United Airlines baggage allowance: cabin bag, personal item and checked-bag basics
United’s normal allowance is an overhead carry-on plus a compact personal item, but Basic Economy is the critical exception to check before you pack.
What to check before you pack
One personal item; carry-on not included on most Basic Economy fares. Basic Economy, route, Premier status, card benefits, United Express, and partner-carrier rules can change your allowance.
Baggage allowances can change and may differ by fare, route, and cabin. Confirm the final allowance shown in your booking or on the airline’s official site before you fly.

| Checked baggage | Fare- and route-dependent. Use the official policy and your booking to confirm included pieces, weight, and any purchase options. | ||
Cabin bag versus personal item
The cabin bag is generally the larger overhead item. A personal item or small bag is the compact item intended for the space under the seat, when the airline permits one separately.
Checked-bag basics
Checked baggage travels in the hold. The included amount can differ more than cabin baggage does, so do not rely on a generic number when your booking lists a fare-specific allowance.
Find a bag that fits
Check your personal item before the airport does.
Open the existing Under-Seat Bag Finder with United Airlines selected. It compares a packed bag with the published personal-item rule when one is available.

Most Basic Economy fares allow only a personal item, although some international routes are exceptions. United Express flights can have tighter cabin-space constraints.
Common questions
Does United Airlines allow a personal item?
The reviewed policy record lists a personal item or small bag as included in the stated scope. Check the published dimensions and your fare before travel.
How do I check my United Airlines fare’s allowance?
Open the official policy, then confirm the baggage allowance displayed in your booking. Cabin, fare, route, operating carrier, and loyalty benefits can affect it.
What happens if my bag is too large?
It may need to be checked and a charge can apply. Do not assume a soft bag, cabin-space availability, or a previous trip will override the published rule.
