Tracking different airlines’ frequent flyer programs to find the best offers can feel like a full-time job (and indeed, for some travel bloggers, it truly is). Rules keep evolving, miles expire, and earning enough points doesn’t stretch as far as it once did.
For a thorough look at the top U.S. airlines’ programs, this New York Times Frugal Traveler analysis clearly breaks down the key differences.
Airline Partnerships and Alliances
You’re free to sign up for as many frequent flyer programs as you wish, and since most are free to join, it’s a smart move to enroll in several proactively.
Don't forget about international airline alliances, which can offer more value for your travel. These partnerships benefit both carriers: Airlines can redirect passengers to a partner airline instead of a rival, and perks like redeeming miles, enjoying business class, or accessing lounges are often transferable. Regarding major U.S. carriers, United is part of the Star Alliance, American is in One World, and Delta belongs to Sky Team. These alliances are especially useful when flying to various destinations around the country or internationally.
American Airlines
The AAdvantage program of American Airlines requires travelers to accumulate 25,000 qualifying miles and spend 3,000 qualifying dollars to reach its base elite status, Gold. This level comes with benefits such as a free checked bag and seven miles for every dollar spent.
The highest tier, Executive Platinum, necessitates 100,000 qualifying miles and 12,000 qualifying dollars. This level provides a free checked bag and priority boarding.
Delta
Delta’s SkyMiles program offers basic members five miles per dollar spent on Delta flights, with the opportunity to earn more as you progress. Diamond Medallion, the highest status, rewards you with 11 miles per dollar spent, but reaching it requires 125,000 qualifying miles and $15,000 in qualifying dollars.
To achieve Silver status, which is above General status, you must travel 25,000 qualifying miles and spend 3,000 qualifying dollars. This level includes a free checked bag and occasional upgrade opportunities.
One significant advantage of Delta’s program is that SkyMiles never expire, though Times reports that Delta has lowered the value of its points several times without prior notice. Something to keep in mind.
United Airlines
The United Airlines MileagePlus program requires 25,000 qualifying miles and 3,000 qualifying dollars to reach its lowest tier, Silver, which provides a free checked bag and access to Economy Plus seats. To reach the top tier, 1K status, you'll need 100,000 qualifying miles and 12,000 qualifying dollars.
Achieving Gold status, which requires 50,000 qualifying miles and 6,000 qualifying dollars, will grant you Star Alliance Gold status, providing access to lounges worldwide.
