United Airlines Carry-On Baggage Policy Explained

Understanding the United Airlines carry-on baggage policy before your trip can help you avoid unnecessary baggage fees and boarding issues. On most domestic and international flights, United Airlines allows passengers to bring one carry-on bag and one personal item free of charge. However, passengers traveling on Basic Economy fares have different baggage restrictions.

Carry-On Bag Size

Your carry-on bag must meet the following size requirements:

• Maximum dimensions: 9 in x 14 in x 22 in (23 cm x 35 cm x 56 cm)
• Measurements include wheels, handles, and side pockets
• The bag must fit securely in the overhead bin

Any bag exceeding these dimensions may need to be checked at the airport.

Carry-On Weight Rules

United Airlines does not have a standard carry-on weight limit for most flights. However, passengers must be able to:

• Lift the bag into the overhead bin
• Store it safely inside the aircraft
• Follow airport security requirements

For a comfortable travel experience, keep your carry-on bag lightweight and easy to handle.

Personal Item Allowance

In addition to your carry-on bag (where permitted), you may bring one personal item that fits under the seat in front of you.

Examples of personal items include:

• Small backpack
• Laptop bag
• Purse
• Briefcase

Your personal item must be small enough to fit completely under the seat in front of you.

Basic Economy Carry-On Rules

Passengers traveling on Basic Economy tickets can generally bring only one personal item. A standard carry-on bag is not included unless you qualify under one of the following exceptions.

You can bring one free carry-on bag if you are:

• A MileagePlus Premier® member
• Traveling with a MileagePlus Premier member
• The primary cardholder of an eligible MileagePlus® credit card
• A Star Alliance Gold member

Important: The United Gateway^SM Card and the United MileagePlus® Select Card do not qualify for a free carry-on bag when traveling on a Basic Economy ticket.

Additional Items You Can Bring for Free

Besides your allowed carry-on bag and personal item, United Airlines also permits several items at no additional cost, including:

• Jacket or coat
• Umbrella
• Reading materials
• Food or beverages purchased at the airport
• Mobility devices, such as wheelchairs, canes, or crutches
• Car seat, child safety harness, or stroller
• Diaper bag and breast pump (even if you are not traveling with your child)

Important Tip:

You cannot bring an extra small purse or handbag in addition to your personal item and carry-on bag. Make sure all your belongings fit within the permitted baggage allowance to avoid delays or additional charges at the airport.

Gate-Checked Bags

Your carry-on bag may be gate-checked if:

• Overhead bin space is full
• Your bag exceeds the size limit
• You exceed the carry-on baggage allowance
