This quick guide will give you a good idea of what to expect, and we’ve linked to other comprehensive guides to help you with the requirements for your particular itinerary.

United Airlines Carry-On Policy

In 2026, your United baggage allowance depends strictly on your fare. While most tickets include a carry-on, Basic Economy usually limits you to one small item under the seat.

• Standard Tickets: One overhead bag plus one small personal item are included.
• Basic Economy: Just one personal item on most domestic flights
• Size Matters: And don’t forget the wheels and handles, or you’ll pay

Check Baggage policy

United’s baggage rules can’t be boiled down to just weight when you check a bag in 2026: They’re really a combination of flight destination and seat class. A regular Economy ticket usually incurs a fee for the first checked bag on domestic flights, but international travelers and those in premium cabins often receive a much more generous allowance. And, because going just one pound or one inch over the limit can result in significant extra fees, it’s always a good idea to screw in the family suitcases at home and weigh them to make sure they’re within your fare’s baggage limits.

• Quality of Service and Flight Destination Matter: Your baggage allowance depends on whether you’re flying internationally or domestically, and whether you’re booked in Basic Economy or Polaris.
• Mind the Weight: The maximum weight is usually 50 lbs for Economy bags, 70 lbs for Business and First.
• Size Matters: Standard bags can’t exceed 62 linear inches (length + width + height) as oversized baggage is subject to fees.

Baggage Fees Overview

When it comes to estimating United baggage fees for 2026, the end figure is rarely a set rate, rather a function of your itinerary and how many bags you’re lugging, and fees often climb with each additional piece. So, pay close attention to your packing, as moving into the “overweight” or “oversized” category can mean additional penalties that far exceed the original fee. But don’t worry, a certain amount of preparation can save you money, as United often offers a small discount if you pay your baggage bill online at least 24 hours before heading to the airport.

• Variable Rates: Fees vary based on your destination and number of bags checked
• Size & Weight Penalties: Fees may apply for bags over 50 lbs or 62 linear inches
• Prepayment Perks: Paying for your bags through the app or website early can save you money.

Personal Item Policy

When you’re flying United in 2026, your personal item is the one piece of luggage that stays with you, tucked right under the seat in front of you. This is usually something like a handbag, a small backpack, or a laptop case basically, any compact bag that doesn’t need to go in the overhead bin. Even if you’ve booked a restricted Basic Economy fare, this item is always included for free. Just make sure it actually fits in that under-seat space; if it’s too bulky, you might be asked to check it at the gate, which usually comes with an extra fee.

International Baggage Rules Policy

Flying internationally with United in 2026? Your baggage rules will be a lot different than on the domestic side of things. They’re closely tied to your destination and your class of service. So while a long-haul flight to Europe or Asia might come with at least one checked bag included (for free), some of the shorter international flights may carry domestic fees. It’s a gradient. There is more flexibility if you travel in premium cabins and have elite status. But, of course, make sure to check the baggage rules on your specific itinerary.

• Destination Driven: Your free bag count changes depending on whether you’re crossing the Atlantic, the Pacific, or just heading to Canada or Mexico.
• Cabin Perks: Flying in Premium Plus or Polaris almost always guarantees at least two free checked bags with a higher weight limit.
• Basic Economy Exception: On certain long-haul international routes, Basic Economy might actually include a full carry-on bag, unlike domestic flights.

Special Baggage Categories

Sports Equipment

Most gear, like golf clubs or skis, counts as a standard checked bag. While United often waives oversize fees for these items, keep an eye on the weight to avoid extra charges.

Musical Instruments

Small instruments can usually come on board as your carry-on if they fit in the overhead bin. For larger pieces, you might need to check them or even book an extra seat.

Infant Travel

If you’re flying with a little one in 2026, United lets you check one stroller and one car seat for free, whether at the gate or the ticket counter.

Traveling with Pets

In 2026, only small cats and dogs can fly in the cabin for a set fee, provided they stay in a carrier under the seat. Checking pets as baggage is no longer an option for most travelers.

Military Travel

U.S. active-duty military members receive plenty of baggage free allowance in 2026 – up to five free checked bags while traveling on official orders.

Baggage Issues and Claims

Lost Baggage

If your suitcase doesn’t show up on the carousel, you need to report it at the airport’s baggage office immediately to get a tracking number. Most bags are just delayed and usually turn up within 24 hours.

Damaged Baggage

Notice a broken wheel or a major tear? Flag it to a United agent before you leave the airport. They typically need to inspect the damage in person to start a formal claim for repairs or replacement.

Lost Item on Plane

Left your phone or jacket in the seatback pocket? You’ll need to fill out an online form with your seat number and flight details so the cleaning crew can try to track it down for you.

Important United Airlines Baggage Restrictions

If you’re flying United in 2026, it’s good to know that carry-on limits are taken seriously. Basic Economy passengers in particular may be limited to just one under-seat item. Your main bag must fit within the normal 22 x 14 x 9 inch limit, including wheels, otherwise beware a costly gate-check. In addition to sizing you’ll want to know that items such as loose lithium batteries and large liquids that can’t pass through security are restricted; double-check your flight’s rules online before you go to ensure the smoothest boarding experience.

• Size Matters: Carry-ons must fit inside the 22 x 14 x 9 inch sizers; personal items are limited to 17 x 10 x 9 inches;
• Check Restricted Items: Don’t pack power banks in checked luggage; they belong in your cabin bags.
• Verify Your Fare: Basic Economy rules vary by route, so check your bag allowance on the United app before you pack.

United Airlines Baggage Policy by Fare Type

Fare Type	Carry-On	Checked Bag
Basic Economy	Restricted to a small personal item only.	Usually involves an extra service fee.
Economy	Standard overhead and personal item allowance.	Pricing depends on your specific flight route.
