# How do I get upgraded on a flight?

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

An upgrade comes from five routes: buying at booking, buying after booking, a bidding process, redeeming miles or certificates, and an operational move by the airline. Within each route the order is decided by fare, tier and timing rather than by asking politely at the desk.


## At a glance

| Route | Who decides | Timing |
|---|---|---|
| Buying at booking | the traveller | immediately |
| Buying after booking | the airline | until shortly before departure |
| Bidding | the airline | usually one or two days ahead |
| Miles or certificate | award space in the premium cabin | from booking, often late |
| Operational move | the handling agent | as boarding closes |

## Why upgrades are getting rarer

For an airline a higher cabin is a product with a price, and every seat given away is a seat that
was not sold. That calculation explains the whole development of recent years. Where a gate agent
once moved people, a booking portal now shows an offer.

For travellers the question is no longer how to get an [upgrade](/en/glossary/upgrade) but which of the five routes is
open in a particular case. Older advice stopped working for the same reason: it comes from a time
when empty seats were a distribution problem and not yet revenue.

Load adds to it. Premium cabins have become smaller and are sold more precisely, so less stays empty
on the day than a decade ago. And upgrades are now offered in the portal, in the app and at check
in, and each of those points takes seats before any allocation starts.

## The five routes

### Buying at booking

Five routes sound like choice but form a sequence. Buying at booking or afterwards is open to
everybody, miles and bids need a balance or an invitation, and the operational move cannot be
influenced at all.

Buying directly is the only route with certainty. Booking the higher cabin means having it, and the
price is fixed in advance. Comparing still pays, because the premium varies by route and date, and on
routes with little business traffic it occasionally sits below the price of a later upgrade.

For evaluation the difference to the cheapest fare counts, not the gap to the published price.
Separating those two shows quickly whether the premium is worth it.

### Buying after booking

Many airlines offer a fixed price upgrade after booking. The offer appears in the account and moves
with the load.

The price does not reliably fall as departure approaches. With strong demand it rises, and with weak
demand the offer sometimes disappears entirely. Waiting speculates in both directions, and a fixed
price that is acceptable usually beats the prospect of a later one.

Direction matters as well. On many routes the higher cabin costs far more one way than the other,
because demand is unevenly distributed.

### Bidding

In a bidding process the traveller names an amount and the airline decides shortly before
departure. The bid is tested against an internal floor nobody sees. A higher bid improves the chance
and guarantees nothing, and with a sold out cabin every bid comes to nothing.

The process mostly serves the airline. It learns what individual customers will pay and keeps that
knowledge for future pricing.

Before bidding, check the premium of a direct purchase. A bid above that line is the worse route in
every case, because it is uncertain as well. The offer at check in is a special case: it appears hours
before departure and is often cheaper, but it only covers seats nobody bought until then. If the
higher cabin is part of the plan for the trip, book it directly. Everything else is a bet, and the bet
costs more than the premium would have.

### Miles and certificates

A mileage redemption almost always requires a specific [booking class](/en/glossary/fare-class). The cheapest fares are
excluded, and those are the ones most often booked. [Award space](/en/glossary/award-availability) must also exist: an empty seat
is not enough, the airline has to release it for redemptions.

Both conditions together explain why mileage upgrades so rarely work. Certificates from card
programmes carry the same conditions. They behave like [miles](/en/glossary/mile) with a fixed number of uses and fail at
the same two hurdles. What the redemption is worth is calculated in
[what points are actually worth](/en/point-value).

Which booking class qualifies for what sits in the [fare rules](/en/glossary/fare-rules), not in the programme. How those
rules are read is set out in [fare rules](/en/fare-rules).

### The operational move

When the lower cabin is oversold or the aircraft has changed, the handling agent has to move people.
The move solves a capacity problem, and nobody at the desk means it as a gift.

The order exists in the system and follows tier, fare and sometimes check in time. It is not formed
at the desk. An aircraft change can work in both directions: a larger aircraft creates empty seats, a
smaller one removes booked ones, and the move then goes down instead of up.

Two terms get confused here. [Overbooking](/en/glossary/overbooking) concerns the number of seats sold, an aircraft change
the number available, and only the second regularly creates empty seats up front.

## Why the fare often outweighs the tier

Many programmes sort by booking class first and by tier second. An expensive fare without status can
therefore sit ahead of a cheap fare with a high tier. The upgrade is decided when choosing the fare,
weeks before anyone reaches the airport, and the small saving on a cheaper ticket can cost the place
in the queue.

The same logic explains the most common disappointment. A high tier on the cheapest fare gives no
priority where it is expected, as [when status gets you nothing](/en/when-status-gets-you-nothing) shows in detail.

## Worked example: two travellers, one empty seat

One seat stays empty in the higher cabin. Two travellers qualify: somebody with a high tier on the
cheapest fare, and somebody without status on an expensive flexible fare.

| | High tier, cheap fare | No status, expensive fare |
|---|---|---|
| Sorted by booking class | back | front |
| Sorted by tier | front | back |
| Usual position in the system | second | first |
| Chance of being moved | low | higher |
| Perceived fairness | low | high |

The table describes the usual pattern, not any single airline's rule. Knowing it means expecting less
and being annoyed less often.

Sorted by booking class, the flexible fare goes to the front and the high tier waits behind it.
Only a programme that sorts by tier first would flip the order, and many do not. The frequent flyer
on the cheapest fare therefore usually ends up second, watches the seat go to a stranger without
status, and finds the outcome unfair, although the system has done what it was built to do.

The usual position in the system is what counts. The order comes from two criteria, and the first of
them is fixed when the ticket is bought. Accepting that produces better booking decisions; the
alternative is hoping at the airport for a rule that does not exist in that form.

A low chance is not a zero chance, though. On secondary routes operational moves still happen, just
rarely and without announcement.

## What does not work

Three recommendations persist and achieve nothing.

**Asking at the desk.** The list exists before anybody reaches the counter, and staff usually
cannot change it.

**Dressing up.** Selection runs on data, and nobody sees the passenger before the list is set.

**Naming the occasion.** Honeymoons, birthdays and anniversaries change no order, because the
booking system has no field for them.

An empty seat up front does not mean the lounge is open either. The two benefits follow different
rules, as [who gets into the lounge](/en/lounge-access) shows.

## When it is not worth buying an upgrade

Paying for the higher cabin is not worth it in these situations:

- **Short routes.** The difference is mostly [seat pitch](/en/glossary/seat-pitch) and service, and both matter little over
  a short flight.
- **Overnight flights without a flat bed.** Without a real lying position the gain stays small
  while the premium applies in full.
- **When status is sacrificed for it.** Booking a cheaper fare to finance the upgrade often costs
  qualifying points.
- **Bids near the purchase price.** A bid that reaches the premium of a direct purchase is the
  worse route, because it stays uncertain.
- **On the shorter leg of a connection.** An upgrade on the first segment changes nothing about the
  second, and the longer leg is usually the second.
- **With hand luggage only.** A higher cabin often includes extra checked bags, and a traveller
  without a suitcase pays part of the price for a benefit they will not use.

Families are not moved preferentially; if anything the opposite, because seat groups have to stay
together and the higher cabin rarely has enough free seats. Long loyalty to one airline does not
count as a criterion either, because the tier already represents what the company wants to see of
it.

## What helps

A few points improve the chance measurably, and none of them is a trick.

**The fare.** A booking class eligible for redemptions and moves decides more than any tier.

**The timing.** Taking an upgrade as soon as it appears at an acceptable price beats every waiting
strategy.

**The route.** Connections with little business traffic leave more empty seats, and the premium
there is lower. On routes with several daily departures the edges are worth a look: early Saturday
and late Tuesday departures are regularly weaker in the premium cabin than everything in between.

**Flexibility.** Being willing to take an earlier or later flight finds empty premium seats more
often, because demand swings across the day.

Disruption occasionally creates a move too, when a cabin fails or an aircraft is swapped. What
applies then is in [what to do when a flight is cancelled](/en/flight-cancelled-what-to-do).

None of this turns a chance into a certainty, but the chance rises for the reasons the system
recognises. An upgrade today is mostly a purchase and rarely a reward. Buying occasionally and never
planning around hope is the attitude under which the maths works across a travel year: book the
cabin when it is needed, and take a move when it happens.

## The most common mistakes

- **Hoping for an upgrade at the gate.** The list is set before boarding, so a cabin that matters
  gets bought.
- **Ignoring the fare.** The booking class sorts first, which makes it worth checking before
  booking.
- **Waiting for a falling fixed price.** Prices rise with demand as often as they fall, and an
  acceptable offer is best taken when it appears.
- **Bidding without a ceiling.** The premium of a direct purchase is the natural upper limit for any
  bid.
- **Assuming mileage upgrades are easy.** Booking class and award space both have to fit before the
  miles are worth anything.
- **Treating status as a promise.** The tier sorts within the class; it creates no seat.

## Frequently asked questions

### Which routes lead into a higher cabin?

Buying at booking, buying after booking, a bidding process, redeeming miles or certificates, and an operational move by the airline. All five follow their own rules and get confused constantly.

### Why do I get no upgrade despite a high tier?

Because the cabin is sold. An airline only allocates what stays empty after sales, and on busy routes almost nothing stays empty.

### Does the fare count more than the tier?

Often yes. Many programmes sort by booking class first and by tier second, so an expensive fare without status can sit ahead of a cheap fare with status.

### How does a bidding process work?

The airline invites a bid, tests it against an internal floor and decides shortly before departure. A higher bid improves the chance and guarantees nothing.

### Can I upgrade any booking with miles?

No. Mileage upgrades usually require a specific booking class, and the cheapest fares are excluded. The upgrade also depends on award space being released.

### What is an operational upgrade?

A move because the lower cabin is oversold or the aircraft changed. It follows the internal order and is a solution to a capacity problem rather than a reward.

### Does asking nicely at the desk help?

Barely. The list exists in the system before anybody reaches the desk, and staff usually cannot change it. Politeness helps with everything else.

### Does dressing well help?

No. Selection runs on data in the booking system, and nobody sees the passenger before the list is fixed.

### When is an upgrade decided?

It depends on the route: purchases immediately, bids usually one or two days before departure, mileage upgrades on availability, and operational moves only as boarding closes.

### Do I get a refund if the upgrade fails?

A purchased or won upgrade yes, as soon as it is not delivered. A mileage redemption is normally reversed, though not always immediately.

### Does an upgrade count towards status?

Usually the fare purchased counts rather than the cabin flown. Somebody collecting for a tier gains comfort from an upgrade but rarely points.

### Why are upgrades disappearing?

Because airlines increasingly sell empty seats rather than allocate them. Every seat sold is a seat that never reaches the order.
