United Airline’s liquids, gels, and aerosols rules 

United Airlines restrict the carrying of fluid or gaseous items, especially as part of your carry-on luggage following the TSA restrictions on liquids, gels, and aerosols. These restrictions include: 

  • United liquid, gel, aerosol max size: 3.4 oz or 100 ml 
  • The above is the size of the container (bottle/tube/jar), not how much liquid/cream is left in the container. 
  • All the liquid, gel, and aerosol items you carry in your United personal item or carry-on must be kept inside a single quart-size clear plastic bag (6’ × 9’). You can get many of these online. The size may vary a little bit as long as it sums up to 1 quart (946 ml) or less. 
  • You have to place the bag in a separate bin while checking in. 
  • Exceptions:  
    • Medicines and infant nursing liquids are not counted in these rules – they have separate rules.  
    • Duty-free items – only on international flights, packed in original clear bags provided by the vendor, and you have to show the receipt too. 

How to Save on United Airlines carry-on Price when Flying Basic Economy

If you are caught at the gate with a united basic economy ticket and a full-sized carry-on, then it will have to be checked in, and the relevant charges (usually $30) paid. Furthermore, you will be charged $25 extra because of the gate check. 

If you need to take carry-on luggage with you even when you are flying Economy, here are some tips on how you can avoid paying extra.

1. Pay with a co-branded United credit card 

This is the most common way to avoid the United Carry-on fee and also get some extra advantages. If you use one of the following cards, you can bring a carry-on bag onboard with a United basic economy ticket. 

Table of United co-branded credit cards 

UnitedSM Explorer Card      UnitedSM Business Card      UnitedSM Infinite Card      MileagePlus Club Card      Presidential PlusSM Card     MileagePlus Awards Card      Ixe United Universe Card      Presidential Plus Business Card      Ixe United Card      Note: any carry-on luggage you take onboard a United flight using these methods is still restricted by United carry on size and number restrictions, and the items within it are restricted by the United carry on item regulations.  

2. Be an Elite Traveler with United  

If you travel frequently on United flights, you can accumulate enough miles to achieve Elite status. This is most suitable for business travelers who travel a lot. When you achieve this status, and you hold one of the following memberships, you will be allowed to take a carry-on (subject to restrictions and space availability) onboard the United flight with just a basic economy ticket. The list of such memberships is: 

  • MileagePlus Premier Silver 
  • Premier Gold, Premier Platinum, and Premier 1K  
  • Star Alliance™ Gold 

How to Handle United Basic Economy Bag Issues 

There are some restrictions on baggage in the United basic economy class. These are the following: 

  • You cannot bring a full-sized carry-on bag on a United basic economy class ticket.  
  • You are allowed only a small united personal item or your pet carrier, which must fit under the seat. 
  • If you bring a full-sized carry-on bag on a basic economy ticket: 
    • It will be checked in and you have to pay the applicable united checked baggage fees ($60, $100, and $200 for the first, second, and third bag). 
    • You will also have to pay the gate handling fee ($25). 
  • Mobility or assistive devices (like foldable wheelchairs) are not counted in this rule. 
  • This rule does not apply on united transatlantic flights. 

This means if you’re traveling basic economy on United, you will have to pay for your carry-on bag, a minimum of $60, and up to $225. So, how do you avoid paying for United carry-on in the basic economy?

  1. Book the flight using a co-branded United credit card.  
  2. Become a privileged customer with United Airlines.

Can I take a backpack and a carry-on United? 

United Airlines allows each passenger one free personal item and one free carry-on bag. If your backpack and carry-on are smaller than those sizes, then sure you can bring them on board free of cost. However, make sure that your personal item can and the backpack fits in the bin. Check the best backpacks you can bring on your next travel.

Can I bring makeup to my carry-on? 

There are not any restrictions for solid-type make-up (i.e. lipsticks) However, if you are bringing fluid types of makeup (liquid, flowing powder, gel, cream, etc.) then you have to obey the TSA restrictions, which are basically: 

  1. The containers (bottle, tube, jar) must be less than 3.4 oz (100 ml) or less in size 
  2. You must place all of them inside one quart-size bag (6” x 9”), of clear plastic. 

How do I get a free checked bag on United? 

  1. Pay using a United co-branded credit card, like a United Explorer card, MileagePlus Club card, Ixe United Universe card, etc. 
  2. Become an elite flyer in some of their privileged memberships, like MileagePlus Premier, Premier Gold, Star Alliance Gold, etc. 

How many 3 oz bottles can I take on a plane? 

According to the TSA, you can carry a few 3 oz or fewer bottles, tubes, etc. in your united carry-on as long as they all fit inside one 6” x 9” quart-sized clear plastic bag. Generally, it isn’t capable of holding more than 3-4 items of 100ml size, that should be your rough limit. 

Do make sure you’ve checked the united restricted items guide first, though, because you have to present the plastic bag at security in a separate bin for checking.
