Carry-on Baggage

  • Allowance: United Airlines allows one carry-on bag and one personal item per passenger. The carry-on bag must fit in the overhead bin, while the personal item should fit under the seat in front of you.
  • Size and Weight Limits: The maximum dimensions for a carry-on bag are 22 x 14 x 9 inches (56 x 36 x 23 cm). There is no specific weight limit, but you must be able to lift the bag into the overhead bin unassisted.

Checked Baggage

  • Allowance and Fees: The number of checked bags allowed and the fees associated with them vary depending on your fare class, route, and frequent flyer status. Typically, Economy Class passengers pay for their first and second checked bags, while higher classes may include free checked baggage.
  • Size and Weight Limits: Each checked bag can weigh up to 50 lbs (23 kg) for Economy fares and up to 70 lbs (32 kg) for Premium Economy, Business, and First Class fares. The maximum dimensions for checked baggage are 62 linear inches (158 cm) when adding the length, width, and height.

Additional and Oversized Baggage

  • Extra Baggage Fees: If you exceed the standard allowance, additional fees will apply. The cost varies based on the route and baggage size.

Baggage Protection

Familiarize yourself with the United Airlines baggage policy to avoid any surprises at the airport. Ensure your baggage meets the size and weight limits to prevent additional fees.
