# When do airline miles expire?

> **Entwurf.** Dieser Beitrag erfüllt die Redaktionsregel noch nicht vollständig und ist nicht indexiert.

Programmes use three models: expiry after inactivity, expiry a fixed period after each credit, and no expiry at all. Which one applies sits in the programme terms rather than in the app. What matters most is which transactions count as activity, because a redemption does not qualify everywhere.


## At a glance

| Model | Clock runs from | Can be reset | Typical for |
|---|---|---|---|
| Activity rule | the last qualifying transaction | yes, through activity | many airline programmes |
| Fixed period after credit | the date of each credit | no | individual programmes |
| No expiry | not applicable | not applicable | many bank programmes |
| Qualifying miles | end of the qualification period | no | every programme with status |
| Tied to an account | closing the card | only before closing | bank points |

## The three models

A balance of [miles](/en/glossary/mile) 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](/en/glossary/transferable-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](/en/glossary/elite-qualifying-miles)
follow the [qualification period](/en/glossary/elite-qualification) 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](/en/glossary/redeemable-mile) 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.

| | Activity rule | Fixed period |
|---|---|---|
| Clock starts | at the last transaction | at every credit |
| Effect of a small purchase | resets everything | applies to that credit only |
| Effort to preserve | once a year | not possible |
| Risk during a long break | low | high |
| Sensible strategy | plan activity | redeem early |

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](/en/glossary/devaluation) behaves entirely differently. It leaves the balance and
raises the price, while expiry removes the balance, as
[what happens in a devaluation](/en/devaluations) 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](/en/point-value) 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](/en/glossary/redeposit-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](/en/points-transfer) 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](/en/when-points-arent-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](/en/transferable-points) 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.

## Frequently asked questions

### Which expiry models exist?

Three: expiry after a period without activity, expiry a fixed time after each credit, and programmes with no expiry. The model sits in the terms and cannot be inferred from the account display.

### What counts as activity?

Depending on the programme, earning, redeeming or both. Some accept any movement on the account, others only new credits, and that distinction decides whether a balance survives.

### Does a small purchase reset the clock?

In programmes with an activity rule usually yes. Shopping through a partner, card spending or a small redemption all work, and the amount rarely matters.

### Do qualifying miles expire the same way?

No. Qualifying miles belong to a qualification period and end with it regardless of activity. Two clocks run in the same account under different rules.

### Does the programme warn me?

Often yes, by email to the address on file. Relying on it is unwise, because addresses go stale and messages land in promotion folders.

### Can expired miles be recovered?

Some programmes offer reinstatement for a fee within a limited window. There is no entitlement, and the fee makes small balances pointless to recover.

### Do bank points expire too?

Usually not while the account stays open. Closing the card can forfeit the balance immediately, and that is the most common quiet loss.

### Does a transfer help against expiry?

It moves the problem. After the transfer the destination programme's rule applies, where the clock often restarts, but the flexibility is gone.

### Does expiry apply to family accounts?

Every account has its own clock. Pooling balances where permitted prevents a small account from lapsing unnoticed.

### What happens when a programme changes its rules?

Expiry rules change like any other terms. An extension lasts as long as announced, and a tightening reaches balances already in the account.

### Is a poor redemption better than expiry?

Often yes. A redemption at a weak value beats losing everything, as long as what you get is something you actually need.

### How do I keep track?

With a list of programme, balance, model and deadline. Four columns are enough, and one annual check prevents most losses.
