Knowing the maximum size for carry on luggage is crucial for any traveler looking to avoid hefty fees and headaches at the airport. Airlines are strict about enforcing their size restrictions, and trying to bring an oversized bag through security or onto the plane can result in being forced to check your bag – often at a high last-minute cost. In this comprehensive guide, we’ll cover everything you need to know about carry-on size limits for major airlines so you can pack with confidence.
Standard Carry On Luggage Size Limits
The most common maximum size for carry on bags amongst major airlines is 22″ x 14″ x 9″ including handles and wheels. This standard was created to fit the bin dimensions on most aircraft. However, it’s important to verify your airline’s specific size allowances as there can be some variations:
- Delta: 22″ x 14″ x 9″.
- American Airlines: 22″ x 14″ x 9″.
- United Airlines: 22″ x 14″ x 9″.
- Southwest: 24″ x 16″ x 10″.
- JetBlue: 22″ x 14″ x 9″.
Most international carriers follow similar size restrictions around 22″ x 14″ x 9″, though Asian airlines like China Southern (20″ x 16″ x 10″) tend to have slightly smaller limits.
It’s also important to note that many airlines have different, smaller size maximums for their premium cabin carry ons compared to economy. For example, Delta’s first class limit is 19″ x 13″ x 9.5″. Therefore, many travelers buy sets of SHOWKOO Luggage in order to use the most suitable suitcase when necessary.
How to Measure Your Carry On Bag
Airlines measure carry on size by taking the total exterior linear dimensions by adding the height, width, and depth of your bag including wheels and handles. Make sure to measure your bag this way at home before traveling.
The easiest way is to use a soft tape measure or measuring device specifically designed for luggage with a flat base to slide under your bag. Lay your bag flat and measure the height off the ground, width, and depth. Then add those three numbers together.
Many airports and airlines also have weight check stations with carry on luggage sizers – rectangular boxes with the maximum dimensions cut out. If your bag fits easily inside, it meets the size requirements.
Exceptions and Additional Fees
Outside of your main carry-on bag, airlines also allow you to bring one personal item like a purse, briefcase, laptop bag, or backpack subject to more restrictive size limits. Common personal item size maximums are 18″ x 14″ x 8″ or smaller.
If your carry-on bag exceeds the size requirements, even by a little, you’ll likely need to pay hefty oversize and overweight baggage fees of $50 or more to check it at the airport. The same applies for specialty items like golf clubs, skis, musical instruments, and other sports equipment that don’t fit in the bins.
Carry On Weight Restrictions
In addition to size, airlines also enforce maximum weight limits for carry-on bags to ensure they are light enough to be safely lifted into overhead bins. While policies vary, a common weight limit for carry ons is 40 lbs.
Most airlines won’t actually weigh your carry on bag unless it looks/feels excessively heavy. However, they reserve the right to require you to check your bag if it exceeds the weight limit, usually with overweight fees applied.
Maximizing Your Carry On Space
To avoid checking a bag, it’s smart to buy carry-on-specific luggage designed to meet major airlines’ size specs. Look for bags around 21.5″ x 13.5″ x 9″ which gives you a little breathing room.
Utilizing packing organizers like compression cubes and folding boards can also help maximize space inside your bag. And don’t forget to use your personal item for extras! A medium backpack or tote can hold umbrellas, jackets, laptops, etc.
Tips for Smooth Travels
Even with the right sized bag, the overhead bins on busy flights fill up fast. Arriving early gives you the best shot at finding space for your carry on in the bin near your seat.
Also consider a luggage style with a slim profile like a duffle or backpack instead of a thick hardshell case. The slimmer your bag, the easier it will slide into tight bin spaces.
Finally, always have a backup plan for checking your bag if you absolutely can’t make it work as a carry on. Checking at the counter is much cheaper than panic-paying a last-minute gate checked bag fee!
Final Words
Understanding airline carry on size limits is one of the most important parts of air travel preparation. Exceeding the maximum dimensions can lead to pricey overage fees and having to check your bag at the last minute. By knowing the standard 22″ x 14″ x 9″ limit and policies of your airline, measuring your luggage carefully, and following savvy packing tips, you can avoid these headaches.
