For the most part, free flight upgrades in Australia are the stuff of urban legends. You’ve probably heard whispers of it wafting through airport terminals, but never encountered one yourself.

Yet, free upgrades to premium cabins do exist. It’s just that airlines understandably don’t want to give them out without a great reason, for fear that it devalues their premium cabin products for actual paying customers.

Singapore Airlines is notoriously strict with free upgrades.

With that in mind, we’ll explain how exactly these free upgrades usually work, and why the tips you’ve read in the mainstream media, such as dressing up for the flight, probably won’t get you anywhere on their own.

Also, it’s best to temper your expectations now. Free upgrades are extremely rare, so the best approach is to pay for an upgrade with cash or points or book into the higher cabin class directly.

Why would an airline want to give out a free upgrade?

1. Discretionary or loyalty upgrades

In the US, loyal frequent flyers can automatically be considered for complimentary upgrades on short domestic flights as a published benefit – particularly with the big names American Airlines, Delta and United.

That’s not the case in most other countries. Here, you should expect to use your frequent flyer points or bid some cash for a shot at the upgrade, even with domestic trunk routes such as Sydney-Melbourne.

Having said that, Qantas has occasionally surprised and delighted Platinum frequent flyers (and higher) with complimentary upgrades on quieter flights for loyalty, rather than operational reasons. But these treats are few and far between.

Even on shorter domestic flights, you’re expected to fork out for your upgrades.

International airline policies on complimentary upgrades can be very different too, ranging from lenient to a strict ‘computer-says-no’.

For example, Qatar Airways has been known to treat its high-flying Platinum members to an occasional First Class upgrade from Business Class on the Airbus A380. But Singapore Airlines is said to be notoriously strict on discretionary free upgrades… unless you’re a Solitaire PPS Club member flying close to your birthday *wink*.

2. Operationally-necessary upgrades

If you do get tapped for a cabin change before boarding, or even onboard, chances are you’ve been given an operational upgrade or op-up for short. This is industry-speak for free upgrades that are operationally needed.

For example, the lower cabin class might be overbooked, or perhaps a seat is faulty and someone needs to be moved up. In extreme cases, an aircraft change could result in fewer Economy Class seats being available while Business Class has some spare seats available.

Doing so frees up space in the lower cabin class to accommodate the overbooked passengers. You get to enjoy the benefits of an upgraded cabin class. It’s generally a win-win situation for all.

Sometimes, op-ups will happen across several cabins. For example, say Economy Class is overbooked, but Premium Economy is also full. In this case, someone from Premium might be bumped to Business Class, freeing up space for someone to be upgraded from Economy to Premium.

As a datapoint: out of the hundreds of flights I’ve taken, I’ve received an unexpected op-up just once. As a Platinum member, I was about to fly Qantas from Rome to Perth in Economy. Before take-off, another passenger and I were bumped to Premium Economy. The reason? To make way for a family who wanted to sit together.

How are free upgrades allocated?

Of course, most airlines don’t talk about the processes behind deciding op-ups. But based on years of collective experience and insights, the following factors are invariably present in most scenarios.

1. Your frequent flyer status is key

Most people in the industry will agree that your frequent flyer status with a particular airline is one of the most critical factors. When faced with picking a Gold or Platinum member against a passenger with no status, you can expect that the former will be chosen.

But even if you don’t have an elite airline status card, holding a base-level membership is better than nothing. If it’s a choice between a Bronze member and a non-member, then once again we’d expect the former to win.

In some cases, your partner airline elite status may be considered, such as Qantas status on Emirates flights or Velocity status on Qatar Airways flights.

Unsurprisingly, Platinum members are higher up on the list when airlines need to upgrade someone.

2. Your ‘passenger value’ is important too

Many airlines maintain a secret metric that measures the ‘worth’ of each passenger to the airline. In Qantas parlance, this is called ‘PCV’, or perceived customer value.

Your PCV increases if you book more expensive fares, fly more often, or have a special business/SME rate. These values could be used to decide which Platinum member gets the upgrade over another, for example.

On the other side of the spectrum, if you’re a VIP with an invite-only membership, such as Qantas Chairman’s Lounge or Emirates iO, then you may find that complimentary upgrades happen more frequently, even when a flight is not overbooked.

3. It’s more likely to happen on leisure routes

You may have a better chance of getting a free upgrade if you’re travelling on a flight that’s often full in Economy, such as on a leisure route. If the lower cabin is oversold, then some op-ups may need to happen.

4. Travelling on your own can help

Solo travellers will usually get first consideration for an upgrade. That’s simply because it’s easier to juggle around one person rather than two or more, which then comes with seating arrangements and so on.

Solo business travellers with elite status are often in a good position to be upgraded.

5. It also doesn’t hurt to ask

This is where the ‘human element’ comes into play. Consider asking if any discounted upgrades are available and see where that leads you. Remember, you’ll probably not get an upgrade this way – particularly if you don’t have the frequent flyer status to back you up. But there’s nothing wrong with giving it a try.

As always, treat staff respectfully and don’t put them in an uncomfortable position by arguing for a free upgrade.

Summing up

Chasing after a free upgrade? In most cases, it comes down to sheer luck, and it might strike when you least expect it. Outside of the US, airlines don’t make a habit of dishing out upgrades for goodwill. There’s usually an overbooking or other similar operational need behind it.

But if all the stars align, you might just hear that magic beep and red light at the gate, before your old boarding pass is removed and you’re presented a new one for the next cabin class up.
