Is United Airlines Good?

Is United Airlines a good airline? Across almost every metric, it sits squarely in the middle relative to other U.S.-based airlines.

It generally falls short of heavy hitters like Delta Air Lines and Alaska Airlines, but expect a far better experience particularly compared to budget airlines like Spirit Airlines and Frontier Airlines.

NerdWallet analyzed the United flying experience across several factors including United's loyalty program, its overall boarding and in-flight experience, and its reliability.

MileagePlus, United's loyalty program

NerdWallet analyzed the best airline loyalty programs for 2024, and the results may have been disappointing for fans of United Airlines. Compared with nine other airlines, United's MileagePlus program ranked fourth for both the best airline rewards program.

That said, beyond MileagePlus, there are several other factors to consider when flying United.

What is United Airlines like?

Your experience on United may change depending on the class of service, the destination you're flying to and other factors, like flight crew and passenger load. We’ve highlighted a few points that should give you a better idea of what United Airlines is like:

• Making reservations. Making reservations on United is relatively easy and can be done online, on its app, on a third-party site (like Expedia or Kayak), by calling its reservation line, or even in person at the airport. In the U.S. and Canada, United charges a $25 service fee when booking by phone and charges even more in person, so you should try to book online when possible. In other countries, charges vary.

• Check-in. Online check-in is available for eligible flyers starting 24 hours before departure, and it’s easy to do so using United’s website or app. You can also check in at the airport in person.

• Boarding. When it comes time to board your United flight, you’ll be placed in one of five boarding groups. These groups are based on your status level with the airline or Star Alliance, your cabin level, or if you hold a United credit card, such as the United℠ Explorer Card or the United Club℠ Infinite Card. Pre-boarding may also be available for families traveling with a child 2 years or younger, those who need extra time due to a disability, active military members, minors traveling alone, and United Global Services or Premier 1K members.

• In-flight experience. Your in-flight experience on United can vary widely depending on the cabin you’ve booked and the plane you’re flying on. For instance, if you’re flying United’s Polaris business class, you can expect direct aisle access from all seats, a lie-flat seat, a large screen to watch in-flight entertainment and sometimes even a sundae cart. In other cabins, you may be able to access in-flight entertainment only on your personal cell phone or tablet, and space may be more limited. Because of this, we recommend researching the plane you’ll be flying in and the in-flight experience offered in your cabin before booking.

• Loyalty program. As previously mentioned, United’s loyalty program, United MileagePlus, isn’t stellar when compared with most other domestic airlines. That said, you can sometimes use your MileagePlus miles for some great partner premium airline redemptions (for example, 75,000 miles from San Francisco to Zurich on Swiss Airlines business class).

United customer satisfaction

Compared to other airlines, though, United's offerings aren't great.

In an effort to understand how airlines compare to each other, the American Customer Satisfaction Index (ACSI) Travel Study 2023-2024, surveyed more than 16,000 people via email between April 2023 and March 2024. From there, it ranked nine major U.S. airlines on a scale of 0-100.

United landed near the bottom came in with a paltry score of 75. It only beat out two other airlines — both of which are notorious for their low fares and no frills: Spirit Airlines and Frontier Airlines.

What's more, is that United Airlines was the only airline of the bunch to drop in the 2024 edition of the survey versus the prior year.

Reasons for the drop in United customer satisfaction scores included the declining quality of the reservation system and low scores for in-flight service.

Reliability

Out of nine U.S.-based carriers, United ranked eighth for on-time performance, according to a 2020 analysis by OAG, a provider of air travel data. United departed or arrived within 15 minutes of its scheduled times only 76% of the time.

When it comes to lost baggage, United ranks in the middle of the pack. A report from LuggageHero that analyzed data from the U.S. Department of Transportation found that United was the 7th worst carrier for lost baggage in 2020 out of 16 U.S.-based airlines.

Based on these metrics, United may not be one of the most reliable airlines in the U.S.

Unique perks of flying United

A great perk of flying United is that it’s a member of the Star Alliance, which means you can earn and redeem award miles on some other well-known airlines, including Air New Zealand, Lufthansa, Swiss Air Lines and ANA.

Additionally, United occasionally offers MileagePlus members the chance to take part in its Mile Play promotion. With Mile Play, you can earn additional miles for taking a certain number of flights in a set period of time (for instance, I was offered 21,000 bonus miles for taking four flights worth $300 or more within a period of a few months).

Who should avoid United Airlines?

Although there are benefits to flying United Airlines, some travelers may want to avoid it, such as:

• Travelers who don't live near a hub. United Airlines currently has eight hubs in the U.S. — in Chicago, Los Angeles, San Francisco, Houston, Denver, Guam, Newark and Washington, D.C. Since flights generally operate through its hubs, the majority of U.S.-based United flights originate, end or pass through one of these locations. If you don’t live near a hub, you may want to try an airline with more flights to and from your city.

• Travelers who want to earn loyalty status based on the miles they fly (instead of the cash they spend). Obtaining status on United Airlines is generally done by earning enough Premier qualifying points. With United, PQP is based on the amount of money you spend on items such as base fares, carrier-imposed fuel charges and preferred seat purchases rather than the distance of miles you fly. As a result, if you’re looking to earn status based solely on flight mileage, you may prefer a different airline.
