Elite Qualification Comparison
American AAdvantage
Everything earns Loyalty Points: flight miles, AAdvantage credit card spending (1 LP per dollar), Amex co-brand spending, shopping portal purchases, SimplyMiles offers, and partner activity. This makes AAdvantage the most 'earnable' status among US carriers if you're willing to optimize across all channels.
The Citi/AAdvantage Platinum Select card earns 2x on AA purchases and gas stations, 3x on eligible American Airlines purchases. The Citi Executive card adds Admirals Club access. Both contribute Loyalty Points from spend.
United MileagePlus
United uses PQF (flights) + PQP (spend), or PQP-only. The dual path matters: if you fly 60+ segments a year, you only need $22,000 PQP for 1K instead of $28,000 PQP-only. That's a $6,000 difference.
Credit card spend contributes PQP: the United Explorer card earns 500 PQP per $12,000 spend. The United Club Infinite card is better at 1,000 PQP per $12,000 spend. The United Quest card earns 500 PQP per $12,000 spent. Stack multiple cards to accelerate qualification.
Upgrade Instruments
American AAdvantage
Systemwide Upgrades (SUWs)
Confirm upgrades to Flagship First/Business on any American-operated route worldwide. The most valuable upgrade instrument in the AA ecosystem. Can be applied at booking or waitlisted. Must be on a qualifying fare class.
500-Mile Upgrades
Legacy upgrade certificates for domestic flights under 500 miles. Less valuable than they once were but still clear on short-haul routes.
Miles + Co-pay Upgrades
Use miles plus a cash co-pay to upgrade on select flights. Available to all AAdvantage members, not just elites. Pricing varies by route and cabin.
United MileagePlus
PlusPoints
United's flexible upgrade currency. Can be used for confirmed upgrades (applied at booking or up to departure) on United-operated flights. Points required vary by route: 20 for domestic, 40 for short-haul international, 80 for long-haul international Polaris. Unused PlusPoints roll over if you requalify at the same tier.
Complimentary Upgrades
Free upgrades to Economy Plus and domestic first/business class. Clears based on status, fare class, and check-in time. 1K clears most domestic flights; Silver may only clear on off-peak routes.
GPU (Global Premier Upgrades)
Systemwide upgrade instruments for international Polaris business class. These are legacy instruments that United has largely replaced with PlusPoints, but some 1K and GS members still receive them.
Best Redemption Sweet Spots
American AAdvantage
US to Middle East (e.g., JFK-DOH)
Qatar Airways Qsuite · 70,000 miles one-way
Qatar's Qsuite is widely considered the world's best business class. Booking with AAdvantage miles at 70K one-way is outstanding value for a product that costs $5,000+ in cash.
US to Japan (e.g., DFW-NRT)
Japan Airlines Business Class · 60,000 miles one-way
JAL's Sky Suites are excellent, and AAdvantage often has better partner availability than booking directly through JAL.
US to Hong Kong/Asia
Cathay Pacific Business · 70,000 miles one-way
Cathay's reverse-herringbone business class is superb. OneWorld partnership means good availability via AAdvantage.
United MileagePlus
US to Japan (e.g., SFO-NRT)
ANA Business Class via Star Alliance · 88,000 miles round trip
ANA's 'The Room' business class is one of the best products in the sky. Booking via United miles on ANA-operated flights can still offer excellent value.
US to Europe (e.g., EWR-FRA)
Lufthansa Business Class · 77,000 miles one-way (dynamic)
Lufthansa's new Allegris business class suite is rolling out in 2025-2026. Book with United miles for access to what will be one of Europe's best business products.
US domestic (e.g., SFO-EWR)
United Polaris / domestic first · 20,000-30,000 miles one-way
On transcontinental routes, United flies wide-body aircraft with Polaris seats. This is lie-flat domestic business class for 20K-30K miles.
Credit Card Strategy
American AAdvantage
Citi AAdvantage Executive card ($595/year) gives Admirals Club access and strong Loyalty Point earning. The Admirals Club benefit alone is worth ~$650/year if you fly AA regularly.
Citi ThankYou Points (via Citi Strata Premier) transfer to AAdvantage at 1:1. This is a recent re-addition and opens up a second earning channel for AAdvantage miles.
United MileagePlus
The United Club Infinite card ($525/year) is the power play: United Club access, 2 free checked bags, 1,000 PQP per $12,000 spend, and 500 PlusPoints per $50,000 spend. The PlusPoints alone make it worthwhile for Platinum+ members.
Chase Sapphire Reserve ($550/year) earns Chase Ultimate Rewards that transfer 1:1 to United. The 3x on travel and dining often yields better earn rates than United's co-branded cards for non-United spending.
