Elite Qualification Comparison
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.
Southwest Rapid Rewards
Southwest uses Tier Qualifying Points (TQP) for A-List status: 20,000 TQP or 25 qualifying one-way flights for A-List, 40,000 TQP or 50 flights for A-List Preferred.
The Companion Pass requires 135,000 qualifying points in a calendar year. Credit card sign-up bonuses count: the Southwest Priority card bonus (typically 60,000-80,000 points) gets you halfway there. Some travelers open two Southwest cards to hit it from bonuses alone.
Upgrade Instruments
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.
Southwest Rapid Rewards
- Business Select
- Southwest doesn't have cabin upgrades, but Business Select fares guarantee A1-A15 boarding (first on the plane = best seats), a premium drink, and 12x earning. It's the closest thing to a premium cabin.
- EarlyBird Check-In
- Automatic check-in before general boarding for $15-$25 per segment. Gets you a better boarding position without A-List status.

- 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.

- Southwest's cheapest fares redeem at 1.3-1.5 cpp. Sale fares can push value even higher. No blackout dates means the pricing you see is the pricing you get.
- Hawaii from West CoastWanna Get Away · 8,000-15,000 points one-way

Credit Card Strategy
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.
Southwest Rapid Rewards
Southwest Priority card ($149/year) offers 7,500 anniversary points, 4 upgraded boardings per year, and $75 Southwest travel credit. The anniversary points alone are worth ~$100.
Chase Sapphire Preferred or Reserve: transfer Chase UR points 1:1 to Southwest. Chase points transferred to Southwest count toward the Companion Pass threshold.
