United Airlines Baggage Policy is designed to offer clarity and convenience to travelers. Passengers are allowed one carry-on bag and one personal item, such as a purse or laptop bag, free of charge on most fares, excluding Basic Economy. Checked baggage fees vary depending on the route, ticket class, and MileagePlus status, with discounts often available when paid in advance online. Standard checked bags must not exceed 50 pounds and 62 linear inches. Overweight or oversized luggage incurs additional charges. United also allows certain sports equipment and musical instruments under specific guidelines. Travelers are encouraged to review their baggage allowance based on their itinerary to avoid unexpected fees at the airport.
