exceptions:
American Airlines: Make sure your personal belongings, such as a backpack, can fit beneath the seat.
Southwest Airlines: With dimensions of 24 x 16 x 10 inches, Southwest Airlines is surprisingly generous and ideal for heavy packers.
Spirit Airlines: 22 x 18 x 10 inches gives you a little extra space, but be mindful of their weight restrictions.
When traveling abroad, make sure to plan ahead. In reality, British Airways, Lufthansa, and Emirates are somewhat more constrained in their size and strictly enforce the cap.
Why is a few inches such a big deal? It's about efficiency, not about space. There is pressure on airlines to expedite boarding, reduce wait times, and maintain the highest level of passenger comfort. Larger luggage creates delays, and no one wants to be the one causing difficulty by preventing others from moving forward because their bag doesn't fit in the overhead bin.
Then there's the burden. International carriers weigh carry-ons, with limitations ranging from 15 to 22 pounds, but the majority of U.S. airlines do not. Therefore, it is impossible to choose the finest international carry-on baggage that is lightweight, small, and compliant.
Not every piece of baggage is the same. The ideal carry-on relies on a number of factors, including size, usefulness, durability, and ease of rolling through airports. This is a shopping list for a new bag:
Light Materials: Naturally, hard-shell polycarbonate is utilized for a reason—it is durable without adding weight.
Expandable Options: Better for domestic travel, but exercise caution when traveling abroad when space is an issue.
Smooth Wheel: Investing in four-wheel spinners will benefit your shoulders, and keep you relaxed.
TSA-Approved Locks: A little tranquility of mind makes a big difference during your travel.
For 2025, companies like Samsonite, Away, and Travelpro are still setting the bar high. In addition to meeting carry-on size requirements, their baggage consistently looks fantastic and doesn't compromise on aesthetics for storage capacity.
Packing for a trip takes thought and strategy, as stringent airline restrictions only get stricter. Carry-on bags are allowed onboard if they meet size and weight requirements without sacrificing personal essentials.
Pack Multi-Use Clothing: To take advantage of carry-on space, focus on packing clothes with multiple uses. Pack items that can be mixed and matched to create different outfits. Neutrally-colored tops, wrinkle-free pants, and a light jacket are all good examples of clothes that can be repeated. Consider the fabrics that can breathe but are not necessarily difficult to wash during travel. Some good options include merino wool or synthetic blends.
Mastering the Art of Packing Cubes: Once said and done, nothing beats organization and hence space management better than packing cubes. Use different cubes for clothes, undergarments, and accessories. Compression cubes that can shrink the volume of your sweaters can also help you find space for other items.
Roll Rather Than Folding: Rolling clothes can save space besides preventing wrinkles. It is good for items such as t-shirts, leggings, and lightweight dresses. Delicate fabrics could be rolled along with tissue paper for protection.
Follow the 3-1-1 Rule of the Transportation Security Administration: Pack liquids in 3.4-ounce bottles or less and place them in a quart-sized ziplock bag. Place the bag within easy reach to enhance security line speed.
Weigh Your Baggage: Take your carry-on luggage to the airport and weigh it with a handy luggage scale. Most international airlines have implemented strict weight limits on carryons.
By following these simple tips, you can make packing relatively straightforward while guaranteeing a stress-free journey.

Carry-on luggage rules of various regions can be a little tough to navigate while traveling internationally. The policies at most airlines vary regionally, so here are five essentials. Five Key Tips to Prepare for International Flights
Unlike local airlines, most international airlines impose size and weight limitations. While U.S. airlines tend to not weigh carry-ons, international airlines may limit the weight to 15-22 pounds. Measure and weigh your luggage before flying out to avoid surprise fees or hassle of repacking at check-in.
Every region has its luggage policy oddities.
Europe: Most airlines have smaller dimensions for carry-ons; most are about 21.5 x 15.7 x 9 inches. Budget airlines, like Ryanair, will charge extra for items over their strict personal item allowance.
Asia: Many airlines in Asia have size, as well as weight, restrictions. Some, like AirAsia, limit the weight of carry-on luggage to 15 pounds.
Middle East: Airlines here, such as Emirates, are more spacious, but double-check connecting flight requirements.
When traveling overseas, consider ultra-light carry-on bags. A light design provides for as much weight as possible for your clothing and other items and is airline compliant. Look to polycarbonate or nylon for durability without added bulk.
Many international airports go by the 3-1-1 rule: liquids must be in containers of 100ml or less and placed in a transparent quart-sized bag. Do not forget that other countries, including Britain and Australia, have tighter security and even duty-free liquids can't make an exemption.
If flying through several countries, be aware that each airline and region may have unique policies. Ensure to check out the carry-on allowances for all segments of your trip in advance to avoid shocks.
A 24-inch suitcase typically is too big for most airlines to be considered a carry-on. Southwest Airlines does allow slightly larger bags, but any bag larger than the standard 22 x 14 x 9 inch limit will likely be checked by most airlines.
Weight limits differ significantly. U.S. carriers do not weigh carry-ons, but many international airlines do, with most between 15 and 22 pounds.
Personal items include anything small enough to be stowed under a seat, such as backpacks, laptop cases, or purses. They are usually not bigger than 18 x 14 x 8 inches in size.
The secret to hassle-free travel in 2025 is to stay up to date on carry-on luggage sizes. To save needless costs and travel-related stress, buy the appropriate luggage, prepare carefully, and review airline restrictions.
Keep in mind that the finest journeys start with planning. Your carry-on is your traveling companion, not just a bag. Thus, if you take good care of it, it will return the favor.
