About United Airlines

United Airlines is one of Forbes’ top 15 U.S. airlines, as ranked by on-time flights and customer complaints. Only 15% of its lights take off late, and it has one of the most diverse domestic and global destination portfolios. It offers economy, business and first class flights, allowing its clients to use points against its booking fees. The airline is known for its competitive prices. If you’re taking a United Airlines flight from one of its hubs, you’ll enjoy extra benefits, such as their famous Polaris Lounge. The company has partnerships with several airlines, including Air China and Air India. These alliances are designed to fulfil clients’ needs more comprehensively, adding MileagePlus miles, lounges and new routes to their offerings. Its global partners increase the number of connecting flights exponentially. Its fleet is dominated by Airbus and Boeing planes, the largest of which carries 335 passengers. It recently acquired a Boeing 737 Max 9, which has been designed to fly quietly and economically. United was founded in the 1920s, quickly rising to become the largest airline in the world in terms of revenue.

How do I check in online with United Airlines?

The United Airlines online check-in option is available 24 hours before your flight and can be completed in English, French or Spanish. The site lets you print your boarding pass or link it to your mobile phone. The screen barcode is all that’s needed at the security checkpoint, letting the airline achieve an almost paperless process. Online check-ins are only offered if your first flight is within the United family and you’re travelling with a maximum of nine people. You must scan your passport using the app or at an airport kiosk. Simply log in to the flight check-in page and enter your eTicket or confirmation number. Then, check your bags in 60 minutes before your flight. Its online tools and applications let you track the status of your flight and even allow you to change your flight on the go.

What is my checked baggage allowance on United Airlines?

The United Airlines baggage allowance is a standard 23 kg. Hold luggage is limited to two items of baggage measuring 157 cm. Extra lithium batteries for smart luggage must be removed and carried as part of your hand luggage. Premier Platinum members are allowed more weight, at 32 kg, and 157 cm including wheels. Extra baggage will be charged for, but is only allowed if the plane has sufficient room to accommodate it. Medical and mobility devices generally don’t attract a charge. Passengers may not carry flammable fluids, including paints, mace and other defence sprays. E-cigarettes must be packed in carry-on luggage. Valuable items, such as antiques and business equipment, are not covered by the airline’s insurance, so make sure you cover them before you fly. Most sports equipment is allowed, as long as the service charge is covered, but self-propelled items such as hoverboards are restricted. If you’re travelling with partners such as Lufthansa, your baggage restrictions may vary, particularly if you’re not flying from one of the airline’s nine hubs.

What hand luggage can I take on United Airlines?

The United Airlines hand luggage size limit is 56 cm x 36 cm x 23 cm. Basic economy travellers are allowed to take one bag and a personal item such as a laptop bag or purse as carry-on luggage. You’re allowed to carry food you bought at the airport, and medical devices such as oxygen or crutches. Pet carriers are allowed but may be charged for. Parents may carry child safety seats and diaper bags onto the plane. Any liquids must be limited to 100ml per bottle, which must be sealed in a clear bag unless they were bought at a duty-free store and are in secure packaging. If fluids can’t be screened due to the opacity of their packaging, they must be packed in your hold luggage. Small musical instruments can be taken on board if they can be stowed away under your seat. The airline allows you to carry a stroller and car seat for every child younger than 2. Infant tickets are about 10% of standard flight costs unless your child doesn’t need her own seat. If you’re taking liquid medications, they must be bottled in 3.4-ounce containers and declared at the checkpoint. All medications must be accompanied by a doctor’s prescription or letter.

Where does United Airlines fly from?

United Airlines destinations are updated every year. Currently, the airline has 78 local and 108 global destinations to provide the most convenient routes possible. As it grows its national presence, it gives its clients an increasing number of connecting options. These are built around its domestic hubs. This way, those who’ve previously had few flight options within their home region are now given new connections and destinations. These are further supported by United’s partner, Air Canada. Some of United's current routes include:

  • Denver to London flights
  • Houston to Sydney flights
  • New York to Reykjavik flights
  • Washington DC to Edinburgh flights
  • Chicago to El Paso flights
  • Houston to Akron flights
  • Los Angeles to Redmond flights
  • Denver to Appleton flights
