Checked baggage with United Airlines: what you need to know
United Airlines's checked baggage allowance depends on your fare, route and travel class. Your ticket or booking confirmation should be treated as the final entitlement.
As a useful starting point: standard Economy checked bag up to 23kg; premium cabins up to 32kg; inclusion/fees vary.
Additional baggage can usually be purchased on eligible itineraries. Booking before reaching the airport is generally safer and often cheaper than relying on airport excess-baggage charges.
Overweight, oversized and special baggage is subject to separate limits and charges. Never assume that paying an excess fee means an individual bag can exceed the airline's absolute maximum weight.
If your itinerary includes another airline or a codeshare flight, check which carrier's baggage rules apply before travelling.
United Airlines cabin baggage rules: liquids, extras and restrictions
The standard main cabin-bag limit is 56 × 35 × 23cm, with no general published weight limit, although the number of pieces included can depend on fare and travel class.
The allowance also includes or may include personal item up to 43 × 25 × 22cm. The smaller item should fit beneath the seat where required.
Lower-cost fares can have more restrictive cabin-baggage entitlements, so confirm whether the overhead-locker bag is included.
Cabin baggage that exceeds the permitted number, dimensions or weight can be moved to the hold and additional charges may apply.
Liquids, gels, creams, pastes and aerosols remain subject to airport security requirements. Where standard restrictions apply, use containers of 100ml or less in the required transparent, resealable liquids bag.
CabinCleared's branded travel-size toiletries can help you use your United Airlines cabin baggage efficiently while keeping everyday essentials accessible.
Power banks and spare lithium batteries should be kept in cabin baggage rather than checked luggage, subject to the airline's current capacity, quantity and approval rules.
