The thing I find interesting about a lot of things like this is that they feel like a holdover of half the era where negotiating prices was normal: today, for most people in the US, most shopping is just a matter of going somewhere and paying a set price and you don’t argue with the seller to get a better one. B2B transactions still usually involve a negotiation, I think, but it’s basically gone for consumers.

With something like airfares, the business is still doing its half of negotiations: collecting bits of data about the buyer to determine a price; but, crucially, there’s no real way for the buyer to “talk back” and so the process seems arbitrary.
