Like many other airlines on the best-of list, United benefits from its size. The line boasts a large fleet of planes and is well-staffed, so if there is a problem with a plane’s mechanics or a cabin attendant misses his or her shift, the airline can act quicker than others to find a replacement.
Timeliness isn't the only advantage United offers. The airline has an industry-leading app for booking and tracking flights and operates multiple hubs in cities such as Newark, Denver, Chicago, Los Angeles and Washington D.C., so you can get to many destinations without having to make multiple stops.
The airline also has an outstanding loyalty program, MileagePlus, which users praise as an easy and effective way to earn and redeem miles for flights and merchandise.
United’s planes are among the most modern and fuel-efficient for U.S. carriers and offer more extra-legroom economy seats than any other airline in North America.
