United's MileagePlus program dazzled critics in 2018. Global Traveler just named United's MileagePlus program the winner in the category of the Best Overall Frequent-Flyer Program. United's loyalty program has actually earned the honor a total of 15 times. Global Traveler determines its winners each year using a survey that is completed by business and luxury travelers from around the world.

What is the secret behind United's success when it comes to impressing travelers year after year? Survey takers were especially pleased with the way they were able to use award miles in a variety of ways in 2018. That included when purchasing car rentals, hotel rooms and merchandise. United also managed to dazzle travelers with its branded credit cards.

It's no secret that 2018 was a big year for United and its loyalty program. One of the big highlights for the program this year was the introduction of an option that allows customers to earn airline miles when they purchase gas from BP. In addition, the MileagePlusX app saw some enhancements in 2018. Members can now use the app to earn and redeem miles in new ways. United customers saw some upgrades regarding boarding this year as well. Premier members now have even more opportunities to board early.
