Fixed vs dynamic award pricing: models compared

How do fixed award charts and dynamic award pricing differ?

A fixed model rests on a published structure: the programme sets how many miles a band, a zone or a segment costs before anyone books, so a given journey keeps the same price while that structure holds. Distance bands and a set number of miles per segment are the two common shapes of such a chart (award chart distance bands, fixed miles per segment). [6]

Dynamic pricing turns that around. Instead of one published number for a whole band, the programme prices awards individually and can move the number up or down, so two awards of the same length need not cost the same. The United MileagePlus rules are written in that discretionary form: United establishes the amount of mileage necessary to redeem each award, and the rules say that amount may be substantially increased or decreased. [6]

A stated chart or a stated approach describes the model a programme applies; it is not a guarantee that every individual award on every route is priced from it, because the same terms leave the mileage for each award open to change and allow restrictions on an award or its redemption to be imposed at any time. [6] This is also why the two models are best compared as descriptions of pricing behaviour rather than as promises about a specific seat. Revenue-based redemption is the case where the mileage price is set per award rather than read off a chart. [6]

For planning, the difference is where the uncertainty sits. A published chart gives you a number to save towards and a price you can compare across routes, while a per-award price has to be checked at the time you want to book. Either way, the figure that counts is the one applied when the award is issued. [6]

Why can an award price change without notice?

The United MileagePlus rules give the programme the right to change the rules, benefits, conditions of participation, Premier qualification criteria and mileage levels at any time, with or without notice, even where a change affects the value of miles or certificates already accumulated. [6]

The rules then list what may happen to an individual award: it may be withdrawn, limited, modified or cancelled, the mileage and cash required and any applicable co-pays may be increased, blackout dates may be added, and the number of award seats available to any or all destinations may be limited. [6] Members are expressly told not to rely on the continued availability of an award or an award level. [6]

The consequence for the comparison is simple: a fixed chart stays fixed only for as long as the programme leaves it alone, and a dynamic price can move between the moment you start looking and the moment the ticket is issued. [6]

What applies whatever the pricing model is?

Taxes and carrier charges. Award tickets may be subject to taxes, fees, tariffs, the operating carrier's contract of carriage, ticket terms and re-accommodation policies. [6] Departure taxes, federal inspection fees, passenger facility charges and other charges may apply, and the person travelling on the award ticket is responsible for paying them. [6]

Changes and cancellations. After an award ticket is issued, a service charge may be imposed for each change or cancellation the member requests. [6] If a cancelled award's miles are returned to the account, that redeposit is subject to a service charge, and some awards are not eligible for a redeposit at all. [6]

Partner awards. Where the award is for travel on an airline partner, the routing and destinations available are determined by the individual partner rather than by the programme whose miles you spend. [6]

Destination validity. An award for travel is valid only to destinations served both when the award ticket is issued and when travel begins, and neither United nor its partners is liable for schedule changes that cancel service to a destination. [6]

Miles and money. Award travel does not earn award miles or Premier Qualifying Credits, and that includes tickets paid for with a combination of miles and money. [6]

Exceptions and limits

• United may prohibit award redemption for any member at its discretion, or where the law requires it, so an award price being published does not by itself guarantee that a given account can redeem. [6]
• If a member does not comply with the published award rules for air travel, United may at its discretion place them on a different flight, seat them in a lower class of service, or deny ticketing or boarding, and no compensation is payable for that action. [6]
• Awards may be issued in the member's own name or in the name of another person, but only for non-commercial purposes. [6]
• Accumulating miles, certificates or status does not give a member vested rights in the programme, its awards or its benefit levels. [6]
• Participation and redemption may be restricted by the laws of some countries outside the United States, and the programme rules are not to be read as overriding those laws. [6]

Frequently asked questions

Does a published award chart lock in the price of an award?

The programme keeps the right to change mileage levels at any time with or without notice, so a chart describes the current structure rather than a fixed contractual price. [6]

Can an award that has been priced still be withdrawn?

Yes. The rules allow any award to be withdrawn and allow restrictions on an award or its redemption to be imposed at any time. [6]

Do award tickets avoid taxes and fees?

No. Award tickets may carry departure taxes, federal inspection fees, passenger facility charges and other charges, and the traveller on the award ticket pays them. [6]

Do miles-and-money bookings earn miles back?

No. Award travel does not earn award miles or Premier Qualifying Credits, including tickets bought with a combination of miles and money. [6]
