Complete Guide To United Airlines Baggage Allowance 2023

About to fly with United Airlines? The airline has a fairly standard baggage allowance policy in general. However, their baggage policy is similar to other top U.S airlines. Each travel class also has its benefits and restrictions on baggage allowance.

This article will guide you through everything about the baggage allowances, costs, limitations, and charges on United Airlines.

Carry-on Baggage on United Airlines

Most passengers can bring a carry-on, a personal item, and other special items on board. However, there are certain exceptions.

The dimensions for each carry-on should not be above 22 x 35 x 56 centimeters (9 x 14 x 22 inches). This measurement includes the bag handles and wheels. Also, the carry-on must enter inside the overhead cabin.

A personal item, like a purse, handbag, or laptop bag, is meant to fit under the seat in your front. Also, the dimensions should not be above 22 x 25 x 43 centimeters (9 x 10 x 17 inches).

Other special items allowed on board include:

  • A diaper bag.
  • An umbrella.
  • A jacket.
  • Reading material.
  • A camera.
  • Devices for mobility (like crutches, foldable wheelchairs, canes, a medical device for prescription medications, or a sizable oxygen concentrator).
  • Child safety seat (FAA-approved).
  • A breast pump.
  • Food/snacks/goods bought at the airport.
  • A pet carrier (onboard pets incur charges).


Passengers flying basic economy class are exempted from the above carry-on policy. A basic economy boarding pass allows only one personal item onboard.

If you report at the airport gate with a full-sized carry-on, you must check it. Also, it will incur a $25 gate handling fee with the relevant checked bag price. Credit cards are accepted at the gate to simplify the payment process.

However, travellers flying basic economy class where any of the following applies are not among the exceptions:

  • Passengers travelling on trans-Atlantic flights between the United States, Mexico, and Central America, including El Salvador, Panama, and South America, are exempted.
  • Passengers travelling on trans-Pacific flights to or from the United States are exempted.
  • Guests or Members of MileagePlus® Premier® travelling on the same booking.

  1. Hello,
    I perused the baggage limits and restrictions, but did not see our rather unique situation. We are traveling from Rochester to Newark, NJ on economy tickets, but will take a United flight on business class tickets to Venice, Italy. Our return flights are all business class.
    Will we be able to bypass the economy class restrictions for weight and number of items on board? I certainly hope so!
    Thank you in advance for your help.
