United Airlines Baggage Policy Explained: Size, Weight & Fees

Understanding baggage rules before flying can save you money, time, and unnecessary stress at the airport. The United Airlines baggage policy is structured but varies based on ticket type, route, and frequent-flyer status. This guide explains carry-on and checked baggage rules in simple terms, so you know exactly what to expect before your journey.

Carry-On Baggage Rules

United Airlines allows most passengers to bring one carry-on bag and one personal item on board at no extra charge.

Carry-on size limit

• Maximum dimensions: 9 in x 14 in x 22 in (including handles and wheels)
  
  

• The bag must fit in the overhead bin
  
  

Personal item

• Examples: purse, laptop bag, small backpack
  
  

• Must fit completely under the seat in front of you
  
  

Basic Economy exception

If you booked a Basic Economy ticket, your allowance is more limited:

• Only one personal item is included
  
  

• A full-size carry-on may incur an additional fee unless you are a Premier member or hold a qualifying United credit card
  
  

Checked Baggage Allowance

Checked baggage fees depend on your route, fare type, and loyalty status.

Standard size and weight

• Maximum size: 62 linear inches (length + width + height)
  
  

• Maximum weight: 50 lbs (23 kg) for Economy and Premium Economy
  
  

• Business and First Class passengers are usually allowed heavier bags
  
  

Number of checked bags

• Most Economy travelers can check up to two bags
  
  

• Additional bags beyond the limit will cost extra
  
  

United Airlines Checked Baggage Fees

For most domestic U.S. flights:

• First checked bag: around $35
  
  

• Second checked bag: around $45
  
  

Fees may be lower if you prepay online and higher if you pay at the airport. International routes often follow different pricing rules, so it’s best to check before departure.

Overweight and Oversized Baggage

If your bag exceeds standard limits, extra charges apply.

Overweight bags

• 51–70 lbs: additional fee
  
  

• 71–100 lbs: higher fee and limited acceptance
  
  

Oversized bags

• Bags larger than 62 linear inches are considered oversized
  
  

• Sports equipment and musical instruments may have special handling rules
  
  

Planning ahead and weighing your bag at home can help avoid these charges.

Special Items and Sports Equipment

United allows items such as:

• Golf bags
  
  

• Skis and snowboards
  
  

• Strollers and child safety seats
  
  

Some sports equipment may count as a standard checked bag if it meets size and weight requirements, while others may require extra fees. Always review item-specific rules before packing.

Baggage Allowance for Elite Members and Credit Card Holders

Passengers with Premier status or a United-branded credit card often receive benefits such as:

• One or two free checked bags
  
  

• Priority baggage handling
  
  

• Higher weight limits on certain fares
  
  

These perks can significantly reduce travel costs for frequent flyers.

Tips to Avoid Extra Baggage Fees

• Measure and weigh your bags before leaving home
  
  

• Prepay for checked baggage online
  
  

• Use a carry-on efficiently to avoid checking a bag
  
  

• Take advantage of loyalty or credit card benefits
