Sign UpGet the New Statesman\'s Morning Call email. Sign-up Are algorithms trying to steal our children? That’s the question at the heart of the latest airline ticket pricing scandal. Are budget airlines trying to squeeze more money out of families by deliberately allocating them seats in separate parts of the plane, then forcing them to pay a fee so that children can be seated next to their responsible adult? The airlines claim that when the fee isn’t paid, seats are simply randomly allocated. When the BBC’s Watchdog programme did some trials, a statistician claimed the result – in which every single person who booked was assigned an undesirable middle seat – was less likely than a National Lottery win. As far as price gouging goes, airlines certainly have the means, motive, and opportunity. Plane ticket booking systems are a science developed over decades, and before they could rely on computers there were all sorts of wild and wonderful systems and contraptions: simple paper ledgers were replaced with index cards, which became blackboards, which became vast systems of boards of coloured chips. There was even a mechanical device that represented flight capacity, with tubes representing flights, filled with tiny plastic balls representing the seats. When a seat was booked on a fight, a button was pressed and a ball would pop out of the corresponding tube. Algorithmic price adjustments have become a key part of this model, enabled by the vast amount of data that an airline booking system has to track just to function. Airlines have a huge incentive to maximise the number of people they can book on to any given flight and the amount of money they can extract from any given individual, too. While a passenger may be presented with a simple choice between economy and business, an airline has a far more sophisticated model based on how many tickets it can sell at any given price – which is why prices can fluctuate so wildly on online booking sites. The person in the seat next to you may to all intents and purposes have the same flying experience, but as far as the airline is concerned will have bought a completely different ‘product’. As well as how far ahead a ticket is purchased, it’ll also factor in the likelihood that a ticket is being bought for business or pleasure: if it believes a ticket bought last minute midweek is most likely to be bought by someone on a work trip, it’ll jack up the prices. This has inevitably led to an attitude of deep suspicion towards these companies. The jury is out on whether the widely believed idea that companies use browser cookies to hike the price on a second visit is actually something that really happens: one study found that, in 59 per cent of cases, checking the price again anonymously actually resulted in a higher price than if not trying to mask the user’s identity. In fact, it could just be a consequence of how volatile every other part of the pricing system is: but everyone still believes it anyway. Whether or not this latest controversy is deliberate attempt to gouge people or the result of an algorithm that’s not been properly thought through, in an industry that’s grown up around gaming the system it wouldn’t be particularly shocking if someone had tried to do something like this to coin in a few more booking fees. On the face of it doesn’t seem like all that a great strategy: aside from the existing PR backlash from anxious families, it doesn’t take much imagination to ponder the, at best, tiresome, scenarios that might result from randomly seating unaccompanied five-year-olds on a packed flight. The UK Civil Aviation Authority policy on this is that children should never be seated more than one seat away from a responsible adult: some of the budget airlines have simply made paying a fee a requirement for families. Presumably the algorithms will report the cost-benefit analysis of this grimy behaviour and adjust the fees accordingly. There might be other, more profitable avenues anyway. Perhaps you could accept a cash payment from unruly teenagers to be moved away from the square parents they’re sick of after a two week holiday? Or charge people travelling on business a small fee to be surreptitiously parted from a particularly flatulent colleague? And what do the algorithms have to say about sedating passengers and stacking them up in coffins? › We still do not know the true scale of the Windrush Generation scandal Subscribe For more great writing from our award-winning journalists subscribe for just £1 per month!
