United Airlines checked bag fees can change based on where you are flying, when you bought the ticket, your fare, and when you pay. A bag that is free on one itinerary may cost $50 or more on another, so the safest approach is to check your reservation before packing.
Quick Answer
On many United Economy trips within the U.S., Canada, Mexico, and Latin America, a standard first checked bag costs $45 when prepaid more than 24 hours before departure or $50 later. The second is $55 prepaid or $60 later. Your exact price depends on the route, fare, ticket date, status, and card benefits.
Key Takeaways
- Common 2026 fees on many short-haul United routes are $45 for the first bag and $55 for the second when prepaid more than 24 hours before departure.
- Paying within 24 hours of departure or at the airport commonly raises those charges to $50 and $60.
- A standard checked bag can measure up to 62 total linear inches and normally weigh up to 50 pounds in Economy.
- Extra-bag, overweight, and oversized charges can apply to the same bag at the same time.
- Premium cabins, MileagePlus Premier status, eligible military travel, and certain United credit cards may include free checked bags.
- Always use United’s official calculator because international allowances, codeshare rules, and destination limits vary.
United Airlines Checked Bag Fees at a Glance
United does not use one baggage price for every flight. The figures below are common rates for many Economy tickets purchased on or after April 3, 2026, for travel within or between the United States, Canada, Mexico, and much of Latin America. Prices are generally charged in each direction.
At a Glance
| First Checked Bag | Commonly $45 when prepaid more than 24 hours before departure or $50 when paid later |
| Second Checked Bag | Commonly $55 when prepaid more than 24 hours before departure or $60 when paid later |
| Third or Additional Bag | Often $200 per bag, subject to route limits and destination restrictions |
| Standard Size | Up to 30 × 20 × 12 inches or 62 total linear inches, including wheels and handles |
| Economy Weight Limit | Normally 50 pounds or 23 kilograms per bag |
| Premium or Premier Limit | Often 70 pounds or 32 kilograms per eligible bag |
Note: These are common prices, not a guarantee for every ticket. Check your exact allowance with the United checked bag fee calculator.
For many 2026 United itineraries, waiting until the airport raises the combined price of the first two checked bags by $10 each way.
How United Calculates Checked Bag Fees
United calculates baggage charges from several parts of the reservation. Looking only at the destination or cabin can produce the wrong estimate.
1. Check the Operating Airline
United’s allowance normally applies to flights operated by United or United Express. A codeshare flight may display a United flight number but be operated by another airline. The operating carrier’s baggage policy may apply, especially when another airline operates the first flight on the ticket.
2. Check the Route and Fare
Domestic, short-haul international, transatlantic, transpacific, and other international markets can have different allowances. Basic Economy or another restricted fare may also have different checked-bag and carry-on rules from standard Economy.
3. Check the Ticket-Purchase Date
United sometimes changes fees based on when a ticket was issued. Two people on the same flight can therefore see different baggage prices if they bought their tickets under different fee schedules.
4. Add Status, Cabin, and Card Benefits
United First, United Business, United Polaris business class, MileagePlus Premier status, eligible military travel, and qualifying United credit cards can reduce or eliminate standard bag fees.
5. Measure and Weigh Every Bag
Measure the outside of the packed bag, including handles, pockets, and wheels. Then weigh it with a reliable luggage scale. Charges for an extra bag, excess weight, and excess size may be added separately.
Pro Tip: Calculate the baggage charge while comparing tickets, not after booking. A fare that costs slightly more but includes two bags may be cheaper than a lower fare plus round-trip baggage charges.
United Checked Bag Size and Weight Limits
A standard United checked bag may measure up to 30 × 20 × 12 inches, or 62 total linear inches. Linear size is calculated by adding length, width, and height. Handles and wheels count toward the measurement.
The standard weight limit is normally:
- United Economy: 50 pounds or 23 kilograms per bag.
- United Premium Plus: commonly 50 pounds or 23 kilograms unless another benefit applies.
- United First, United Business, and United Polaris business class: commonly 70 pounds or 32 kilograms per eligible bag.
- MileagePlus Premier members: eligible complimentary bags can generally weigh up to 70 pounds or 32 kilograms.
Overweight Bag Charges
On many United routes, a bag weighing 51–70 pounds may receive an additional charge of about $100. A bag weighing 71–100 pounds may receive an additional charge of about $200. Some international markets charge different amounts or do not accept bags over 70 pounds.
Oversized Bag Charges
A bag measuring 63–115 total linear inches is oversized. A common oversized-bag charge is $200 in addition to any standard, extra-bag, or overweight fee. Route-specific prices can be higher.
Warning: United generally does not accept bags weighing more than 100 pounds or measuring more than 115 total linear inches. Some destinations have stricter 70-pound limits and may prohibit oversized or additional bags entirely.
Can United Bag Fees Be Combined?
Yes. United may apply more than one charge to the same bag. For example, a third checked bag that weighs 60 pounds and measures 65 linear inches may receive:
- An additional-bag charge
- An overweight charge
- An oversized charge
This can make repacking, dividing items between travelers, or shipping bulky equipment less expensive than checking the bag.
Ways to Avoid United Airlines Checked Bag Fees
Travelers have several ways to reduce or avoid standard checked-bag charges. Each method has its own eligibility rules.
| Method | How It Works |
| Use Carry-On Luggage | Most eligible fares include one carry-on and one personal item. Check restricted Economy or Basic Economy rules before relying on overhead-bin space. |
| Fly in a Premium Cabin | United First, United Business, and United Polaris business class commonly include two standard checked bags at up to 70 pounds each. |
| Use MileagePlus Premier Benefits | Premier Silver, Gold, Platinum, and 1K members receive complimentary baggage allowances based on status and itinerary. |
| Use an Eligible United Card | Qualifying primary cardmembers and one companion may receive one or two free bags when all benefit conditions are met. |
| Use an Eligible Military Allowance | Qualifying active-duty military travelers may receive free checked bags, with the allowance depending on whether the trip is for official orders or personal travel. |
| Prepay Early | On eligible routes, paying online more than 24 hours before departure can save $5 per standard bag. |
Carry-On and Basic Economy Restrictions
United permits one carry-on bag and one personal item at no extra cost on most domestic and international flights. The carry-on limit is generally 9 × 14 × 22 inches, including handles and wheels.
Some restricted Economy or Basic Economy fares may include only a personal item unless the traveler qualifies for an exception. For qualifying tickets purchased on or after April 3, 2026, bringing an ineligible full-size bag to the gate can result in a higher gate-check charge that starts at $75.
Review United’s current carry-on baggage rules before deciding to travel without a checked bag.
United Credit Card Free-Bag Benefits
Eligible United co-branded cards may include one or two complimentary standard checked bags for the primary cardmember and one companion on the same reservation. The exact allowance depends on the card.
Common eligibility conditions include:
- The primary cardmember’s MileagePlus number must be attached to the reservation.
- The ticket usually must be purchased with the eligible United card.
- The companion must travel on the same reservation.
- The flight must be operated by United or United Express.
- Authorized users normally do not receive the benefit when traveling without the primary cardmember.
- Oversized, overweight, and additional-bag charges can still apply.
Review the official United cardmember baggage terms before booking.
United Premier Member Checked Bag Allowances
MileagePlus Premier members receive complimentary checked bags in Economy. Eligible bags can generally weigh up to 70 pounds each.
| Premier Level | Typical Economy Allowance |
| Premier Silver | 1 complimentary checked bag weighing up to 70 pounds |
| Premier Gold | 2 complimentary checked bags weighing up to 70 pounds each; three may apply in select international markets |
| Premier Platinum | 3 complimentary checked bags weighing up to 70 pounds each |
| Premier 1K | 3 complimentary checked bags weighing up to 70 pounds each |
The Premier allowance may extend to as many as nine companions traveling on the same eligible reservation. Group reservations, partner-operated flights, destination limits, and baggage embargoes can change the benefit.
Premier members may also receive priority check-in and priority baggage handling. Priority handling can help bags reach baggage claim earlier, but it does not guarantee that a bag will be the first one delivered.
United Checked Bag Fees for International Flights
International baggage allowances vary much more than domestic charges. The fare, cabin, destination, departure country, ticket date, and operating carrier can all affect whether the first or second checked bag is free.
Do not assume that every Economy ticket to Europe, Asia, or another long-haul destination includes a checked bag. For example, some Basic Economy itineraries include one checked bag, while other restricted international fares charge for the first bag.
Certain destinations also impose limits during busy travel periods. These rules may:
- Limit the total number of bags per passenger
- Prohibit boxes or oversized bags
- Set a maximum weight of 70 pounds
- Stop United from accepting extra bags
- Apply only during specific seasonal travel dates
Review United’s international checked bag limits and calculate the allowance for both the outbound and return journeys.
Tips for Packing to Avoid Excess Baggage Fees
A luggage scale and a tape measure can prevent a costly surprise. Complete the check after packing because expanding a suitcase or filling its outside pockets can push it above the 62-inch limit.
Weigh the Packed Bag
Aim for 47–48 pounds instead of exactly 50. Home and airport scales can differ slightly, and small items added at the last minute may push the bag over the limit.
Measure Wheels and Handles
Measure the longest outside dimensions of the packed bag. Add the length, width, and height together. A 31 × 20 × 12-inch suitcase totals 63 linear inches and may be treated as oversized.
Wear Heavy Items
Wear boots, a jacket, and other bulky clothing during the trip when practical. Keep essential medication, identification, keys, electronics, valuables, and one change of clothing in your carry-on or personal item.
Divide Weight Between Bags
When two travelers each have a bag allowance, spreading the contents evenly may cost less than paying an overweight charge on one suitcase. Confirm that both travelers are eligible for the allowance before repacking.
Compare Shipping Costs
Shipping bulky or heavy equipment may be cheaper than paying combined extra-bag, overweight, and oversized charges. Include pickup, insurance, delivery time, and return shipping in the comparison.
Sports Equipment and Special Items
Most sports equipment counts toward the checked-bag allowance. Standard, extra-bag, overweight, or special-item charges may apply depending on the equipment and route.
Golf clubs should be packed in a protective case, with removable club heads secured and loose items prevented from moving. Travelers carrying clubs can also compare the features of the best golf travel bags before selecting a case.
Strollers, wheelchairs, mobility devices, musical instruments, surfboards, skis, firearms, batteries, and other special items have separate handling or safety rules. Check United’s special-item policy instead of assuming the normal suitcase rules apply.
How United Compares with American and Delta
United’s current short-haul Economy charges are broadly similar to those of American Airlines and Delta Air Lines. All three carriers use route, fare, status, cabin, and card benefits to calculate the final price.
| Airline | Common First Bag | Common Second Bag |
| United | $45 prepaid or $50 later | $55 prepaid or $60 later |
| American Main Cabin | $45 online or $50 at the airport on many routes | $55 online or $60 at the airport on many routes |
| Delta Main | Commonly $45 on eligible domestic routes | Commonly $55 on eligible domestic routes |
Basic Economy charges and online discounts can change the comparison. Confirm current prices through the American Airlines optional-fee page and the Delta baggage calculator and policy page.
