Which airline operates the frequent-flyer program called MileagePlus?
Answer
United Airlines
Answer
United Airlines
United Airlines operates the frequent-flyer program called MileagePlus.
MileagePlus rewards members for eligible flights with United and participating partner airlines. Members can earn miles and status credits, then redeem miles for flights, upgrades, and other travel-related benefits.
The program originated as United’s Mileage Plus scheme and later adopted the single-word branding MileagePlus. United is a founding member of the Star Alliance, so the program is closely connected with a large international network of partner carriers.
MileagePlus is sometimes confused with American Airlines’ AAdvantage or Delta Air Lines’ SkyMiles. Those programs serve similar purposes but belong to different major U.S. airlines.
