American Airlines vs United: 2024 Comparison of Flights, Fees & Loyalty Perks
American Airlines and United Airlines are the two largest U.S. legacy carriers, each offering global route networks, multiple fare classes, and distinct frequent-flyer programs—AAdvantage for American and MileagePlus for United.
Travelers often lump them together because both dominate hubs like Chicago O’Hare and Dallas-Fort Worth. The real confusion hits at checkout: seat maps, bag fees, and upgrade rules shift weekly, so a quick Google shows “United vs American” more than any other airline pair.
Key Differences
United beats American on Polaris business-class bedding and a denser international network, while American wins with more domestic first-class seats and slightly lower domestic change fees. Checked bags start at $35 on both, but United’s basic-economy passengers can bring a full-size carry-on; American’s cannot.
Which One Should You Choose?
If you live near an American fortress hub (DFW, Charlotte, Miami), AAdvantage status is easier to earn. Midwest and West-Coast flyers often find United’s Star Alliance partners give better global upgrades. Compare year-end elite perks: American offers 4 systemwide upgrades at Platinum Pro, United gives 4 PlusPoints at Premier 1K—pick based on where you actually fly.
Examples and Daily Life
Imagine a Tuesday business trip: American’s 7 a.m. DFW–LAX has Wi-Fi that works gate-to-gate, while United’s 8 a.m. IAH–LAX offers more legroom in Economy Plus for the same price. At landing, United’s app pings you a free same-day change, American’s gives a free snack voucher—small perks that shape loyalty.
Do both airlines charge for seat selection?
Yes, basic-economy fares on both lock seats at check-in; paid selection starts around $9 on short hops.
Which program lets families pool miles faster?
United’s MileagePlus allows free pooling for up to 5 members; American requires co-branded credit cards to share miles, adding cost.
