United Airlines is one of the largest airlines in the U.S., with a route network spanning the world. The airline offers multiple classes service to customers, several of which include the word "economy" in their name. Economy travelers will naturally be wondering what the differences are among United's basic economy, economy and Economy Plus classes — and whether those differences matter enough to pay more for a higher class of service.

The differences extend beyond legroom. Let’s take a look at the features of United economy brands, including seats, fare restrictions and checked baggage limits. If you’re still undecided, use our calculator below to help you decide whether an economy or basic economy ticket is best for you.

Even though there are three classes with economy in the name, there are plenty of differences between them.
