United Airlines baggage

United Airlines baggage rules usually allow one personal item that fits under the seat. Standard carry-on eligible tickets also allow one full-size carry-on bag up to 9 x 14 x 22 inches, including handles and wheels. Basic Economy can be more restrictive on many routes and may include only a personal item unless an exception applies.

Checked baggage depends on route, fare, cabin, MileagePlus Premier status, Star Alliance Gold status, eligible United credit-card benefits, military exceptions and the operating carrier. United asks passengers to use the checked bag fee calculator because prices and included allowances vary by itinerary. A standard checked bag is commonly limited to 50 lb or 23 kg and 62 inches or 158 cm in total dimensions, while some premium cabins and elite benefits allow heavier bags.

Extra, overweight, oversized, sports and special baggage can carry separate fees and may be limited by aircraft, route, season, airport or destination embargoes. If the first operating carrier is not United or United Express, that carrier's baggage policy may apply.

United Airlines check-in

United Airlines check-in is available online, in the United app, at airport kiosks and at airport counters. Online check-in starts 24 hours before scheduled departure.

Minimum times for check-in, checked-bag acceptance and boarding vary by departure airport and destination. Passengers should check the airport-specific deadline in the booking, especially for international flights, Basic Economy, pets, special assistance, paper document checks or partner-operated itineraries.

United Airlines fares and services

United fare and cabin products include Basic Economy, United Economy, Economy Plus, United Premium Plus, United First, United Business and United Polaris business class, depending on route and aircraft. Fare availability and names can vary by market and sales channel.

United Premium Plus is a premium economy cabin on selected long-haul aircraft. United First and United Business provide premium short-haul or regional business cabins, while United Polaris is the long-haul business-class product with lie-flat seats on eligible aircraft.

Changes, refunds, seat selection, upgrades, mileage earning, bags, meals, lounge access and priority services depend on the exact fare, cabin, route, ticketing country, loyalty status and operating carrier.
