Airline miles can expire depending on the airline’s frequent flyer program, and losing a stockpile of hard-earned points because of an overlooked inactivity deadline is one of the easiest travel mistakes to prevent. Whether you fly weekly for work or save your miles for one major trip a year, understanding each program’s rules can protect thousands of dollars in potential value. This guide breaks down every major airline’s mileage expiration policy for 2026, covers credit card and hotel points, and gives you concrete steps to keep your balances safe.
Key Takeaways
- Some airlines have completely eliminated expiration dates for their miles. Airlines like Delta Air Lines and United Airlines do not let miles expire, and programs such as Southwest Rapid Rewards, JetBlue TrueBlue, Alaska Mileage Plan, Aeromexico Rewards, and Virgin Atlantic Flying Club follow the same approach-miles do not expire as long as your account remains open.
- Miles with American Airlines AAdvantage expire after 24 months of inactivity. Air Canada Aeroplan points expire after 18 months of inactivity. Air France/KLM Flying Blue enforces a 24-month rolling window. Avianca LifeMiles expire after 12 months of inactivity. Many Asian and Middle Eastern carriers use hard 36-month deadlines that do not reset with activity.
- Most major credit card points-Chase Ultimate Rewards, Amex Membership Rewards, Capital One miles, Citi ThankYou-do not expire while your account is open and in good standing. However, once you transfer points to an airline or hotel program, they become subject to that program’s expiration policies.
How Airline Miles Expiration Works in 2026
Do airline miles expire? Some do, while others can remain in your account indefinitely. It depends entirely on the airline’s expiration policies and your account activity. Some frequent flyer programs have eliminated expiration altogether, while others enforce strict timelines that can wipe out an entire balance if you aren’t paying attention. Inactivity-based expiration is common for airline miles, and expiration periods for miles may range from 12 to 36 months of inactivity depending on the carrier.
Frequent flyer programs let you earn miles through flying, co-branded credit card spend, partner hotel stays, shopping portals, and dining programs. How you accrue miles matters because many programs treat earning and redemption activity as qualifying activity that resets the expiration clock.
There are three main models for airline mile expiration policies:
- No expiration – Miles remain in your frequent flyer account indefinitely as long as your account stays open. No periodic activity required.
- Inactivity-based expiration – Miles expire after a set window (typically 12–36 months) of no qualifying account activity. Any eligible earn or redeem event resets the timer.
- Hard expiration – Each batch of miles earned has a fixed expiration date (often 36 months from issuance) that does not reset regardless of subsequent activity.
U.S. airline programs have largely moved toward no-expiration policies, while many international loyalty programs and hotel rewards programs still allow points to expire.
Airline Miles That Never Expire (Best-Case Programs)
Several major U.S. carriers and international airlines have adopted policies where miles do not expire, making them particularly attractive to travelers who want to build balances toward high-value Business or First Class redemptions.
As of 2026, these frequent flyer programs do not expire miles due to inactivity, assuming accounts remain open and in good standing:
- Delta SkyMiles – Delta SkyMiles do not expire regardless of account activity.
- United MileagePlus – United eliminated its former 18-month expiration rule in August 2019; United Airlines miles never expire.
- Southwest Rapid Rewards – Southwest Rapid Rewards points never expire under any circumstances.
- JetBlue TrueBlue – Points do not expire with account activity.
- Alaska Atmos Rewards – Following the Alaska/Hawaiian merger, Alaska Mileage Plan miles do not expire, no activity needed.
- Aeromexico Rewards – Miles are not subject to inactivity-based forfeiture.
- Virgin Atlantic Flying Club – Points do not expire.
With these airlines, you don’t need to create periodic activity simply to keep your frequent flyer miles alive. Accounts can still be closed for fraud, abuse, or sanctions, but normal members face no miles expiration risk.
Major Airlines Where Miles Still Expire
Outside the U.S., and even with certain North American carriers, airline miles expire either after a period of account inactivity or according to a fixed timeline from the date they were earned. Some international airlines enforce fixed expiration deadlines regardless of account activity, making it especially important to understand each major airline’s policy before leaving a balance untouched.
Key examples (policies current as of mid-2026; always verify directly with the airline):
- American Airlines AAdvantage – AAdvantage miles expire after 24 months of no qualifying activity. Members under 21 and primary holders of an AAdvantage co-branded credit card are exempt.
- Frontier Miles – 12 months of no qualifying earning activity triggers expiration, making this one of the strictest U.S. mileage expiration policies. Holding the Frontier Airlines World Mastercard keeps miles active.
- Air Canada Aeroplan – Air Canada Aeroplan points expire after 18 months of inactivity; any earning, redeeming, or partner transaction resets the clock.
- Air France/KLM Flying Blue – Under a simplified policy effective May 4, 2026, Flying Blue miles expire after 24 months without eligible activity. Elite status and co-branded card holders may be exempt.
- Iberia Plus – Avios expire after 36 months of no earning or redemption activity.
- Avianca LifeMiles – Avianca LifeMiles expire after 12 months of inactivity.
Some carriers-such as Singapore KrisFlyer and ANA Mileage Club-use hard expirations where miles expire 36 months after they are earned, per tranche, and the clock does not reset with activity (unless you hold PPS Club status or equivalent). This is crucial for long-term planners who accumulate miles slowly.
When you miss these windows, expired miles are typically permanently lost unless reinstatement is allowed for a fee.
Snapshot: Popular U.S. Programs and Their 2026 Expiration Rules
Below is a quick-reference table covering every major U.S. frequent flyer program’s current mileage expiration policy. Use it as a starting point, but always confirm the latest rules on the airline’s website, as expiration policies can change.
Airline Program | Miles Expire? | Inactivity Window | Key Exemptions |
|---|---|---|---|
Delta SkyMiles | No | N/A | Delta miles never expire; account closure for violations only risk |
United MileagePlus | No | N/A | United MileagePlus miles persist indefinitely since 2019 |
Southwest Rapid Rewards | No | N/A | Southwest Rapid Rewards points never expire under any circumstances |
JetBlue TrueBlue | No | N/A | JetBlue TrueBlue points do not expire with account activity |
Alaska Atmos Rewards | No | N/A | Miles do not expire; accounts idle 24+ months may be locked but miles remain |
American Airlines AAdvantage | Yes | 24 months of inactivity | Members under 21; primary AAdvantage credit card holders; reactivation of expired miles possible within 24 months for a fee ($60–$2,000) |
Frontier Miles | Yes | 12 months (earning only) | Frontier Airlines World Mastercard activity keeps miles from expiring |
For Delta business class and United Polaris flyers, the no-expiration rules make these programs especially low-maintenance ways to accrue miles toward premium cabin awards.
International Airlines and Their Mileage Expiration Policies
Most international airline loyalty programs do impose mileage expiration, and policies differ widely between regions. If you’re transferring credit card points to an international partner for a high-value premium-cabin redemption, understanding each program’s rules is essential before making the transfer.
Current timelines by program:
- Air Canada Aeroplan – 18 months of inactivity; any earning, redeeming, or transferring resets the expiration clock.
- Air France/KLM Flying Blue – 24 months without eligible activity. The May 2026 overhaul by Air France KLM unified all miles under a single expiration clock, regardless of how they were earned.
- Iberia Plus – Avios points expire after 36 months of no earning or point redemption activity.
- Emirates Skywards – Miles generally expire approximately three years after they’re earned, at the end of the member’s birthday month-a hard expiration unless you hold elite status or certain rewards card products.
- Singapore KrisFlyer – Miles expire 36 months after earning (hard expiry per tranche). PPS Club members are exempt. Limited paid extension options exist for expiring (not yet expired) miles.
- ANA Mileage Club – 36-month hard expiration on award miles. Million Miler members and certain elite tiers can receive non-expiring balances.
- Turkish Airlines Miles&Smiles – Turkish Airlines miles generally follow a rolling inactivity window, though rules vary by tier.
For KLM business class routes through Europe, the simplified Flying Blue policy makes balances easier to manage, although you still need at least one qualifying activity every two years to keep miles earned through the program active.
Do Credit Card Points and Miles Expire?
Bank credit card points from issuers such as American Express, Chase, Capital One, and Citi behave differently from airline miles. They usually don’t expire as long as your account is open and in good standing. This makes flexible credit card rewards one of the safest places to store travel value long-term.
Credit card points expire only if:
- You close the last card linked to that rewards currency (for example, canceling all your Chase Ultimate Rewards cards).
- The bank closes your account for nonpayment, fraud, or misuse.
Specific programs that persist indefinitely with an open account: Amex Membership Rewards, Chase Ultimate Rewards, Capital One miles, and Citi ThankYou Points.
The critical distinction: once you transfer points to an airline or hotel program, those transferred miles become subject to that program’s rules and can then expire like normal frequent flyer miles. If you transfer 50,000 Chase points into Singapore KrisFlyer, those miles now face a 36-month hard expiration date. The safest approach is to keep credit card points in your bank account until you’re ready to redeem points for a specific booking-then transfer and book immediately.
Do Hotel Points Expire? (And How That Affects Airline Strategy)
Unlike many U.S. airline miles, nearly all major hotel loyalty programs still enforce expiration rules tied to inactivity. Here’s how hotel points expire across the biggest chains:
Hotel Program | Expiration Rule |
|---|---|
Marriott Bonvoy | 24 months of no qualifying activity |
Hilton Honors | 24 months of inactivity |
IHG One Rewards | 12 months for base members; elite members’ points don’t expire |
World of Hyatt | 24 months of inactivity |
Wyndham Rewards | 4-year hard expiration per point plus 18-month inactivity rule |
Hotel activity-stays, co-branded card spend, buying miles, donating miles, and some partner transactions-usually resets the expiration clock. Elite status can provide exemptions in several programs.
This matters for airline strategy because travelers often transfer credit card points to hotels or airlines. Once transferred, those points can expire according to each partner’s mileage expiration policy, rather than the flexible bank rules they originally followed.
Practical Ways to Keep Miles and Points From Expiring
In most airline programs where miles expire, resetting the timer is relatively easy and inexpensive. You rarely need to book a flight, as qualifying activity can be as simple as making a purchase through an airline shopping or dining portal.
Concrete actions to keep miles active and prevent airline miles from expiring:
- Hold and use a co-branded airline credit card for small regular purchases. Holding a co-branded credit card prevents miles from expiring in programs like American Airlines AAdvantage and Frontier Miles.
- Credit even a short, inexpensive flight to the program before the expiration date.
- Use the airline’s shopping portal or dining program to earn more miles on everyday spending. Even a single purchase can count as qualifying activity and reset the expiration clock.
- Using miles for a small redemption-a magazine subscription, gift card, or low-cost award-resets the expiration clock in most programs.
- Transfer a small batch of points (as few as 1,000) from a bank rewards program to extend your miles in programs that count incoming transfers as qualifying activity.
- Donate miles to a charity partner when allowed by the airline.
- Selling miles is an option before expiration occurs in some programs, though resale values vary.
- Buying miles directly from the airline also counts as account activity in many programs.
Setting reminders to check mileage expiration dates is one of the easiest ways to keep accounts active.Set a reminder 90 days before your inactivity window ends so you have plenty of time to log a qualifying activity without rushing.

Can You Get Expired Miles Back?
Once miles have fully expired, recovering them can be difficult. Miles expired under program rules are typically permanently lost unless reinstatement is available for a fee, and those options are neither universal nor inexpensive.
Programs where reinstatement is possible as of 2026:
- American Airlines AAdvantage – Allows reactivating up to a defined cap of expired AAdvantage miles within 24 months of expiration, for a tiered fee ranging from roughly $60 to $2,000 depending on mileage volume.
- Frontier Miles – May reinstate miles for a fee that scales with balance size.
- Emirates Skywards and select Asian carriers – Offer paid reinstatement per 1,000 miles within a limited window after expiration.
Reinstatement is usually poor value compared with keeping miles active through a low-cost qualifying activity. A $5 shopping-portal purchase that resets the clock can be far better value than paying hundreds of dollars to recover an expired balance. If you realize miles have just lapsed, contact the airline’s customer service immediately-some agents have discretion to help within the first few days.
Planning Ahead: Avoiding Miles Expiration in Your Travel Strategy
Think of your miles and points as a travel portfolio that needs occasional attention, especially when you’re planning premium itineraries across multiple airlines and alliances.
- Audit all loyalty accounts (airline, hotel, credit card) at least twice per year. Check balances, upcoming expiration dates, and whether any program’s rules have changed.
- Use a simple spreadsheet or calendar alerts to monitor when specific balances will expire. Even a quarterly five-minute review can save you from a costly lapse.
- Prioritize using miles that are closest to expiring for upcoming trips. Save non-expiring currencies like Southwest Rapid Rewards points or major bank points for later high-value redemptions.
- Coordinate timing for milestone trips. For honeymoons, milestone birthdays, or important business travel, aligning credit card sign-up bonuses, elite status windows, and expiration dates can significantly expand your cabin and route options.
