United is a US Star Alliance major: Basic Economy is tightly unbundled on cabin bags and changes, while Economy and higher restore a standard carry-on. Checked bags are typically paid on domestic tickets unless a MileagePlus or card perk applies. International brands vary — price the all-in total through United hubs. This page summarises United (UA) carry-on, checked bags, changes, seats and pets for July 2026 planning. Fare rules in the United app beat any blog table. See [airline carry-on sizes 2026](/guides/airline-carry-on-sizes), [airline baggage fees compared 2026](/guides/airline-baggage-fees-compared), [flight delay compensation rights](/guides/flight-delay-compensation-rights), and compare UA with [Lufthansa](/airlines/lufthansa) on Star Alliance routings via [flight deals](/deals/flight-deals). Figures below are illustrative planning bands as of July 2026. Fare families, routes and MileagePlus status rewrite the numbers — confirm on the airline site for your PNR before you pay or pack. ## What is the United carry-on size and weight limit? Most United Economy tickets allow one carry-on commonly described around 22×14×9 inches (about 56×35×23 cm) plus a personal item. Basic Economy on United metal typically allows only a personal item that fits under the seat — a full-size carry-on can trigger gate fees or forced checking. Partner segments may differ. This Basic Economy personal-item rule is the classic United trap for travellers coming from Delta-metal habits. Read the fare tile twice. US United flights rarely weigh cabin bags, but Star Alliance long-haul partners might. Pack for the strictest kilogram rule on the journey and keep essentials in the underseat bag. ## How much does United charge for checked bags? Many United US domestic Economy tickets charge for the first and second checked bags unless a credit card or MileagePlus benefit covers them. Some international Economy brands include bags. Prepaid rates in the United app beat airport prices; overweight fees escalate above 23 kg / 50 lb. Illustrative US domestic first-bag prepaid bands often sit roughly in the $35–$45 range with second bags higher — planning bands only as of July 2026.

Most United Economy and higher tickets no longer charge change fees on many routes, though fare differences still apply. Basic Economy remains largely non-changeable and non-refundable for convenience. United-led disruptions open rebooking or refund pathways under airline and applicable law. Watch the 24-hour refund window on qualifying direct bookings. Award tickets use MileagePlus charts, not cash Economy rules.

Economy may select standard seats free in a window or pay for Economy Plus extra-legroom seats. Exit rows cost more and carry restrictions. MileagePlus elites select earlier and often see Economy Plus perks by tier. Illustrative Economy Plus prices jump on transcontinental and Hawaii peak dates. Families should not gamble on Basic Economy assignments. ## What is the United pet policy? United generally allows small dogs and cats in the cabin on selected routes with a pet fee and underseat carrier limits, with caps per flight. Checked pet options are limited compared with older programmes; cargo arrangements handle many larger relocations. Service animals use a separate process. Reserve in-cabin pets when you book — summer heat embargos are real. International paperwork is yours. Partner-operated segments may refuse a pet confirmed only on United metal. ## What is the practical bottom line before you buy United? Never buy United Basic Economy if you need a wheeled carry-on — that personal-item rule is the classic fee trap. Add bag and Economy Plus maths to Economy fares, then compare United with Delta, American and Star Alliance partners on the same dates before you commit. Screenshot bag and seat lines after purchase — card benefits fail silently on some branded fares.
