United Airlines checked bag fees

We have not verified this airline's baggage fees against the carrier yet. Rather than guess, we have left it blank — check the airline before you fly.

This page goes deeper on one part of the policy. The full record is at United Airlines Baggage Rules.

United does not print one flat United checked bag fee. It runs every bag through a per itinerary calculator. The price shifts with your route, your fare and the date you bought the ticket.

United’s own checked bags page says to use the calculator. It states plainly that the price depends on where and how you travel. The page also lists three 2026 dates when United checked bag fee pricing moved up.

Fees rose April 3 on domestic flights and short hops to Latin America, Canada, the Caribbean and Mexico. They rose again May 12 on many flights from the United States to Africa, Asia, Europe and South America. A third increase landed July 21 on flights to Japan, Hong Kong, the Philippines and between Asian countries.

What United does publish

United will not hand you a first or second bag dollar figure without a route and a ticket. What it does publish are the size and weight caps. Those caps decide whether a bag needs the calculator, or an overweight surcharge on top of it.

Our United Airlines baggage rules page covers the carry-on and personal item limits that sit behind these bag fees.

ItemLimit United publishes
Checked bag size30 in x 20 in x 12 in (76 x 52 x 30 cm), 62 total linear inches, wheels and handles included
Weight, United Economy and Premium Economy50 lb (23 kg) per bag
Weight, Business, First and Polaris business class70 lb (32 kg) per bag
Weight, Premier Silver, Gold, Platinum and 1K70 lb (32 kg) per bag, even in Economy
Basic Economy gate handling charge25 USD plus the applicable checked bag fee, when a bag is not checked in advance
Mishandled bag delivery to your addressFrom 39.95 USD to 159.95 USD per order

Those figures come straight off United’s optional service charges page. For the exact United checked bag fee on your own trip, the calculator is the only honest source. A printed table would be wrong for someone booking a week later.

Lufthansa and British Airways price the same way, by itinerary rather than a flat grid. Check your own fare’s allowance on our checked baggage weight limit page before assuming a number from memory.

Prepay and the calculator

United’s prepay page confirms you save time at the airport by paying online. On some routes you also get a discount if you prepay more than 24 hours before departure. It does not state the discount amount, since that also rides on route and date.

One thing is settled either way. Prepaying shows you your United checked bag fee before you reach the airport, and it lets you use the bag drop shortcut instead of a line.

Overweight and oversize bags

United weighs every checked bag at the counter. A bag over the cabin’s weight cap, or over the 62 linear inch box, triggers a separate charge on top of the base fee. That surcharge also runs through the same calculator rather than a number United prints anywhere public.

The one number worth memorizing is not a fee. It is your own bag’s weight. A bag that comes in under the cap avoids the surcharge no matter what that surcharge happens to cost on your route.

A digital luggage scale clips onto a handle at home. Reviewers say it pays for itself the first time it catches an overweight bag before an agent does. Check the overweight and oversize baggage fees guide, since the bands vary more than travelers expect.

Who skips the United checked bag fee

MileagePlus status buys a free bag long before it buys anything else. Per United’s own Premier benefits page, Premier Silver gets one free checked bag. Gold gets two, and Platinum and 1K each get three, all up to 70 lb.

Star Alliance Gold status earned on a partner airline carries an extra baggage allowance on United too. A United branded credit card is the other common route. Cardholders typically get a free first bag for themselves and companions, worth checking against our credit cards that cover baggage fees guide before paying at check-in.

Basic Economy and the carry-on squeeze

Basic Economy tickets on most United routes drop the free carry-on. What is left is a personal item only. Show up at the gate with a rolling bag on that fare, and United checks it there and adds the 25 USD gate handling charge on top.

Packing everything into a compliant personal item avoids that charge. A rolling underseat tote gives Basic Economy flyers real packing volume without crossing into carry-on territory, and it slides under the seat where a sizer never gets involved.

Community reports describe the same pattern often. Travelers on cheap international fares are startled to learn a checked bag was never included. They pay the calculator’s price at booking rather than a lower one at the airport, since posters say airport pricing matches online pricing.

How United compares

Rivals handle this differently. Delta and American Airlines both publish clearer flat first and second bag tiers on most domestic routes. United’s calculator model means two travelers on the same flight can pay different United checked bag fees, based only on when they booked.

None of the big three legacy carriers waive the first bag on a basic fare without status or a card. Ultra low cost carriers like Frontier, Allegiant and Avelo go further, since most of them charge for a full size carry-on as well as every checked bag. On United, the carry-on stays free outside Basic Economy, and only the checked bag rides the calculator.

Check the baggage cost tool before you book to compare what a route actually costs, rather than guessing from an old number online. Our guide on how to avoid baggage fees covers the credit card and status angles in more depth.

The bottom line

There is no shortcut around United’s calculator. Your United checked bag fee depends on your route, your fare and your ticket date, and United says so plainly rather than hiding it. The cheapest honest path is to prepay early where a discount applies, pack a compliant personal item on Basic Economy, weigh every checked bag before you leave, and lean on Premier status or a United card if you already have either one.

Common questions

Does United charge a flat fee for a checked bag?

No. United prices checked bags through a per itinerary calculator that changes with your route, fare and purchase date, rather than one fixed dollar amount.

How much does it cost to check a bag on United in Basic Economy?

Basic Economy still uses the calculator for the bag itself, and if you wait to check it at the gate United adds a 25 USD gate handling charge on top.

Does prepaying for a United checked bag save money?

On some routes yes, if you prepay more than 24 hours before departure, though United does not publish the exact discount amount.

Which MileagePlus status waives the United checked bag fee?

Premier Silver waives one bag, Gold waives two, and Platinum and 1K each waive three, all up to 70 pounds.

What happens if a checked bag is overweight on United?

United weighs every bag at the counter and adds a surcharge on top of the base fee for anything over the cabin’s weight cap.

Does a United credit card cover the checked bag fee?

Many United branded cards include a free first checked bag for the cardholder and companions on the same reservation.
