United Airlines Carry-on Baggage Rules
According to United Airlines’ baggage policy, all United Airlines passengers can take one personal item. In addition, all passengers can also take a standard carry-on bag except those traveling on a basic economy ticket. However, on some flights, even basic economy customers can have one carry-on bag.
This applies on transatlantic flights to or from the United States, Central America, Mexico, Panama, El Salvador, and South America and transpacific flights flying into or out of the United States.
If you are flying with basic economy tickets and wish to take a carry-on bag, you will have to check your bag with the applicable baggage fees and an additional $25 fee as gate handling charges. This is waived off in case you are a MileagePlus Premier member, Star Alliance god member, or MileagePlus credit cardmember.
Another exceptional case when your carry-on bag may not be allowed is when you are traveling on a smaller aircraft. For example, regional airlines that partner with United Airlines under the name United Express may not have enough space in the overhead bin. Therefore, you must check if your suitcase fits in it.
Among all the United Express flights, Air Wisconsin and CommutAir allow their passengers to carry only a personal item for this reason. Anything else will be added to the cargo compartment. Gojet Airlines, Mesa Airlines, Republic Airways, and SkyWest allow a personal item and a carry-on bag.
Weight and Size restrictions
United Airlines baggage policy states that your personal item must be of dimensions no bigger than 17 x 10 x 9 inches and must fit under the seat in front of you on the flight.

Carry-on bags can measure up to 22 x 14 x 9 inches. Note that these measurements include wheels and handles.

What can your personal item be?
Your personal item can be a purse, shoulder bag, or laptop bag. In addition to this and your carry-on bag, you can bring a jacket, an umbrella, or food purchased at the airport. You can also carry a diaper bag, a breast pump, a camera, or a safety seat approved by the FAA.
Since your personal item is the only thing you can carry for free on a basic economy ticket, ensure that you pack all your essentials in it.
Musical Instruments
You can take some musical instruments like a violin, a guitar, or any small instrument in a hard case, as carry-on baggage. Placing it in the overhead space will make it count as your carry-on bag. If you keep it on your lap, it will count as your personal item.
Assistive Devices
You can also bring any assistive devices like collapsible wheelchairs, portable oxygen concentrators, walking sticks, or devices for prescribed medications free of charge.
Inside your carry-on bag
United Airlines ensures that the Transportation Security Administration guidelines are adhered to.
Electronics
You must carry laptops in checkpoint-friendly bags. This means that there should be a laptop-only section with no pockets inside or outside it, and the section should completely unfold to lie flat for screening on the X-ray belt. The laptop-only section of the laptop bag should also not have any buckles, zippers, or metal snaps on top of or underneath it. You should place nothing in it but the laptop itself.
Tablets, handheld game consoles, e-readers, and other electronic devices larger than a cell phone will have to be taken out from your carry on bag for X-ray screening too.
Lithium batteries can be taken in your carry on bag as long as they are under 100 Watt-hours of energy.
Sharp items
Knives are usually not permitted. Pocket knives, retractable or foldable blades, box cutters, scissors with pointed tips, and razors cannot go in your carry on bags. Your carry on bag can only contain plastic or round-bladed butter knives.
Aerosols, liquids, and gels
There are special restrictions on transporting aerosol items, gels, and other liquids in carry on bags. Any liquid toiletries you take with you into the cabin should be under 3.4 ounces in quantity and fit in a clear, sealable bag. You may have to remove the bag from your carry-on bag for inspection. Each passenger is allowed only one such plastic bag. This is known as the 3-1-1 rule.

If you need to carry these items in higher quantities, they must go into your checked bags.
However, you are now allowed to take upto 12 ounces of hand sanitizer in your carry on bag. This will definitely need additional screening since it will be in a bigger container than the usual 3.4 ounces.
Also, items like baby food, breast milk, packaged milk, juice, and medications might be allowed in quantities over 3.4 ounces. Still, they will have to be declared to the security officials for screening.
You are allowed to carry toiletries or beverages that you purchase beyond the checkpoint at the airport. You must, however, remember that if you were to go through another security checkpoint at a stopover, you might have to throw those items away.
If you are flying internationally into the United States and are connecting to another airplane, you can carry liquids over 3.4 ounces, provided you purchased them in a duty-free store. You should have made the purchase less than 48 hours before the screening, and you will need to show a receipt to prove the same. Ensure that the product is put in a secure and tamper-evident bag and is screened and cleared by security officers. Sometimes, they may not be able to screen liquids in ceramic, opaque, or metallic bottles. In such cases, you will have to move them into your checked baggage or dispose of them.
The country you are traveling to may have additional restrictions on gels, liquids, and aerosols. In addition, you might want to check out the website of your departure airport to avoid any last-minute troubles at the checkpoint.
Powder-based items
It is best to put any power-like items in your checked baggage. If you are traveling to any place in the United States, you cannot carry power-based substances in quantities more than 12 fluid ounces into the flight cabin with you. However, things like baby formula, duty-free powders, and human remains are allowed in tamper-evident bags.
Cabin seat baggage
Items that are too sensitive or fragile to be passed as checked baggage can be considered cabin-seat baggage. They can be some musical instruments, artifacts, media cameras, garment bags, et cetera.
After being approved by a United agent, you can purchase a ticket for such an item. It can then travel with you, on a seat in the cabin. The item must weigh under 75 kilograms and be packaged safely. It should be secured by the seat belt and should not obstruct the view of any signboards like ‘no smoking’, ‘seatbelt’, or ‘exit’ on the flight. It should also not restrict the ability of passengers to reach the cabin’s aisle side of the emergency exit.
You can discuss the charges applicable for the item with the agent only.
United Airlines Checked baggage rules
Let’s look at the policies and applicable baggage fees for checked bags in United Airlines.
Weight and Size restrictions
The checked baggage rules in United Airlines baggage policy state that the linear dimension, the sum of length, height, and width of your bag, including wheels and handles, must not exceed 62 inches.
