Delta has a long-term strategy to boost its profitability by moving away from set fares and toward individualized pricing using AI. The pilot program, which uses AI for 3% of fares, has so far been “amazingly favorable,” the airline said. Privacy advocates fear this will lead to price-gouging, with one consumer advocate comparing the tactic to “hacking our brains.”
The higher a percentage of your income is the price of something, the more reason there is to allocate time to find the best price - if something costs you an amount which you earn in 5 minutes, it’s not really worth it to spend time looking for the better price, if it costs an amount which you earn in 2 months, it’s definitelly worth to spend at least several hours looking around.
Granted, as you say, many don’t have the time to do this (though often the Maths for literally taking time of work to do it, do add up), and in my experience most people don’t really make the mental connection between an amount they’re considering spending and how long do they have to work to earn it hence don’t really look around enough when it’s financially logical to do it.
That said, for the reason I gave above, the rich don’t really care about things that “just” cost a couple thousand of dollars, which is why they casually just rent a private jet for a trip - there’s a whole industry for that - or even own one and employ a pilot for it fulltime.
