United Airlines Flights Information

Hand Baggage Allowance

Each passenger is allowed to bring one carry-on luggage item as well as one small personal item for each flight. A traveler’s carry-on bag and personal item must be able to easily fit in the overhead bins or under the seat in front of them at the cabin crew’s discretion.

Maximum dimensions allowed for carry-on luggage are 9 inches x 14 inches x 22 inches (22 cm x 35 cm x 56 cm) including both the wheels and handles.

A personal item is generally defined as a purse, handbag, laptop or briefcase, book bag, or other similarly sized item. Maximum dimensions allowed for a small personal item are 9 inches x 10 inches x 17 inches (22 cm x 25 cm x 43 cm).

Checked Baggage Allowance

Checked baggage service charges apply at any point where bags are checked, although some customers are exempt from charges for bags within specified size and weight limits. Services charges for the first two check baggage items may apply for bags with a maximum weight of 50 lbs and a maximum exterior dimension of 62 inches. Any additional bags that exceed the maximum weight or size limits are considered excess baggage and may be subject to additional fees or regulations. MileagePlus members, active military personnel or their dependents may be exempt from checked baggage service charges for one or more of their luggage items as long as these items meet the weight and size requirements. This exemption does not pertain to group reservations of ten or more passengers or when the flight is not operated by United or United Express services. Passengers are recommended to carry all delicate and valuable items with their carry-on luggage, as the TSA is required to perform a comprehensive screen on all checked baggage. These screening procedures are not considered the liability of United Airlines.


Check-in is available within 24 hours of the flight’s scheduled departing time. Online check-in is the recommended method as it is fastest and boarding passes can be printed from a home computer. A message containing a link to your boarding pass can also be emailed to most mobile devices or laptops to be shown to check-in staff. A United Airlines app is also available for smartphone devices and can be used to instantly check-in before departure times. Regardless of check-in time, all baggage must be checked at least 30 minutes before domestic flights and 60 minutes before international connections.

Boarding Information

Most domestic flights are boarded up to 15 minutes before the scheduled departure time. With most US airports suggesting at least an hour and a half processing time, United Airlines recommends arriving at least two hours before departure. Arriving at the departure gate at least 30 minutes before the scheduled departure time is also highly recommended. Peak traffic hours at most airports are between 6:30 a.m. – 9:30 a.m., 11:00 a.m. – 2:00 p.m., and 3:30 p.m. – 7:30 p.m. Travelers should keep in mind that proper identification is required at all check-in desks, TSA stations and at the departure gate.

Frequent Flyer Information - MileagePlus

United Airlines offers a frequent flyer program, entitled MileagePlus, that has been voted the world’s best frequent flyer program for nine consecutive years by Global Traveler magazine. “Miles” are earned by purchasing tickets, hotel reservations, car rentals and other services. Credit cards are offered that collect MileagePlus miles through standard purchases and other bonus reward programs. Amtrak tickets can also gain MileagePlus miles as well as trips planned through United Cruises and United Vacation services. MileagePlus miles can be used to purchase United Airlines tickets as well as many other services provided by United Airlines and its partners. Flight upgrades can be made with MileagePlus miles giving passengers access to premium flight cabins, checked bag allowances and complementary premium beverages. These upgrades can be made before or after tickets and reservations are purchased, although certain benefits are only available if upgrades are made prior to check-in. Miles can also be used to book reservations at many brand-name hotels or pay for a membership to United Airlines’ United Club and Lounge located at many airports worldwide. These lounges provide free snacks, beverages and Wi-Fi for members and are also partnered with other airport lounge services to ensure that MileagePlus travelers have a private and relaxing atmosphere while waiting for connecting flights. Miles can also be donated to charities through United’s donation services. A complete list of charities is available on their website and covers a wide range of non-profits and other similar associations.

General Information

What would become United Airlines completed its first commercial flight in 1926 and eventually merged with William Boeing's aircraft and carrier company to create the United Aircraft and Transport Corporation. By 1933, United was the first airline company to fly an all-metal aircraft, the famous Boeing 247. After merging with Capital Airlines in the 1960s, United Airlines became the USA's largest airline company and remained so for many years. Continuing to control a large portion of American airline traffic, United Airlines also became the first airline company to fly the now standard Boeing 747 and after becoming employee-owned through a stock ownership program, became the world's largest employee-owned corporation in 1994. United Airlines is based in Chicago, Illinois in Willis Tower (once known as Sears Tower) and operates over 700 mainline aircraft. The company currently boasts over 85,000 employees in the United States and countries around the world. As one of the world's most comprehensive and longest operating airline services, United Airlines is one of the USA's most traveled carriers. An average of over 5,200 flights are made daily to more than 350 airports worldwide and the airline has handled nearly 140 million passengers yearly since 2012. United Airlines also prides itself on being an environmentally sensitive corporation, flying the world’s first commercial aviation flight on certified bio-fuel. They have also campaigned to replace all paperwork with Apple’s iPad technology and have purchased over 100 fuel efficient Boeing 737 Max 9s to replace less efficient older models.

it was very sad. They cancelled the flight. I passed the night at the airport. They send by other airline the next day. Don´t compensate. No hotel, no food.

It is incredible that both of my flights got delayed and that I had to spend more money than expected bc of this, and that's not the worst part. I don't live in Mexico City, as someone who travels from other cities, I spent 8 hours waiting to leave because that freaking flight got delayed for so long

Average Rating3.0/5

Did not appreciate the fact of being charged again to come back.And also to pay AGAIN for my luggage.

Pricey flight, crowded (no room in overhead compartments), uncomfortable center seat, but a mostly smooth flight. Flight home, on a different airline, was better. Surcharges each way for checking a bag.

From Portland to Denver, the flight was absolutely great. Excellent aircraft and excellent crew.

I didn't like.
