U.S. and Canada Checked Luggage

• As of Jan. 14, 2010, the checked luggage fees for economy or economy award travel within the U.S. and Canada are $25 for the first bag, $35 for the second. Fees are per person, for a single direction of travel.
  
  Travelers may be subject to additional fees if they check more than two bags. United will levy fees on any one bag that weighs more than 50 lbs., any bag that exceeds 62 linear inches and any bag that is considered a special item, such as surfboards or scuba equipment.
  
  

International Checked Baggage

• On all economy or economy award tickets for international travel to Europe, the Caribbean and Mexico purchased on or after Sept. 30, 2009, the first checked bag is free, and the second is $50. To all other international destinations, the first two checked bags are free. For travel completely within Asia, there is no limit on the number of checked bags permitted.
  
  For all international flights for economy travelers, excluding Asia, bags over 50 lbs. will be charged extra.
  
  Rules vary for United Premiere, business, first class and other special travelers.
  
  

Flights within Asia

• If you are traveling only within Asia, no limit or fees are imposed on the number of checked bags permitted. However, there are restrictions on the size of each bag and the combined weight of all bags for each passenger, including carry-on.
  
  Your luggage weights must fall within the following limits: economy, 44 lbs.; business, 66 lbs.; and first class, 88 lbs.
  
  If you are active U.S. military personnel or dependents with ID and traveling on orders, you may bring any number of duffel bags, sea bags or B-4 bags up to a total maximum weight of 140 pounds.
  
  For all travelers in Asia, checked bags must be no bigger than 115 linear inches and carry-ons must be no bigger than 45 linear inches.
  
  

Carry-on baggage

• For travel on any United flight, both domestic and international, you may carry on one piece of luggage and one personal item such as a purse, briefcase or laptop computer.
  
  Your carry-on bag must fit under the seat in front of you or in the overhead bin, be a maximum of 9 by 14 by 22 inches or 45 linear inches, and you have to be willing to check it if there is not enough space for it in the main cabin.
  
  

Oversized Items

• Any oversize, overweight and excess piece of luggage may be assessed a fee. Note that any checked bag with a single dimension more than 62 inches will not be accepted.
  
  Also, be aware that any checked bag that is more than 115 linear inches will not be accepted. Note that oversized baggage charges are applied in addition to any other charges that may be assessed for overweight or excess baggage. Travelers can only pay fees for oversized baggage at the airport check-in counter, never online.
