As your departure date approaches, you may be thinking about what to pack and whether or not to check a bag.
Please take a minute to review our carry-on guidelines so that you know before you go and your trip gets off to a smooth start.

To ensure a smooth boarding experience, it’s important to make sure that these items will fit into the overhead bin or under the seat in front of you.

United Carry On Personal items
The maximum dimensions for your personal item, such as a shoulder bag, backpack, laptop bag or another small item, are 9 inches x 10 inches x 17 inches (22 cm x 25 cm x 43 cm).
To determine if a bag will fit onboard, bag sizes will be available in the airport lobby. Once at the gate, any item in excess of the carry-on baggage size or allowance requirements will be checked to your final destination and may be subject to applicable service charges.
Carry-on items that are acceptable to transport in the cabin but are fragile or bulky will be considered cabin-seat baggage. Customers can purchase a ticket for a cabin-seat baggage item so that it may be carried on board and transported in a seat.
The following items are allowed and do not count toward your one bag and one personal item limit:
- Jacket or umbrella
- Reading material

United Liquids, Gels and Aerosols Rules
The Transportation Security Administration (TSA) allows each traveller to carry on liquids, gels and aerosols in containers of 3.4 ounces (100 mL) or less, inside a single quart-size (litre-size) clear, sealable bag.
Passengers travelling internationally into the U.S. and connecting to another flight are allowed to have in their carry-on baggage liquids in excess of 3.4 ounces (100 mL) that were purchased as duty-free merchandise. This only applies to products purchased in duty-free stores, placed in an intact designated secure, tamper-evident bag, and successfully screened and cleared by TSA officers. Scanning may not be effective for liquids in opaque, ceramic, or metallic bottles, or other containers. Liquids that cannot be screened and cleared will not be allowed to remain in carry-on baggage. Customers may choose to place these items into checked baggage or throw them away.
