Airline Mile Programmes: A Reference of US Carrier Loyalty Maths

An airline mile is a unit of account within a single airline's loyalty programme. The mile is not a currency in the financial sense; it has no legal tender status, no fixed exchange rate, no guarantee against devaluation. The airline reserves the right to change earning ratios, redemption rates, and award availability without notice in nearly all programme terms.

Mile value is determined entirely by the airline's pricing of award flights against cash. The cardholder values a mile at whatever cash flight cost the mile can offset. For programmes with dynamic award pricing, this varies redemption to redemption. For programmes with fixed award charts (rare in 2026), the relationship is more stable.

Typical mile values, derived from broad redemption-rate analysis across multiple points-and-miles publications:

• Southwest Rapid Rewards: 1.3-1.4 cpp (most predictable, revenue-based on both earn and redemption sides)
• Delta SkyMiles: 1.0-1.3 cpp (dynamic pricing, often below 1.0 cpp on premium routes)
• United MileagePlus: 1.0-1.5 cpp (mixed: Saver Awards at 1.5+ cpp, dynamic pricing at 0.8-1.2 cpp)
• American AAdvantage: 1.4-1.7 cpp (Saver Awards still useful)
• Alaska Mileage Plan: 1.5-2.0 cpp (strong partner award chart preserved)
• JetBlue TrueBlue: 1.2-1.5 cpp (revenue-based; Mint long-haul stands out)

These are typical, not guaranteed. Specific redemptions can fall well outside these bands in either direction.

The general rule we apply across this site: airline miles are worth less than the cardholder's opportunity-cost cash, on average. The mile is best deployed when the cardholder would have flown the route anyway and the mile redemption produces materially better value than the cash purchase. Holding miles speculatively in expectation of future high-value redemption typically loses to investing the equivalent cash; programmes devalue too frequently for hold-strategies to work.

The major US carriers have all transitioned to revenue-based earning over 2014-2018, where miles earned per flight are determined by the ticket price (not the flight distance). Typical structure: 5 miles per dollar for general members, scaling to 8-11 miles per dollar for top-tier elite members.

The shift hurt the original target market of cheap-flight frequent flyers (who earned distance-based miles on rock-bottom fares) and benefited high-fare leisure and business travelers (who now earn proportionally more on expensive tickets). This made airline programmes less generous for the average travel hacker but more generous for the median paying customer.

Distance-based earning persists in narrow partner-side scenarios. Flying Star Alliance partner airlines on a paid ticket allows the cardholder to credit miles to any partner programme; many partner programmes still use distance-based crediting at percentage rates set per fare class. A high-distance, low-fare ticket might earn substantially more miles via partner crediting than via the operating carrier's own revenue-based programme.

For credit card spend specifically, the earn rates are set by the card issuer separately from the airline's in-flight earn structure. Co-branded cards (Delta Gold, Citi AAdvantage, United Explorer) earn 1-2 miles per dollar on most spend with bonus multipliers on direct-airline purchases. Transferable points cards (Sapphire, Platinum, Venture) earn 2-4 points per dollar across categories with the points then transferable to airline programmes at 1:1 (per our transferable vs co-brand discussion).

American Airlines AAdvantage is the largest US carrier loyalty programme by membership. The programme retains a partially-fixed Saver Award chart for redemptions on AA-operated flights and partner airlines, even as it has shifted some redemptions toward dynamic pricing.

Earning structure (per the AAdvantage terms): general members earn 5 base miles per dollar, scaling to 11 base miles per dollar for ConciergeKey (top-tier elite). Loyalty Points (the elite-status qualification metric) are earned 1:1 from base miles.

Redemption structure: Saver Awards on AA-operated flights start at 12,500 miles one-way for short-haul economy domestic, 25,000 miles one-way for cross-country, 30,000-40,000 miles one-way for transatlantic economy, 57,500 miles one-way for transatlantic business class. Partner awards on Oneworld carriers (Cathay, Qatar, Iberia, British Airways, Japan Airlines, Qantas, Royal Jordanian) use a separate chart that has historically offered the programme's best value.

Sweet spot: Qatar Qsuites business class transatlantic, redeemable at 70,000-75,000 AAdvantage miles one-way against cash fares typically $4,000-7,000. The cpp value on this redemption alone reaches 5-9 cpp, well above the programme's 1.4-1.7 cpp typical floor.

Acquisition: AAdvantage miles are not transferable from Chase UR, Amex MR, or Capital One Miles directly. They are reachable via Bilt at 1:1 (a unique partnership) or via earn on Citi AAdvantage co-branded cards, Barclays AAdvantage cards, or paid AA flights. The lack of major transferable-points access has made AAdvantage a more difficult currency to accumulate, valuable for the few who do.

United MileagePlus is the Star Alliance flagship US carrier programme. It uses revenue-based earning (5 base miles per dollar for general members, scaling to 11 for Premier 1K elite) and a mix of fixed Saver Awards and dynamic pricing on award redemptions.

Saver Awards on United-operated flights start at 8,000 miles for short-haul economy. Cross-country starts at 12,500 miles. Transatlantic economy starts at 30,000 miles. Premium-cabin Saver Awards (Polaris business class transatlantic) start at 60,000 miles one-way, when available.

Saver Award availability has tightened over 2020-2026 with United releasing fewer Saver inventory slots in favour of higher dynamic pricing. The result: cardholders often see redemptions priced at 40,000-80,000 miles for routes that historically would have been 30,000.

Acquisition: United is the headline Chase UR transfer partner at 1:1 (per our UR page) and a Bilt Rewards transfer partner at 1:1 (per our Bilt page). United is not directly reachable from Amex MR or Capital One Miles; cardholders in those ecosystems access United via Aeroplan (Star Alliance partner at 1:1 from MR and Capital One) or Avianca LifeMiles (1:1 from MR and Capital One).

The partner-side mechanic for United awards via Aeroplan or Turkish Miles&Smiles often produces substantially lower mileage costs than United's own pricing. A short-haul United domestic flight pricing at 12,000 MileagePlus dynamic might cost 7,500 Turkish miles for the same itinerary. Cardholders who learn the partner-side mechanics frequently bypass MileagePlus pricing entirely.

Delta abandoned its published award chart in 2015 and now uses fully dynamic award pricing on Delta-operated flights. Per the SkyMiles programme rules, awards are priced based on demand at the time of booking. There is no published chart of award costs.

The practical implication: SkyMiles redemptions are often near 1:1 with cash dollars (approximately 1.0-1.3 cpp), behaving more like a 1 percent cashback equivalent than a sweet-spot programme. Delta has used the dynamic pricing flexibility to increase award costs over time, particularly on premium-cabin international routes where partner-airline alternatives are weak.

Earning structure: 5-11 miles per dollar on Delta-operated flights depending on elite tier. Co-branded card structures (Delta Gold, Platinum, Reserve) earn 2-3 miles per dollar on Delta purchases and 1 mile per dollar elsewhere.

Acquisition: Delta is the only major US carrier directly partnered with Amex MR (1:1 transfer). Delta is also reachable via Air France-KLM Flying Blue partner awards (Flying Blue is itself a 1:1 transfer partner of Chase UR, Amex MR, and Capital One Miles). For cardholders with Flying Blue miles, Delta awards via Flying Blue often price better than direct SkyMiles pricing on the same routes; the partner-side mechanic again bypasses the dynamic pricing.

Sweet spot: Virgin Atlantic Flying Club redemptions on Delta. Virgin Atlantic is an Amex MR (1:1), Chase UR (1:1), and Capital One Miles (1:1) transfer partner; Virgin's award chart on Delta routes is fixed and often well below Delta's dynamic pricing. A short-haul Delta domestic might cost 7,500 Virgin Atlantic miles versus 15,000-25,000 SkyMiles dynamic.

Southwest Rapid Rewards is the most predictable programme in the US market because redemption pricing is directly tied to cash fare. The redemption-rate-to-cash relationship is approximately 1.4 cpp consistently, with minor variation by booking class.

Per the Rapid Rewards programme rules, points are earned at 6 points per dollar on Wanna Get Away (basic) fares, 10 points per dollar on Anytime fares, and 12 points per dollar on Business Select. The mechanic ties earn directly to fare class purchased.

Distinctive features:

• No blackout dates. Any seat available for sale at any price is available for award redemption at the proportional points cost.
• Cancellation without penalty. Award redemptions cancel for free, with miles returned and the $5.60 per segment in taxes refunded.
• Companion Pass. Earn 135,000 qualifying points in a calendar year (welcome bonus points count) or fly 100 segments to designate one companion who flies free for the rest of the current year and all of the next year. The most cardholder-friendly programme mechanic in the US market.
• No premium cabin. Southwest operates single-cabin economy on all flights. Award redemptions are all economy class; no business-class sweet spots exist.

Acquisition: Southwest is a 1:1 transfer partner of Chase UR (the only major transferable-points partnership). Reachable also via Chase Southwest co-branded cards.

Alaska Mileage Plan has historically had the best partner-airline award chart in the US market. The programme uses distance-based earning on Alaska-operated flights (still, after most US carriers moved to revenue-based) and offers exceptional partner redemption rates on Cathay Pacific, Japan Airlines, Qantas, Singapore, and several other partners.

Per the Alaska Mileage Plan programme, the partner award chart pricing structure has remained relatively stable since 2018, with periodic adjustments. Sweet-spot redemptions:

• Cathay Pacific business class transpacific (US to Asia): 50,000-55,000 miles one-way against cash fares typically $4,000-6,000 (cpp value 7-12 cpp)
• Cathay Pacific first class transpacific: 70,000 miles one-way against cash fares typically $20,000+ (cpp value approximately 30 cpp)
• Japan Airlines first class transpacific: 70,000 miles one-way against similar premium cash fares
• Qantas business class US to Australia: 55,000-70,000 miles one-way against $5,000-8,000 cash (cpp value 7-15 cpp)

The Cathay Pacific first class redemption (70,000 Alaska miles for a one-way premium cabin) is widely regarded as the single best transferable-equivalent value in the US market, despite Alaska itself not being a major transferable-points partner.

Acquisition: Alaska is a 1:1 transfer partner of Bilt Rewards (per our Bilt page), the only major transferable-currency partnership. Alaska is reachable via Mileage Plan co-branded cards (Bank of America Alaska Visa) or paid Alaska flights.

The accumulation challenge is real: cardholders without Bilt access or BofA Alaska card access can struggle to build large Alaska balances. Buying Alaska miles during periodic promotional discounts (occasional sales at 1.97 cpp per mile) is a known mechanic for capturing the premium-cabin sweet spots.

JetBlue TrueBlue uses revenue-based earning (3 base points per dollar for general members, scaling to 9 base points per dollar for Mosaic 4) and revenue-based redemption. The redemption-rate-to-cash relationship is approximately 1.3-1.5 cpp consistently, similar to Southwest's predictable model.

Per the TrueBlue programme rules, the points-to-cash conversion is published transparently in the booking flow.

Distinctive features:

• Mint long-haul redemptions. JetBlue's Mint business class on transatlantic routes (New York to London / Paris / Amsterdam) prices at approximately 1.3-1.5 cpp on redemptions. For a $2,500 cash Mint fare, the redemption is typically 170,000-200,000 TrueBlue points.
• Mosaic elite (after 50 qualifying segments) provides revenue-based earning bumps and other benefits.
• Family pooling. Up to 7 TrueBlue accounts can pool points into a single household account for redemption purposes, instant and free.
• No blackout dates. Similar to Southwest.

Acquisition: JetBlue is a 1:1 Chase UR transfer partner, 1:0.8 Amex MR transfer partner (the unfavourable ratio), and a Citi ThankYou Points transfer partner. The Chase UR transfer is the cleanest path.
