Airline miles are a currency whose issuer sets the rate

What follows is an argument about frequent flyer points, and about where the received version of it stops being true.

You are holding someone else's promise

Points are issued by the airline, redeemed against inventory the airline controls, and priced at rates the airline sets unilaterally. No consumer protection generally attaches to their value, and programme terms typically reserve the right to change rates at any time. Devaluations are routine across the industry and have historically arrived with limited notice.

The practical conclusion is to earn and burn rather than to accumulate a large balance indefinitely.

Value is set by the redemption, not the balance

The only meaningful measure is the cash price of what you redeem divided by the points spent, which gives a value per point for that specific transaction. That figure varies by an order of magnitude between a poor redemption and a good one within the same programme.

Long-haul premium cabins usually give the highest value because the cash prices are high; short-haul economy usually gives the worst. Calculating it takes seconds and prevents spending a large balance on a redemption worth less than a cash fare.

Fixed charts and dynamic pricing

Programmes with published award charts let you plan, because the points required for a route are known in advance. Many programmes have moved to dynamic award pricing linked to the cash fare, which removes the possibility of a bargain by design. Where a partner airline still uses a fixed chart, redeeming through that partner can cost far fewer points for the same seat.

Understanding which partner charges what for a given flight is where most of the remaining value in loyalty programmes sits.

Taxes and surcharges

Award tickets still attract government taxes and airport charges, and some airlines add substantial carrier-imposed surcharges on top. On certain routes those surcharges approach the cost of a cheap cash ticket, which makes the redemption poor regardless of the points price. Some partner programmes do not pass on those surcharges, which is another reason to check where to redeem rather than defaulting to your own programme.

Always compare the total cash outlay plus points against the plain cash fare.

Status is a different product

Tier status delivers lounge access, baggage allowance, priority and better disruption handling, which are consumed rather than banked. Status is generally earned on money spent or on qualifying segments and is separate from redeemable points.

For a frequent traveller, status is usually worth more than the points, because it improves every journey rather than paying for one. Chasing status on flights you would not otherwise take rarely pays for itself.

Border and customs rules are national and are the ones worth double-checking.

Practical handling

Points expire in many programmes after a period of inactivity, and a small qualifying transaction usually resets the clock. Transferring points between programmes generally loses value, and transferring from a flexible bank currency into an airline is normally irreversible. Family or household pooling exists in several programmes and is the cleanest way to combine small balances.

From the queue, treat a balance as a use-it-soon asset with a declining exchange rate, because historically that is what it has been.

The takeaway

Value every redemption in cash per point, and treat the balance as perishable.

Pack for the trip you are actually taking, not the one in the photographs.
