When do airline miles expire?

At a glance#

The three models#

A balance of miles or points does not expire by feel but by a rule, and in any programme that rule is one of three.

The activity rule is the most common. The balance survives as long as a qualifying transaction happens within a stated period. The fixed period is stricter: each credit expires after its own deadline, whether or not the account is used. No expiry applies mostly to bank points, with one caveat. The balance is tied to the account, and closing the account ends the balance.

The models reward different habits. A traveller who flies twice a year finds the activity rule forgiving, because each trip restarts the clock for the whole balance. The fixed period is indifferent to habits: every credit runs out on its own schedule, however active the account looks, and a busy member can lose old credits while new ones keep arriving.

Neither the size of the balance nor the account display reveals which model applies. The model sits in the terms and only there. The app usually shows a date without explanation, and some programmes display nothing at all while a clock is running.

What counts as activity#

Status credit follows a rule of its own. Qualifying miles follow the qualification period and end with it regardless of activity, and nothing extends them. Two clocks therefore run in one account: one governs the balance you redeem, the other governs status, and they have nothing to do with each other. Mixing them up produces the familiar surprise. The redeemable miles still sit in the account although the status lapsed long ago, or the other way round. Status is earned for a period and ends with it; the redeemable balance follows whichever of the three models the programme uses.

The most important distinction#

Programmes with an activity rule differ in which transactions qualify. Some accept any movement, others only new credits. A member who only redeems in a programme of the second kind does not stop the clock, and the balance shrinks and expires anyway because nothing was earned.

Three questions settle the model completely: is there a deadline, what resets it, and when does it start running? The answers sit in a single sentence of the terms, and that sentence decides the fate of the whole balance, so it comes before every other consideration. Whether the terms speak of account activity or of earning takes two minutes to check, and that one word decides the strategy.

Small transactions with a large effect#

In programmes that accept any movement, minimal transactions suffice. A purchase through a partner, card spending or a small redemption all work. The amount usually does not matter, only that the transaction appears in the account with a date.

Most such transactions take minutes, and one a year keeps a balance of any size alive with no other measures.

The difference shows most over long breaks. A traveller who does not fly for two years but shops through partners regularly keeps the balance in one programme and loses it in the other.

Timing and posting dates#

Credits do not appear instantly. Weeks can pass between a transaction and the posting, more often with partners than with the airline itself, and partner bookings take longest of all. A flight on a partner airline frequently appears weeks later while the deadline keeps running.

Resetting the clock close to the deadline means planning for that delay, since a purchase three days before expiry can post too late. The transaction is only safe once it appears on the programme statement. Everything before that is an intention.

Family accounts can take some of the pressure off. Where pooling is permitted, one account with one clock replaces four accounts with four clocks, and the overview gets much simpler.

Worked example: two accounts, the same period#

Two balances sit untouched for the same length of time. One programme uses an activity rule, the other a fixed period after each credit.

The same precaution helps in one programme and does nothing in the other, and without knowing the model every measure is guesswork. Under an activity rule the effort is minimal. Under a fixed period it does not exist, because nothing can be extended, and the only sensible strategy is to redeem in good time instead of collecting, since every credit carries its own expiry date.

A devaluation behaves entirely differently. It leaves the balance and raises the price, while expiry removes the balance, as what happens in a devaluation describes.

During a long break the gap between the two columns widens. In the activity-rule account one small purchase restarts the clock for everything. In the fixed-period account the oldest credits lapse one after another as their own deadlines arrive, and no purchase rescues them.

Promotions that suspend expiry do happen, but they are temporary and discretionary. Relying on one means planning around a promise nobody made.

Why expiry exists at all#

From the programme’s side, every mile issued is an obligation to provide a seat or a room later. An expired balance is a liability the programme no longer carries, so expiry is part of the calculation, never an oversight. A balance is a promise with conditions, and one of those conditions is time.

Accepting that changes how people collect. A balance gets built for a trip, not held as wealth, as what points are actually worth sets out. When choosing between two programmes, the expiry rule belongs in the comparison: a programme without expiry is worth more over long horizons than one with a better ratio and a short deadline.

One habit follows directly. Whenever a balance crosses the threshold for a redemption you would use, book it. A balance that stays large for years points to a redemption that never happened, not to good management.

When it is not worth keeping a balance alive#

The effort is not worth taking on in these situations:

• With very small balances. When the amount covers no sensible redemption, preserving it costs more attention than it is worth.
• With a fixed period and a distant trip. The clock runs regardless of any activity.
• In programmes without suitable routes. A balance that will never be redeemed is administration without a purpose.
• When the reinstatement fee exceeds the value. Expiry is then the cheaper outcome.
• With several small accounts. Maintaining them consumes hours a year on transactions worth less in total than one good redemption.
• With dormant accounts from old trips. They usually hold remnants from single flights, and the effort to preserve them is out of proportion to the contents.

A transfer can reset a clock too, at the price of flexibility, and how a points transfer works sets out that step. A balance under a fixed period is best treated as perishable: planned in, used up, never hoarded.

What actually prevents expiry#

Three measures work, and together they cost a few minutes a year.

An inventory. Programme, balance, model and deadline in four columns, written once and checked annually. Accounts belonging to travel companions go on the same list, because that is where something lapses unnoticed. The list also shows at a glance where enough sits for a redemption and where a balance has been too small for years, as when collecting points is not worth it shows.

Consolidation. Pooling balances leaves fewer clocks to watch and reaches a sensible redemption sooner.

A fixed appointment. A calendar entry is more reliable than any message from the programme, because it does not depend on an email address still being current.

Setting the routine up takes half an hour. After that expiry stops being a risk and becomes a line in a list checked once a year, which is roughly the attention it deserves. Without it, the usual ending is opening an account after several years, finding a zero, and nobody being able to say when it happened.

Abandoning an account deliberately is a legitimate choice too. A remainder that will never be used costs nothing once nobody watches it any more.

Hotel programmes follow the same logic with different deadlines. There too the question is whether a booking, card spending or a stay counts as activity, and there too the answer sits in the terms.

What happens when you close a card#

Bank points are the special case. They rarely expire with time and frequently expire when the card is closed. Before giving up a card, transfer or redeem the balance first and cancel second, because after closing it is usually unreachable, as how transferable points work describes.

Switching to another card from the same bank can affect the balance too. What matters is whether the points account continues, and that sits in the card terms. Changing bank or issuer works the same way: the points account belongs to the card, and without the card access often ends. Asking afterwards rarely helps, since the balance has been removed from the systems and the terms usually do not provide for reinstatement.

Accounts in a former name carry a risk of their own. After a name change the programme and the identity document no longer match, and the redemption then fails on identity, with expiry playing no part.

The most common mistakes#

• Not knowing the model. One reading of the terms settles it, and the answer holds for years.
• Treating redemptions as activity. Some programmes only count earning, and a redemption there does nothing for the clock.
• Acting too close to the deadline. Posting can take weeks, so a last-minute purchase may arrive after the balance has gone.
• Trusting warning emails. Your own reminder in the calendar does not depend on the programme remembering you.
• Maintaining many small accounts. Consolidate them, or let them go deliberately.
• Closing the card and forgetting the balance. Bank points have to be transferred or redeemed before the account closes.
