What can you bring in carry-on luggage to the U.S.? A to Z guide

Traveling or immigrating to the United States is a dream for many Vietnamese, but preparing your carry-on luggage in compliance with regulations is an important factor to ensure a smooth journey. Carry-on baggage rules in the U.S. are strictly regulated by the Transportation Security Administration (TSA) and the airlines. This article provides information on what items are allowed in carry-on luggage when traveling to the U.S.

General regulations for carry-on luggage when flying to the U.S

Carry-on luggage refers to the items you bring into the passenger cabin of the aircraft. According to TSA guidelines and major airlines operating in Vietnam (such as Vietnam Airlines, United Airlines, or Delta), carry-on luggage must comply with the following standards:

  • Size: Generally no larger than 56 x 36 x 23 cm (including handles and wheels). Some airlines allow an additional small personal item (such as a handbag or laptop backpack) with maximum dimensions of around 40 x 30 x 15 cm.

  • Quantity: Most airlines permit 1 piece of carry-on luggage plus 1 personal item. Business class or first class passengers may be allowed additional carry-on baggage.

  • Weight: Typically limited to 7–10 kg, depending on the airline. Low-cost carriers such as Spirit Airlines may enforce stricter checks.

Items allowed in carry-on luggage

Based on information from TSA and other reliable sources, here is a list of items you can bring in your carry-on luggage when flying to the United States:

Documents and personal belongings

  • Passport, visa, boarding pass, credit cards, cash (it is recommended not to carry more than USD 10,000 to avoid customs declaration).

  • Laptop, phone, tablet, headphones, power bank (capacity under 100Wh; some airlines allow up to 160Wh with prior approval).

  • Books, notebooks, pens, and small office supplies.

Personal care items

  • Liquids, gels, and aerosols (such as toothpaste, hand sanitizer, shampoo) must be in containers of less than 100ml and placed in a transparent plastic bag (maximum capacity of 1 liter). Each passenger is allowed only 1 such bag.

  • Solid cosmetics (lipstick, foundation, eyeliner) are not subject to volume restrictions.

Food

  • Dry food such as biscuits, snacks, and dried fruit is allowed.

  • Fresh food (such as fruits and vegetables) is generally prohibited due to U.S. Customs and Border Protection (CBP) quarantine regulations. For example: jackfruit, durian, and other fresh fruits from Vietnam are not permitted.

  • Prepared food (such as bánh chưng or bánh tét) may be brought if tightly packaged, but must be declared to CBP upon entry. Recent posts on X show that passengers have been fined for failing to declare food brought from Vietnam.

  • Baby food (formula, puree) is permitted in reasonable quantities but must go through security screening.

Electronics and personal devices

  • Cameras, camcorders, and foldable tripods.

  • Personal items such as combs, mirrors, tissues, and face masks.

Airport security screening procedures

When flying to the U.S., you will go through strict security checks both at international airports (such as Tan Son Nhat or Noi Bai) and upon arrival in the U.S. Key points to note:

  • Carry-on baggage screening: All luggage will be scanned by X-ray machines. If any unclear items are detected, you may be asked to open your bag for inspection.

  • Liquid screening: Plastic bags containing liquids must be removed from carry-on luggage and placed separately on the screening tray.

  • Electronics screening: Laptops and tablets must be taken out of their cases and placed separately on trays for scanning.

  • U.S. customs declaration: Upon entry, you must declare all food, cash (over USD 10,000), and high-value items. CBP may confiscate items or impose fines if you fail to comply.

Tips for preparing your carry-on luggage when traveling to the U.S

  1. Check airline regulations: Each airline has its own rules regarding size and weight limits. For example, Vietnam Airlines allows 7kg, while American Airlines may permit up to 10kg.

  2. Pack light and efficiently: Bring only essential items to avoid exceeding weight or size restrictions.

  3. Back up important documents: Keep digital copies of your passport, visa, and invitation letter (if applicable) on your phone or email.

  4. Prepare for customs inspection: Review the U.S. CBP Declaration Form (Form 6059B) carefully before arrival to avoid mistakes.

  5. Bring light snacks: Long-haul flights (often over 15 hours from Vietnam) can leave you hungry, so carry suitable snacks like crackers or chips for the journey.
