United Airline Baggage Policy​: Rules, Fees & Limits

United Airlines baggage policy allows passengers to bring carry-on and checked luggage based on their ticket class, route, and cabin class. Most passengers can bring a personal item and one carry-on bag, but Basic Economy passengers may face limitations. Allowances for checked luggage and extra fees will depend on the itinerary and available travel perks. Knowing this in advance will help you pack properly and avoid surprises from baggage fees. This guide covers United Airlines baggage policy, including carry-on rules, checked luggage allowance, weight limits, and extra baggage fees.

What is United Airlines Baggage Policy?

The United Airlines baggage policy outlines the rules for carry-on luggage, personal items, checked baggage, baggage fees, and size and weight restrictions for passengers traveling with United Airlines. The baggage allowance varies by route, ticket type, cabin class, and frequent-flyer membership status.

Most passengers can bring one personal item and one carry-on bag, although Basic Economy tickets may have additional carry-on restrictions on certain routes. Checked baggage allowances and fees depend on the itinerary and fare conditions. Passengers should also follow the airline’s size and weight limits to avoid additional charges at the airport.

United Airlines Baggage Allowance at a Glance

When planning your travel, it is wise to learn about the two different kinds of luggage you can carry on United Airlines. Your luggage will be either carry-on or checked, depending on where you place it when checking in at the airport.

How much luggage you can have depends on your ticket. Below is an overview.

Baggage Type	General Allowance
Personal item	1 item per passenger
Carry-on bag	Generally 1 bag, depending on fare and route
Checked baggage	Depends on the ticket and destination
Additional baggage	Fees may apply

These are general guidelines rather than a guaranteed allowance for every flight. Always check the baggage details associated with your booking before departure.

United Airlines Carry-On Baggage Policy

Not sure if you can carry both the suitcase and the backpack onboard? Generally, passengers can carry one carry-on bag and one personal item onboard. But there are certain requirements imposed by United Airlines for passengers who travel under Basic Economy class on certain routes.

Under the United Airlines baggage policy carry-on bags​ must fit in the overhead compartment, while personal items should fit under the seat in front of you. Choosing the right bag size before leaving home can help you avoid last-minute baggage issues at the airport.

Carry-On Allowance by Fare Type

Carry-on allowances vary by fare paid and destination. The table below provides an outline of the general policy for different United Airlines cabin and fare classes.

Class / Fare Type	Carry-On Allowance
Basic Economy — domestic and certain short-haul international routes	1 personal item only
Basic Economy — eligible long-haul international routes	1 carry-on bag + 1 personal item
United Economy	1 carry-on bag + 1 personal item
Economy Plus	1 carry-on bag + 1 personal item
Premium Plus	1 carry-on bag + 1 personal item
United Business / First / Polaris	1 carry-on bag + 1 personal item

Note: However, exceptions do exist for some selected MileagePlus members and credit card holders. Please note that different Basic Economy policies are in place and that you should check your individual allowance before packing.

Carry-On Size Limits and Personal Item Rules

United Airlines requires passengers to ensure their cabin luggage fits safely inside the aircraft. If your luggage exceeds the prescribed size, you’ll have to check it, and you may be charged.

Bag Type	Maximum Dimensions
Carry-on bag	22 × 14 × 9 inches (56 × 35 × 23 cm)
Personal item	17 × 10 × 9 inches (43 × 25 × 23 cm)

Handles and wheels are included in measurements. A personal item includes a small backpack, purse, laptop bag, or other small bag that fits under the seat.

There is no fixed weight limit for carry-on bags on United Airlines for all flights, but customers should be able to handle their bags appropriately.

United Airlines Checked Baggage Policy 

When planning a long-distance trip or taking more than one cabin bag, knowing United Airlines checked baggage policy will help you understand how many suitcases you can check and any associated fees.

United Airlines uses the concept of pieces for checked baggage. In essence, your luggage allowance is determined by the number of pieces that you can take, and their maximum dimensions and weight. You cannot split an allowance for two pieces of luggage into three suitcases.

Checked Baggage Allowance by Cabin Class

The quantity of baggage checked will depend on the route, rate, cabin class, and benefits that may apply to your travel. The following is a table of the weight restrictions for each piece of luggage.

Cabin Class / Membership	Typical Maximum Weight Per Bag
United Economy	50 lbs (23 kg)
United Premium Plus	Generally 50 lbs (23 kg)
United Business	Generally 70 lbs (32 kg)
United First	Generally 70 lbs (32 kg)
United Polaris	Generally 70 lbs (32 kg)
Eligible Premier members	May qualify for higher weight limits or additional bags
Star Alliance Gold members	Depends on cabin class and applicable baggage rules

Remember that the maximum weight of each bag does not necessarily match the number of bags provided free of charge. Consult your reservation for details

United Airlines Checked Baggage Size Limit

Weight is just one of the many considerations in packing your luggage in advance. Your luggage must also meet the dimensions required by United Airlines.

Checked Baggage Requirement	Standard Limit
Maximum total linear dimensions	62 inches (158 cm)
Measurement method	Length + width + height
Typical Economy weight limit	50 lbs (23 kg) per bag
Typical premium-cabin weight limit	70 lbs (32 kg) per bag

For example, a suitcase measuring 30 × 20 × 12 inches totals 62 linear inches. Remember to include the wheels and handles when measuring your luggage.

United Airline Baggage Policy​ for Special Items

Carrying sporting equipment, musical instruments, or baby equipment requires extra consideration. Some items may qualify as regular luggage, but others may require special packing or handling or incur an extra charge.

For instance, golf clubs or ski gear may be subject to specific sporting equipment policies. Small musical instruments that fit in the passenger cabin may be acceptable if they meet specific criteria, but larger ones may need to be transported differently. Passengers with babies should be aware of the regulations for strollers, car seats, etc. Medical equipment and mobility devices may have their own set of regulations. If you are transporting an odd-shaped or bulky object, it is recommended that you familiarize yourself with United Airlines regulations on such cargo prior to going to the airport.

Baggage Policy for United Airlines MileagePlus Members

United Airlines MileagePlus members can take advantage of baggage perks based on their Premier membership tier and route of travel. These perks can include free checked bags, allowing frequent flyers to avoid extra baggage fees. The higher the tier, the greater the baggage allowance, although this will vary according to the route flown.

MileagePlus Status	Free Checked Bags (Domestic)	Free Checked Bag (International)
General Member (No Status)	Depends on ticket and route	Depends on ticket and route
Premier Silver	Additional baggage benefits may apply	Additional baggage benefits may apply
Premier Gold	Additional baggage benefits may apply	Additional baggage benefits may apply
Premier Platinum	Additional baggage benefits may apply	Additional baggage benefits may apply
Premier 1K	Additional baggage benefits may apply	Additional baggage benefits may apply

These benefits could also apply to eligible companions flying on the same reservation, depending on the policies of United Airlines. Because baggage allowance policies vary by cabin class, destination, and ticket type, MileagePlus members should review their reservation before their flight.

Extra Baggage Weight Limits and Restrictions

What is the weight of a suitcase above which you will incur extra fees? The United Airlines baggage policy weight​ varies by cabin class, travel route, and applicable baggage benefits.

In accordance with the United Airlines baggage policy weight limits, it is the limit for each individual bag that you are checking rather than the aggregate weight of your entire luggage that matters. If your bag exceeds its limit, even if the others are below theirs, you may have to pay an overweight baggage fee. So, an Economy passenger who has a 23 kg limit per bag might be charged extra for a suitcase weighing 27 kg. Premium cabin customers have higher allowances per suitcase.

Before checking in, weigh your suitcase at home to ensure it doesn’t exceed the limit. If you feel it is close to the limit, you can try arranging your luggage into different allowed suitcases.

Checked Baggage Fees and Extra Charges

While international baggage policies can differ from domestic ones, it’s not fair to expect the same policy to apply to all travel. In case of an international flight, the number of checked baggage included in the ticket will depend on the traveler’s destination, fare purchased, cabin class, and relevant benefits.

Some international Economy fares may include a free checked bag, while others may charge a fee for the first checked bag. On premium cabin flights, you may get a better allowance, but you’ll need to verify it. When booking an international flight with connecting flights, make sure you know which airline operates each leg of the journey. This is because there may be different baggage conditions in case of partner airlines. Check your itinerary and United Airlines’ baggage guidelines before traveling, especially if you’re carrying multiple suitcases.

Carry-on Baggage Extra Charges

Oversized bags may need to be checked, and applicable checked baggage fees may apply. Standard carry-on baggage must not exceed 22 × 14 × 9 inches (56 × 36 × 23 cm), including wheels and handles. Personal items, such as small backpacks, handbags, or laptop bags, must fit under the seat in front of you. United Airlines does not generally impose a specific weight limit on standard carry-on bags, but passengers must be able to lift and stow their luggage safely. 

How to Avoid Extra Baggage Fees on United Airlines

By planning ahead, you can save a few dollars on luggage costs. Instead of relying on old baggage guidelines, check the allowance associated with your ticket before you depart. Some helpful tips include:

• Review your ticket: Determine whether your ticket covers a carry-on bag and any checked baggage.
• Review other booking conditions: Along with baggage allowances, check United’s cancellation policy to understand the rules and fees that may apply if your travel plans change.
• Measure your suitcases: Account for wheels and handles to ensure your bags qualify.
• Weigh all bags: Weigh each suitcase instead of estimating the total weight.
• Determine baggage costs in advance: Use the online calculator provided by United Airlines to determine the price.
• Understand your travel perks: Some frequent flyer or credit card statuses might give you extra baggage allowance.
• Pack strategically: Make sure your necessities are easy to access within your personal item.
• Consider your connecting flights: If another company is involved in your travel, check their baggage policy.

Taking these steps should reduce the chance of last-minute packing and unexpected fees.

Rules For Packing Your Checked Baggage

With the baggage allowance rules in mind, pack your luggage before your trip. Some preparations before you leave will help protect your luggage and prevent problems. Here are some packing suggestions that you should take note of.

• Label your luggage: Affix a luggage tag with your name and phone number on your bag. You can also attach a second copy in case the first one falls off.
• Protect your belongings: Make sure your luggage is properly closed by zipping it, so nothing falls out while it’s being handled.
• Protect your valuables: Do not pack your cash, jewelry, documents, or medication in your checked luggage. Keep them in your personal item or in your hand luggage.
• Check your bags in on time: Check in and check your bags well in advance to comply with the air carrier’s deadline.
• Retain your luggage claim tag: Retain your luggage claim tag until you pick up your checked bags at your destination.
• Find out about restricted items: Find out about the restrictions and prohibitions of United Airlines regarding certain items that cannot be taken with you in your checked luggage.

Traveling tip: When you’re packing to head to the airport, make sure that you know the details of your baggage allowance, weight restrictions, and prohibited items before heading off to catch your flight.
