Traveling internationally in 2025? Here's what you need to know about carry-on rules:
- Standard Size and Weight: Most airlines stick to 22 x 14 x 9 inches and 15–26 pounds. Always include wheels and handles in your measurements.
- Liquid Restrictions: Follow the 3-1-1 rule - liquids in 3.4 oz containers, all fitting in one quart-sized clear bag.
- Electronics: Laptops must be removable for TSA checks, and spare batteries are allowed under 100 watt-hours.
- Regional Differences: European and Asian airlines enforce stricter weight limits, while U.S. carriers focus more on size.
- Packing Smart: Use tools like vacuum compression backpacks to maximize space and stay organized.
Quick Tip: Always double-check your airline’s specific carry-on policies before flying to avoid fees and delays.
Size and Weight Limits by Airline
Basic Size and Weight Rules
Most international airlines follow similar standards for carry-on size limits. Here’s what you can typically expect:
- Combined dimensions: 45 inches (length + width + height)
- Individual dimensions: 22 x 14 x 9 inches
- Weight limits: Usually between 15 and 26 pounds
These measurements include everything - wheels, handles, and external pockets. Using compression backpacks, like those from Titantrek, can help you maximize space within these restrictions.
Airline Rules Comparison Chart
While many airlines stick close to the standard, there are slight differences. Here’s a quick comparison of current rules:
| Airline | Maximum Dimensions (inches) | Weight Limit (lbs) | Personal Item Allowed |
|---|---|---|---|
| American Airlines | 22 x 14 x 9 | 22 | Yes (18 x 14 x 8) |
| Delta Air Lines | 22 x 14 x 9 | 25 | Yes (17 x 13 x 8) |
| United Airlines | 22 x 14 x 9 | 26 | Yes (17 x 10 x 9) |
| Emirates | 22 x 15 x 8 | 15 | Yes (18 x 14 x 7) |
| Lufthansa | 21.7 x 15.7 x 9 | 17.6 | Yes (15.7 x 11.8 x 3.9) |

| British Airways | 22 x 18 x 10 | 26 | Yes (16 x 12 x 6) |
Key regional differences:
- European airlines often have stricter weight limits, typically between 15 and 17 pounds.
- Asian carriers are known for strictly enforcing both size and weight rules.
- Middle Eastern airlines may allow larger dimensions but often have lower weight allowances.
- U.S. airlines tend to focus more on size rather than weight for carry-ons.
Keep in mind that ticket class can affect these allowances, so it’s always a good idea to double-check your airline’s current policies.
Rules for Liquids, Electronics, and Special Items
Liquid Limits and 3-1-1 Rule
Each liquid you bring must be in containers of 3.4 oz (100 mL) or less. All containers should fit into a single clear, quart-sized bag, and each passenger is allowed only one bag. To make security checks easier, use a pocket in your bag that allows quick access to this clear bag.
Electronics and Battery Rules
Security checks also focus on electronics. Here are some key guidelines:
| Device Type | Carry-on Guidelines | Additional Considerations |
|---|---|---|
| Laptops/Tablets | Must be easily removable | May need to power on during screening |
| Spare Batteries | Carry in your carry-on | Usually limited to under 100 watt-hours |
| Power Banks | Allowed if they meet safety standards | Must comply with watt-hour restrictions |
| Smartphones | Can stay in your bag | Keeping them charged is a good idea |
| Camera Equipment | Permitted | May need to be taken out for screening |
Always ensure battery-powered devices are charged in case they're inspected during screening.
Medical Items and Exceptions
Liquid medications are not subject to the 3-1-1 rule, but they must be declared and kept in their original, labeled packaging. Essential medical equipment like insulin pumps or CPAP machines may need separate screening. Bring supporting documents and prescription labels, and pack these items in a clear bag for easy access.
Having these items well-organized can make the entire security process smoother.

How to Pack Within Carry-On Limits
Packing smartly helps you make the most of your carry-on space while staying within travel regulations. This can save you time, hassle, and those annoying extra fees.
Choosing the Right Carry-On Bag
Pick a carry-on bag that complies with TSA guidelines to avoid potential issues at the airport. A good example is the Titantrek Atlas Vault. It offers vacuum compression to save space, waterproof materials for durability, and even a dedicated 17" laptop compartment for convenience [1].
Once you've got the right bag, it's time to make every inch count with efficient packing techniques.
Tips for Maximizing Space
Packing efficiently isn't just about cramming things in - it’s about using smart techniques to fit more into your carry-on. Here are a few strategies:
| Technique | How It Works | Why It Helps |
|---|---|---|
| Compression Technology | Use vacuum compression systems | Cuts clothing volume by up to 50% |
| Compartmentalization | Rely on dedicated sections | Keeps items organized and tidy |
| Roll vs. Fold | Roll clothes instead of folding | Saves space and reduces wrinkles |
| Strategic Layering | Place heavy items at the bottom | Stabilizes the bag and protects fragile items |
"Arrived in reasonable time, seems of very good quality of materials, lots of compartments for all eventualities, very well organized, vacuum system works perfectly and the pump is powerful" [1].
Once your bag is packed, organizing it for security checks will make your airport experience smoother.
Organizing for Security Checks
A well-organized bag can speed up security checks and protect your belongings. Here’s how to prepare:
- Electronics: Keep laptops and other devices in easy-to-reach compartments.
- Valuables: Use anti-theft pockets for important items like wallets or passports.
- Liquids: Store them in external pockets for quick removal.
- Travel Documents: Keep tickets and IDs in a dedicated section for easy access.
"Great product! A lot of space and separations for everything. Some pockets are waterproof. Great for traveling, fits a lot in air vacuum pocket. Really recommend. Also fast delivery. Even on Christmas time was delivered in 1 week to Spain" [1].
Common Carry-On Mistakes to Avoid
Navigating international carry-on rules can be tricky. Always check your airline's policies and the regulations for your destination to steer clear of any issues.
Special Item Rules
Certain items - like musical instruments, duty-free liquids, baby gear, or sports equipment - often have specific rules. Airlines may have unique requirements for these, so it's worth reviewing their guidelines before packing. Using a well-designed carry-on, such as the Titantrek Atlas Vault Backpack with vacuum compression, can help you stay organized and within size limits.
Regional regulations can also impact what you can bring, so double-check those details as well.
Regional Differences
Carry-on policies aren't the same everywhere. Make sure to verify both your airline's and your destination's rules to avoid surprises.
Dealing with Oversized Bags
If your carry-on is too big or heavy, it's best to address the issue before you arrive at the airport. Measure and weigh your bag in advance. If it's over the limit, consider checking it at the gate, redistributing items among your companions, or repacking to make it fit. A little preparation can save you from inconvenient delays during your trip.
Summary and Tips
Pre-Flight Checklist
Before heading to the airport, make sure your carry-on meets these key requirements:
- Measure and weigh your bag: Confirm it fits your airline's size and weight limits.
- Check airline policies: Review your carrier's latest rules, especially if you're flying with multiple airlines.
- Pack liquids properly: All liquids should be in containers no larger than 3.4 oz (100 ml) and placed in a clear, quart-sized bag.
- Prepare electronics: Keep laptops and other large devices easy to access for security checks.
