United Airlines Baggage Fees 2026: Complete Cost Guide

Checking a bag on United Airlines in 2026 costs more than most travellers expect — and the rules changed mid-year. In April 2026, United raised its standard checked baggage fees for domestic and short-haul international flights for the first time since 2024, adding $10 to each of the first two bags and $50 to the third. If your mental price list still says $35 for a first checked bag, it is out of date.

This guide breaks down the complete United Airlines baggage fees 2026 schedule: what you will pay for each checked bag on every route type, who gets free bags, size and weight limits, carry-on rules (including the Basic Economy catch that surprises new flyers), overweight and oversize charges, and the practical ways frequent United flyers keep baggage costs at zero. Everything below reflects United’s current published policy, including the April 2026 increase and the separate May 2026 change for long-haul international tickets.

United Airlines Baggage Fees 2026 at a Glance

Here are the standard fees most travellers will pay. United prices checked bags per person, per direction — a round trip doubles the total unless your ticket includes free checked bags. Note that United gives a $5 discount per bag when you pay online at least 24 hours before departure, during booking or online check-in.

Bag	Pay online (24h+ before flight)	Pay at the airport
First checked bag	$45	$50
Second checked bag	$55	$60
Third checked bag	$200	$200
Fourth and additional bags	$200 each	$200 each

These are the fees United announced effective for tickets purchased on or after 3 April 2026, applying to domestic US flights and short-haul international routes (Canada, Mexico, the Caribbean, and short flights within Latin America). Before that date, the first and second bags cost $35 and $45 respectively when prepaid ($40 and $50 at the airport), and the third cost $150.

The April 2026 Price Increase: What Changed and Why

United’s April 2026 increase was part of a broader wave across US carriers. Jet fuel prices roughly doubled during the first half of 2026, and United raised baggage fees by $10 on the first two bags and $50 on the third for tickets bought on or after 3 April 2026. JetBlue and Delta announced their own increases in the same period, so United was not acting alone — but it was among the first to move, and its new $50 at-the-airport first-bag fee is now one of the highest standard domestic rates among the big three US carriers.

Three things did not change in the increase:

• Complimentary bag allowances for premium-cabin passengers, MileagePlus Premier members, eligible United co-branded credit card holders, and active-duty military members stayed in place.
• Long-haul international fees were handled separately — they changed on 12 May 2026, not 3 April, and many long-haul tickets still include at least one free checked bag.
• Carry-on and personal item rules did not change — most fare types still include one carry-on bag and one personal item free of charge (with the important Basic Economy exception below).

United Checked Bag Fees by Route Type

Domestic US, Canada, Mexico, Caribbean and short-haul Latin America

All flights within the United States (including Puerto Rico and the US Virgin Islands), plus flights between the US and Canada, Mexico, the Caribbean, and short-haul Latin America destinations, use the standard $45 / $55 / $200 prepaid schedule ($50 / $60 / $200 at the airport). This is the fee schedule most travellers will encounter, and it is the one the April 2026 increase applied to.

If you are flying round trip and checking one bag each way, budget $90 total at the prepaid rate ($100 at the airport) before any waivers. A family of four each checking one bag on a round trip pays $360 in bag fees at the prepaid rate — which is exactly why the free-bag section below is worth reading carefully.

Trans-Atlantic and Trans-Pacific flights

Long-haul international fees changed separately, for tickets purchased on or after 12 May 2026. The good news: most economy tickets on Trans-Atlantic and Trans-Pacific routes include the first checked bag free, except on Basic Economy fares. The second checked bag costs $100 in economy. Premium Plus, United Business, and United Polaris passengers receive at least two free checked bags. Because United prices long-haul baggage by market, always confirm the allowance shown during booking for your specific route.

Other international routes

Fees for other international itineraries — including South America, Africa, Asia, and Australia — vary by route, fare class, and loyalty status rather than following a single flat schedule. Many long-haul tickets include at least one free checked bag as part of the fare, particularly outside Basic Economy. The allowance printed on your booking confirmation is the authoritative figure for your trip.

Size and Weight Limits for United Checked Bags

Fees are only half the story — bags that exceed United’s size or weight limits attract separate overweight and oversize charges on top of the standard fee.

Limit	Economy / Basic Economy	Premium cabins (United First, Business, Polaris, Premium Plus long-haul)
Maximum weight	50 lbs (23 kg)	70 lbs (32 kg)
Maximum size	62 linear inches (157 cm)	62 linear inches (157 cm)

Linear inches means length + width + height measured together. Most standard large checked suitcases (around 28–30 inches tall) fall under the 62-inch limit when packed normally.

Overweight baggage fees

Bags between 51 and 70 lbs incur a $100 overweight fee on top of the standard checked-bag fee on most routes. Bags between 71 and 100 lbs cost $200 extra. United will not accept checked bags over 100 lbs. The single most common surprise fee at the check-in counter is the overweight charge on a bag that looked fine at home — a $20 luggage scale is the cheapest insurance against it. Premium-cabin passengers enjoy the higher 70 lb threshold before overweight fees kick in.

Oversize baggage fees

Bags measuring between 63 and 115 linear inches are charged a $200 oversize fee in addition to the standard fee. Bags over 115 linear inches are generally not accepted as checked baggage. If a bag is both overweight and oversize, both fees apply — an unpleasant combination that makes the luggage scale and a tape measure worth their weight many times over. If you travel with large sports equipment, read the sports equipment section below before you assume the worst.

How to Get Free Checked Bags on United

A surprising number of United passengers pay for bags they could have checked free. Here are the main ways to qualify.

MileagePlus Premier status

United MileagePlus Premier members receive free checked bags as a core elite benefit. Premier Silver members get one free checked bag (up to 50 lbs) on United-operated flights; Premier Gold members and above receive two or more free bags with the higher 70 lb weight allowance. If you fly United even a few times a year, the baggage savings alone can make chasing Silver status worthwhile — four round trips with a checked bag each way saves roughly $360 at the prepaid rate.

United co-branded credit cards

Holders of the United Explorer Card receive the first checked bag free for themselves and one companion travelling on the same reservation, provided the flight was purchased with the card and the MileagePlus number is in the reservation. For a couple checking one bag each on a round trip, that is $180 in waived fees per trip. Premium United cards go further — the United Club Card waives the first two checked bags for the cardholder. If you fly United even twice a year with luggage, the card benefit frequently covers its own annual fee.

Premium cabin tickets

Passengers travelling in United First, United Business, or United Polaris receive free checked bags as part of the fare — typically two or more bags at the 70 lb limit — and Premium Plus on long-haul routes carries two free bags. One 2026 wrinkle to know: United introduced unbundled “United First Base” fares in domestic first class this year. These cheaper first-class tickets strip out perks — no free seat selection, no itinerary changes, reduced miles — and they include one free checked bag instead of the usual two. Check which first-class fare type you booked before assuming the full allowance.

Active-duty military

Active-duty US military members receive generous free baggage allowances on United, including additional bags beyond the standard passenger allowance, when travelling with valid military ID. Present the ID at check-in to have the waiver applied.

United Carry-On Rules 2026

Most United passengers may bring one full-size carry-on bag and one personal item onboard at no charge — but there is one major exception that catches people out.

Item	Size limit	Cost
Carry-on bag	22″ x 14″ x 9″ (56 x 36 x 23 cm)	Free (most fares)
Personal item	17″ x 10″ x 9″ (43 x 25 x 22 cm), must fit under the seat	Free (all fares)

The exception: Basic Economy passengers on most domestic and transatlantic flights may bring only one personal item onboard — no full-size carry-on bag. Unlike Delta, which lets Basic Economy passengers carry on, United restricts its cheapest fares to the personal item unless you hold MileagePlus Premier status, carry an eligible United credit card, or have qualifying Star Alliance status. If you book Basic Economy with a roller bag, you will be forced to check it at the gate and pay the checked-bag fee — usually at the higher airport rate. This single rule is the most common reason United passengers pay an unexpected $50 at the airport.

How to Pay Less for United Baggage: 7 Practical Strategies

Beyond the free-bag routes above, these strategies cut what you actually pay.

1. Always prepay online — save $5 per bag

United discounts every bag by $5 when you pay during booking or online check-in at least 24 hours before departure. A family of four checking one bag each on a round trip saves $40 just by prepaying. Prepaid bags are also logged to your reservation, which speeds up the counter and avoids last-minute fee disputes.

2. Weigh your bag at home

The overweight fee is the most avoidable charge in air travel. Weigh every checked bag on a home scale before you leave. If a bag is at 49 lbs, move the heavy items (shoes, books, toiletries) into your carry-on or personal item.

3. Use the credit card benefit even if you rarely fly

If you take even two United round trips a year with a checked bag, the Explorer Card’s free-bag benefit — $180 per couple-trip in waived fees — typically pays for the annual fee by itself, before counting a single mile.

4. Consolidate bags

Two people each checking one bag costs $90 each way at the prepaid rate. One shared larger bag (under the weight limit) costs $45. Travelling as a couple or family, consolidate ruthlessly.

5. Ship heavy items separately

For moves, long trips, or gear-heavy travel, shipping a box via ground courier is frequently cheaper than a third checked bag at $200 plus potential overweight fees.

6. Wear your heaviest items

Boots, jackets, and bulky sweaters worn onto the plane do not count against any baggage limit. It is inelegant, but it works.

7. Think twice about Basic Economy with luggage

Basic Economy looks cheapest until you add a $50 gate-checked carry-on at the airport plus a $50 checked bag. Run the full ticket-plus-bags math against the standard economy fare — the gap is often smaller than the baggage penalty.

Special Items: Strollers, Car Seats, Sports Equipment, and Pets

United handles several common special items more generously than travellers expect. Strollers and car seats can be checked free of charge when travelling with a child, and collapsible strollers can usually be gate-checked at no cost. Standard sports equipment — golf bags, skis, snowboards — generally counts as a normal checked bag and pays the standard fee when it fits within the 50 lb and 62-inch limits; oversized gear such as surfboards or bicycles may trigger the $200 oversize fee, so measure before you pack. Musical instruments that fit in the cabin can be carried on subject to space; larger instruments may need their own seat.

Pets travel under separate rules and a separate service charge from baggage. Small pets in carriers may travel in the cabin on many routes; larger animals travel as cargo where permitted. Always confirm pet rules for your specific aircraft and route before booking, since restrictions vary.

Delayed, Damaged, or Lost Bags: What to Do

If your checked bag does not arrive, report it to United’s baggage service office before leaving the airport — this creates the official record everything else depends on. Keep your baggage claim tag, take a photo of it, and file the report the same day. United tracks bags through its system and delivers most delayed bags within 24 hours.

For damaged bags, report the damage at the airport baggage office before departing the terminal; claims filed later are harder to resolve. Photograph valuable contents before you pack, keep receipts for essentials you must buy while waiting, and know that international itineraries carry treaty-based liability limits.

United vs Other Airlines: How the Fees Compare

After the April 2026 increase, United’s $50 at-the-airport first-bag fee is the highest standard domestic fee among the big three US carriers — a meaningful gap given that Delta raised its own first-bag fee to $45 in the same month. Our guide to Delta Air Lines baggage fees 2026 shows how closely the two now track, while our Southwest baggage fees 2026 guide documents the end of an era — Southwest famously kept bags free for years before introducing fees in 2025. At the other extreme, our Spirit Airlines baggage fees 2026 breakdown shows how the ultra-low-cost model pairs cheap tickets with some of the highest bag fees in the industry. The right comparison is always ticket price plus baggage, not ticket price alone: a $40 cheaper United ticket can easily become the more expensive trip once bags are added.

Frequently Asked Questions

How much is United’s first checked bag fee in 2026?

$45 each way when you pay online at least 24 hours before departure, or $50 at the airport, for domestic and short-haul international flights — following the April 2026 increase. A round trip with one checked bag costs $90 prepaid ($100 at the airport) at the standard rate unless you qualify for a free-bag benefit.

Did United raise baggage fees in 2026?

Yes, twice. Effective for tickets purchased on or after 3 April 2026, United added $10 to the first and second checked-bag fees and $50 to the third on domestic and short-haul international routes. Separately, for tickets purchased on or after 12 May 2026, long-haul international baggage fees changed — though most Trans-Atlantic and Trans-Pacific economy tickets (except Basic Economy) still include the first bag free.

Can I bring a carry-on bag on a United Basic Economy ticket?

On most domestic and transatlantic flights, no — Basic Economy passengers are limited to one personal item (17″ x 10″ x 9″) that fits under the seat. A full-size carry-on will be gate-checked and you will pay the checked-bag fee. Exceptions apply for MileagePlus Premier members, eligible United credit card holders, and qualifying Star Alliance elites.

How can I get a free checked bag on United?

The main routes are MileagePlus Premier status (Silver gets one free bag; Gold and above get more), an eligible United credit card (the Explorer Card covers the first bag for you and a companion; premium cards cover two), travelling in a premium cabin, or active-duty military travel with valid ID.

What is United’s checked bag weight limit?

50 lbs (23 kg) per bag in economy; 70 lbs (32 kg) in United First, Business, Polaris, and long-haul Premium Plus. Bags over the limit incur $100 (51–70 lbs) or $200 (71–100 lbs) overweight fees; bags over 100 lbs are not accepted.

What size bag can I check on United?

Up to 62 linear inches (length + width + height, max 157 cm). Bags from 63 to 115 linear inches pay a $200 oversize fee on top of the standard fee; bags over 115 linear inches are not accepted.

Does United charge for a third checked bag?

Yes — $200 each way after the April 2026 increase, up from $150.

Are United baggage fees per person or per booking?

Per person, per direction. Two passengers each checking one bag one-way pay two first-bag fees; a round trip doubles it.

Is it cheaper to pay for bags online?

Yes. United discounts each bag by $5 when you pay during booking or online check-in at least 24 hours before departure. Airport counter payments cost the full rate.

Do United baggage fees apply to award tickets?

The same fee schedule applies to award tickets, but the same waivers apply too — Premier members, eligible cardholders, and premium-cabin award travellers still get their free bags.

The Bottom Line

United Airlines baggage fees in 2026 are straightforward but no longer cheap: $45 prepaid ($50 at the airport) for the first bag, $55 ($60) for the second, and $200 for the third on domestic and short-haul international routes. The April 2026 increase made the free-bag benefits — Premier status, a United credit card, or a premium cabin seat — more valuable than ever, and the Basic Economy carry-on restriction makes the cheapest ticket genuinely expensive for anyone with a roller bag. Before your next United trip, check whether you already qualify for a waiver, weigh your bag at home, and prepay online at least 24 hours out. Those three steps are the difference between $0 and $100 on a simple round trip.
