The great airline baggage shakedown: why your carry-on bag is now their most profitable piece of real estate

I want to tell you about something I witnessed recently at Gold Coast Airport that made me put my boarding pass in my pocket and stand very still, trying not to attract attention.

I was in the queue to board a Jetstar flight to Adelaide – which is already, let’s be honest, not the most spiritually elevating experience available to a person on a Thursday morning – when the gate staff began pulling people out of the line. Not randomly. Purposefully. With scales.

Hand luggage was being weighed. Those whose bags exceeded Jetstar’s 7-kilogram carry-on limit were directed to a lady with a cash card machine, where they paid an excess fee and then – and this is the part I want you to sit with for a moment – they put their bags back in the overhead locker. The same bag. On the same flight. In the same aircraft.

The bag did not go into the hold. It did not get checked. It went into the overhead locker exactly where the passenger had always planned to put it. The only thing that changed was that the airline now had more money.

I stood there doing that thing where you look around to see if anyone else is as bemused as you are, and several people were making exactly the same expression, which is the face of someone watching a confidence trick performed in broad daylight and having to admire its audacity even as they resent it.

Because here is the thing. If there were a genuine safety concern about the weight in the overhead locker, the bag would go into the hold. That it stays on board, in the cabin, in the overhead locker, with the only change being a transaction at a desk – tells you everything you need to know. This is not safety management. This is revenue collection with a measuring tape.

The Australian picture

As Australia’s flag carrier, Qantas allows economy passengers one main cabin bag of up to 7kg. From 9 June 2026, the cost of additional checked baggage on Australian domestic and international flights increased.

Jetstar, as a budget carrier, has stricter carry-on limits than full-service carriers. On all domestic and international Jetstar flights from January 2026, the available airport baggage allowance is 20kg, with excess charged at $15 per additional kilogram on domestic flights and $25 per kilogram on international flights.

Virgin Australia charges for checked baggage on its Economy Lite fare from $35 per sector when booking online, with higher charges at the airport. Extra bags beyond the included allowance cost from $45 per sector.

The pattern is consistent across all three carriers: the price is always lower if you pay in advance online, always higher if you present at the airport with a problem, and always higher still if you present at the gate with a problem. The pricing architecture is specifically designed to punish the disorganised and reward the obsessively prepared. Which is to say, it rewards the airlines.

The broader Australian context is worth understanding. The Competition and Consumer Commission has periodically examined ancillary fees in the aviation sector, but the fundamental model – advertise a low headline fare, then charge separately for everything that makes flying tolerable – is entirely legal and increasingly standard.

The global picture

Zoom out and the numbers become genuinely staggering. US airlines brought in more than $7.4 billion in passenger baggage fees in 2025, a 162 per cent increase over five years. That is not a typo. One hundred and sixty-two per cent in five years. In the span of two weeks in April 2026, every major US airline raised its checked bag fees, all citing rising jet fuel prices in the wake of the war in the Middle East. When one carrier moves to raise prices, the rest quickly follow.

United raised its fee to $50 for the first checked bag and $60 for the second on flights within the US, Mexico, Canada and Latin America. American Airlines charges $50 for the first checked bag, with a $5 discount for online purchase at least two hours before departure. Delta charges $45 for the first checked bag for main cabin customers.

Globally, ancillary revenue – the industry term for fees collected on top of the base fare, including baggage, seat selection, food and wifi – was projected at $148.4 billion for 2024 across 61 airlines surveyed by the IdeaWorksCompany. To put that number in context, $148 billion is roughly the GDP of Hungary. The entire GDP of Hungary, generated by airlines charging people to put their suitcases in the hold and sit somewhere specific on the plane.

The highest-performing carriers concentrate on two categories: baggage fees and dynamic seat selection pricing. Overhead carry-on bag fees generate approximately $20 per passenger at the top performers.

Twenty dollars per passenger. For the overhead locker. Which was always free.

How we got here

The unbundling of the airfare began in earnest in 2008, when American Airlines introduced a $25 fee for the first checked bag – a decision the rest of the industry had adopted within months. The logic was transparent enough: as low-cost carriers competed aggressively on headline fares, legacy carriers needed ways to maintain revenue without raising the advertised price. Fees were the answer. Ancillary revenue is expected to be the single most significant contributor to nominal sales growth in 2025, according to IATA’s own economic outlook.

The airlines do not pretend otherwise. They call it “unbundling” or “a la carte pricing” — the idea being that passengers only pay for what they use. In practice, what it means is that the advertised fare now represents an increasingly small fraction of what the trip will actually cost you by the time you have paid to check a bag, selected a seat that is not in the middle of the back row next to the toilet, and bought something to eat on a flight longer than two hours.

What you can actually do about it

There are, in fairness, legitimate ways to reduce what you pay. Virgin Australia’s Economy Choice fare includes 23kg of checked baggage, making the headline fare comparison with Jetstar more complex than it appears. Qantas Frequent Flyer status from Gold tier upwards typically includes checked baggage allowances. Many airline credit cards – the Qantas Premier, the Velocity credit cards – include checked baggage benefits that can offset their annual fee for regular flyers.

The most effective strategy, unglamorous as it is, remains the same one it has always been: pack less. A 7kg carry-on bag, if you are disciplined about it, genuinely is sufficient for a week in most climates. The travellers being pulled out of the Jetstar boarding queue at Gold Coast with overstuffed cabin bags had, in a sense, made their own problem. But the system that turns every kilogram over the limit into a revenue opportunity – while keeping the bag on the same aircraft regardless – is one designed to extract money from inconvenience. That much, at least, is worth saying plainly.

The bag stayed in the overhead locker. It was always going in the overhead locker. The only question was how much it would cost.
