Traveling with a carry-on? Here's what you need to know upfront:
- Size & Weight: U.S. airlines allow carry-ons up to 22×14×9 inches, often without weight checks. International carriers, especially budget ones, may have stricter size and weight limits (15–22 lbs). Always check your airline’s policy.
- Prohibited Items: Liquids over 3.4 oz, sharp objects, flammables, and weapons are banned globally. Some countries, like Japan or the UAE, have unique restrictions (e.g., medications, religious materials).
- Packing Tips: Use compression bags, roll clothes, and pack heavy items at the bottom. Keep electronics and liquids accessible for security checks.
Quick Tip: Double-check your airline’s rules before traveling to avoid surprises at the gate.
MUST-KNOW Carry-on and Personal Item Rules for Flying
Size and Weight Rules
Take Ryanair as an example: even compressed bags can sometimes exceed their strict limits.
Size Limits
For most U.S. airlines, carry-ons must fit within 22×14×9 inches. International airlines can differ, with budget carriers often imposing stricter size requirements.
Weight Limits
In the U.S., carry-ons are rarely weighed. However, many international airlines enforce weight limits between 15–22 pounds, either at check-in or at the gate. To avoid last-minute surprises, it’s smart to check your bag’s weight before heading to the airport.
Staying Within the Rules
- Use a portable scale to confirm your bag’s weight and dimensions after packing.
- If you’re using compression bags like Titantrek's Atlas Vault to save space, keep in mind that budget airlines might still measure the compressed size [1].
Policies can change, so always double-check your airline’s rules. Gate agents often enforce limits more strictly than check-in staff.
Banned Items List
Once you've confirmed your bag fits the size requirements, double-check its contents. Carry-on restrictions differ by region, so it's important to know what you can and can't bring. Below are general global rules, followed by country-specific regulations for added clarity.
Global Restrictions
Most airlines and security agencies around the world prohibit the following items in carry-on luggage:
- Liquids exceeding 3.4 oz (100 mL)
- Sharp objects like knives or scissors with blades longer than 4 inches
- Flammable materials
- Explosives or devices that can start fires
- Weapons and ammunition
- Toxic substances
- Compressed gases
Country-Specific Rules
While the core restrictions are similar worldwide, some countries have additional rules:
- Japan: Strict limitations on bringing certain medications.
- UAE: Prohibits carrying religious materials from other faiths.
- UK: E-cigarettes must be packed in carry-on bags.
- Australia: No powders exceeding 12 oz (350 mL).
- USA: Requires liquids to be stored in clear, resealable bags.
Quick Reference Guide
Use this checklist to ensure your carry-on meets the rules:

- No tools or sharp objects longer than 4 inches
