Before you ask which airline program is best, there is a more important question: where should your points be sitting right now?
Leave them in the card portal until you are ready to book
If your points are in Chase Ultimate Rewards, Amex Membership Rewards, Capital One Miles or Citi ThankYou Points, leave them there. Do not move them into an airline account “just in case,” and do not move them because you read that a particular program is the best one.
Four reasons this matters more than almost anything else in this hobby.
Transfers are one way. Move 50,000 Chase points into United MileagePlus and they are United miles forever. Find a better redemption on a different airline next week and you are stuck.
Award pricing changes. Delta and United both use dynamic pricing, so the miles a flight costs today may bear no relation to what it costs in three weeks. Transferring in advance locks you into whichever program you guessed right about, with no way back.
Card points are more flexible than any airline’s miles. A point in your Chase account can become United miles, Hyatt points or Flying Blue miles depending on what you need when you need it. That same point in a United account can only ever be a United mile.
Transfer bonuses come and go. Issuers run 25 to 40 percent bonuses on specific partners for a few weeks at a time. Sitting on your balance lets you catch one instead of transferring at a flat rate out of habit.
The only exception: once you have found the exact award you want and you are worried the space will vanish, transfer immediately before booking. Not months ahead.
Treat the card portal like a savings account and your airline balance like a checking account you top up right before you spend it.
So when you do transfer, where should it go?
That depends on the pecking order. Below is my honest ranking of the major U.S. airline programs, judged on how far the miles actually take you, the partner network, expiration rules and real world redemption value. Not the sticker price of a flight.
| Program | Typical value | Expiration | Best for | |
|---|---|---|---|---|
| 1 | Atmos Rewards | 1.4 to 1.55¢ | Never | Highest value, partner awards |
| 2 | American AAdvantage | 1.4 to 1.6¢ | 24 months inactivity | International premium cabins |
| 3 | United MileagePlus | 1.3 to 1.5¢ | Never with activity | Global reach |
| 4 | Southwest Rapid Rewards | 1.25 to 1.4¢ | Never | Domestic simplicity |
| 5 | JetBlue TrueBlue | ~1.35¢ | Never | East Coast Mint value |
| 6 | Delta SkyMiles | ~1.2¢ | Never | Elite experience, not value |
1. Atmos Rewards (Alaska + Hawaiian)
Value: roughly 1.4 to 1.55 cents per mile · Expiration: never · Partners: strong Oneworld access plus unique sweet spots
Atmos is the combined Alaska and Hawaiian program, and it takes the top spot for one reason: your miles go further here than almost anywhere else. Awards start as low as 4,500 points one way within North America, and Alaska has always been unusually generous on partner redemptions, so you can fly Cathay Pacific, Japan Airlines and Qantas on miles from an airline that flies none of those routes itself.
That is the thing worth understanding. Value is not about how many destinations an airline serves. It is about how many destinations your miles unlock through partners, and Atmos does that better than anything else on this list. Miles never expire, so there is no pressure to burn them on a poor redemption just to keep them alive.
Best for: anyone wanting high value and flexibility, particularly West Coast travellers and people chasing international partner awards.
2. American AAdvantage
Value: roughly 1.4 to 1.6 cents per mile · Expiration: 24 months of account inactivity · Partners: excellent Oneworld network
American the airline gets a rough press. AAdvantage the program is a different matter, and it sits second on a similarly strong Oneworld network with one meaningful catch: miles expire after 24 months of complete inactivity. Easy to avoid if you hold a co-branded card or fly occasionally. A real risk for someone who signs up, earns a bonus and walks away.
What makes AAdvantage genuinely valuable is how it prices international premium cabins. Business and first class on partners like Qatar and Japan Airlines can return 3 to 5 cents per mile or more. Add the status boosts available through Citi’s AAdvantage cards and it rewards both casual earners and someone chasing one specific bucket-list seat.
Best for: international premium cabin awards and steady domestic value.
3. United MileagePlus
Value: roughly 1.3 to 1.5 cents per mile, best on partners · Expiration: never with some activity · Partners: the largest network in the world
United drops to third not because it is bad but because its own award chart is dynamically priced, so the miles a flight costs swing with demand and value becomes hard to predict.
Where it pulls ahead is reach. Star Alliance is the biggest of the three global alliances, so if your travel goes somewhere unusual, United miles are more likely to get you there than Alaska’s or American’s networks. This is the program for someone who cares more about “can I get anywhere” than about squeezing the last cent out of every mile.
Best for: global travellers who value destination options over maximum value.
4. Southwest Rapid Rewards
Value: roughly 1.25 to 1.4 cents per mile · Expiration: never · Partners: very limited
Southwest sits mid-table for a reason that is a feature rather than a flaw: there is no math to do. Rapid Rewards is revenue based, so points scale directly with the cash price. You will never find a spectacular sweet spot, and you will never get burned by a bad redemption either.
That predictability, plus two free checked bags and the Companion Pass, makes this the easiest program to understand for someone flying mostly domestically who has no interest in studying award charts. The trade is that with no partner network, you are capped at whatever the cash fare would have been.
Best for: families, frequent domestic flyers, and anyone chasing the Companion Pass.
5. JetBlue TrueBlue
Value: roughly 1.35 cents per mile, notably better on Mint · Expiration: never · Partners: limited
A niche pick with a narrow but genuine strength. Live near a JetBlue hub on the East Coast and want an affordable route into Mint business class, and this delivers value that rivals much bigger programs.
Outside that specific case the partner list is thin, so it offers little flexibility when plans change or take you somewhere JetBlue does not fly. An excellent second program. A poor only program.
Best for: East Coast travellers wanting an affordable path into a premium cabin.
6. Delta SkyMiles
Value: roughly 1.2 cents per mile · Expiration: never · Partners: SkyTeam, decent but the weakest of the three alliances
Delta lands last, and it is worth explaining why, because Delta is genuinely one of the better airlines to fly.
The problem is not the airline. It is the loyalty math. SkyMiles is fully dynamically priced with no published award chart at all, so prices float with cash fares and the sweet spots that make Atmos and AAdvantage valuable simply do not exist. In practice you are rarely getting outsized value. You are prepaying for a flight in a different currency.
Where Delta still wins is the day to day: a huge domestic network, reliable operations, and strong upgrade odds if you fly enough to hold status. It rewards loyalty and convenience rather than point maximising.
Best for: people near a Delta hub who value the experience and elite upgrades over squeezing every mile.
The international programs where the value actually is
Everything above is a U.S. program. But the best redemptions in this hobby are rarely booked through one.
The programs below are foreign airline loyalty schemes that happen to be transfer partners of American credit cards. You are not “joining” them in any meaningful sense, and you are certainly not keeping a balance in them. You are transferring in at the moment you book, because that particular program prices that particular seat better than anyone else does.
That is the whole game. The airline flying the plane and the program you book through are two different decisions.
Air Canada Aeroplan
Reachable from: Chase, Amex, Capital One
The most broadly useful program on this list. A distance-based award chart means pricing is predictable rather than floating with cash fares, the Star Alliance network is enormous, and Aeroplan does not pass on fuel surcharges on most partner airlines. That last point matters more than people realise, because surcharges are what quietly turn a cheap-looking award into an expensive one.
It also permits a stopover on a one-way award for a small additional charge, which effectively turns one redemption into two trips.
The catch: miles expire after a period of account inactivity, so do not transfer speculatively and then forget.
Air France / KLM Flying Blue
Reachable from: all four major issuers
The most accessible program here, and the one most likely to be reachable regardless of which card you hold. Flying Blue runs monthly Promo Rewards discounting specific routes substantially, which is worth checking before you look anywhere else.
The catch: pricing moves with demand rather than sitting on a fixed chart, and surcharges apply on some routes. Check the total cash cost, not just the miles.
Avianca LifeMiles
Reachable from: Amex, Capital One, Citi
The reason to know LifeMiles is simple: no fuel surcharges on Star Alliance partners. That can be the difference between an award costing you $60 in taxes and one costing $600, on the identical seat.
LifeMiles also runs frequent mile sales, which occasionally make buying miles outright cheaper than transferring.
The catch: the website is unreliable and the customer service is worse. Bookings sometimes fail partway through. Budget patience.
British Airways, Iberia and Aer Lingus (Avios)
Reachable from: all four major issuers
Three programs sharing one currency, and you can move Avios between the accounts. They price the same flights differently, which is exactly why the distinction matters. Iberia in particular prices some transatlantic routes well below what British Airways charges for the same seat.
Avios is distance-based, which makes short-haul flights unusually cheap.
The catch: British Airways passes on substantial carrier-imposed surcharges, especially departing the UK. An Avios award that looks cheap in points can carry several hundred dollars in fees. Always check the cash component before transferring.
Virgin Atlantic Flying Club
Reachable from: Chase, Amex
Worth knowing specifically for partner redemptions rather than for flying Virgin. The program has historically priced certain partner premium cabins far below what those airlines’ own programs charge.
The catch: surcharges on Virgin’s own metal are heavy, and the partner sweet spots that make this program interesting have been repriced more than once. Verify current pricing rather than relying on any article, including this one.
Singapore Airlines KrisFlyer
Reachable from: all four major issuers
The only way to book Singapore’s own premium cabins reliably. Singapore releases limited award space on its best products to partner programs, so if you want Singapore business or first, you generally book through KrisFlyer directly.
The catch: availability on the flagship routes is genuinely scarce and often needs booking the moment the schedule opens.
ANA Mileage Club
Reachable from: Amex
A narrow program with a specific strength: ANA has historically priced its own premium cabins low, and the Star Alliance partner chart is competitive.
The catch: most awards must be booked as round trips, which removes the flexibility of mixing programs on the outbound and return.
Turkish Miles&Smiles
Reachable from: Capital One, Citi
Known for pricing certain Star Alliance routes, including short domestic United flights, well below what United itself charges.
The catch: the booking experience is the most difficult on this list. Phone bookings are often required, hold times are long, and the website frequently fails to display availability that exists. The value is real, but you earn it.
Qatar Privilege Club, Emirates Skywards, Cathay Asia Miles, Qantas
Reachable from: varies by issuer
Worth knowing exist, each with narrow strengths. Emirates in particular carries heavy surcharges that erode most of the value on its own metal.
The rule that runs through all of this
Two things decide whether an international program is worth transferring into.
Surcharges. A 60,000 mile award with $700 in carrier-imposed fees is a worse deal than a 75,000 mile award with $80 in taxes, and the miles figure alone will not tell you that. Price the whole booking.
Bookability. A program with a spectacular chart and a website that cannot complete a booking is not actually cheap. It is expensive in a currency that does not show up on the statement.
The honest answer
Match the program to your home airport and how you actually travel. You do not need to be loyal to one. Plenty of people keep balances in two or three depending on where they fly.
And whichever you choose, the first rule still applies: leave the points in your card account until you have the seat in front of you.

Cents-per-mile figures are estimates based on typical redemptions and move over time. Programs change their charts, and several on this list have done so recently.
