If you are unsure about a specific item, use the category guide below to quickly find the exact rule and packing guidance.
Understanding TSA Carry-On Rules
The Transportation Security Administration (TSA) is responsible for screening passengers and baggage at airport security checkpoints in the United States. TSA officers inspect carry-on items using X-ray machines and additional screening methods to identify prohibited or restricted items.
Most everyday belongings are allowed through security, but some items may require additional screening or follow special rules. For example, travelers often check the specific regulations for items such as medications, supplements, or toiletries before packing.
For detailed guidance on one common question, see our guide, Can you bring prescription medication on a plane.
Travelers typically bring three types of baggage through the airport:
Carry-on luggage
This is the main bag placed in the overhead compartment on the aircraft. It must pass through TSA screening at the security checkpoint.
Personal items
These include smaller bags such as purses, laptop bags, or backpacks that fit under the seat in front of you.
Checked luggage
These bags are checked at the airline counter and placed in the aircraft cargo hold. Some items restricted in carry-on bags may still be allowed in checked baggage.
Understanding these differences helps travelers pack correctly and avoid having items removed at security.
Liquids, Toiletries, and the TSA 3-1-1 Rule
One of the most important airport security rules involves liquids and toiletries in carry-on luggage.
The TSA uses the 3-1-1 rule, which means:
- Liquids must be in containers 3.4 ounces (100 ml) or smaller
- All liquid containers must fit in one quart-size clear bag
- Each passenger may bring one liquids bag
This rule applies to common toiletries such as shampoo, toothpaste, lotion, and liquid cosmetics.
If a container is larger than 3.4 ounces, it will usually be removed during screening even if it is partially empty.
This rule applies to common toiletries such as shampoo, toothpaste, lotion, and liquid cosmetics.
Medications and Supplements
Medications are generally permitted in both carry-on and checked luggage, and travelers are encouraged to keep important medications in their carry-on bags.
Prescription medications do not fall under the standard TSA liquids rule in the same way as toiletries. Liquid medications are allowed in quantities larger than 3.4 ounces when medically necessary, although they may require additional screening.
Most pills and tablets are unrestricted and can be packed normally in carry-on luggage.
Travelers often ask about specific medications and supplements. These guides explain the rules in detail:
- Can you bring prescription medication on a plane
- Can you bring sleeping pills on a plane
- Can you bring melatonin on a plane
- Can you bring vitamins on a plane
Keeping medications organized and accessible during screening can help the process move more quickly.
Comfort Items and Personal Accessories
Many travelers bring comfort items on flights, especially for long journeys.
Common examples include:
- Travel blankets
- Neck pillows
- Small accessories such as lap blankets or personal comfort items
These items are generally allowed through airport security as long as they pass standard screening procedures.
For example, blankets are permitted in both carry-on and checked luggage, although they may occasionally be removed for inspection during screening. See our detailed guide: Can you bring a blanket on a plane.
Small accessories such as decorative pins are also usually allowed, though sharp objects may sometimes receive additional inspection. Learn more here: Can you bring pins on a plane.
Items That Are Restricted in Carry-On Bags
While most everyday belongings are allowed on planes, certain items cannot pass through airport security in carry-on luggage.
| Item Type | Carry-On Allowed | Checked Bag Allowed |
|---|---|---|
| Large liquid containers | No | Yes |
| Sharp objects (knives, scissors) | Usually no | Yes |
| Certain tools | Usually no | Yes |
Many restricted items can still travel in checked baggage instead of carry-on luggage.
If a restricted item is discovered during screening, TSA officers may confiscate it or ask the traveler to return to the check-in area to place it in checked luggage.
Checking TSA guidelines before packing helps prevent these situations and keeps the security process moving smoothly.
Tips for Getting Through Airport Security Faster
Preparing your carry-on bag correctly can significantly speed up the airport security process. These simple habits help travelers move through TSA screening more quickly.
| Tip | Why It Helps |
|---|---|
| Pack liquids in a quart-size bag | Makes them easy to remove during screening |
| Separate large electronics | TSA may require laptops or tablets to be screened separately |
| Keep medications accessible | Allows faster inspection if TSA officers need to check them |
| Organize your carry-on bag | Reduces the chance of additional manual screening |
Following these simple packing habits can make airport security faster and less stressful.
