If you've a commodity that can only take limited customers, say concert tickets or flights on planes, it's not unreasonable to try to get mucho money from people who want to go. And then to lower the prices later, if you've not been able to sell at top dollar. And then, in the case of airlines, to bilk the passenger who absolutely needs to fly somewhere tomorrow. This is basically rationing. The people who want it more, pay more. The people who are willing to go to any gig, or fly at any time, can wait until the last minute and then see what wasn't as much in demand and take that for cheap a few days before.

Or.... and hear me out here... you can work out what your cost of product/service is, decide what your margin should be, and then sell your products/tickets/services at that price. Why shouldn't everyone pay the same to get on the same flight or into the same gig? These companies know what their price points are. They know that an Oasis gig will command higher prices than some little band on their debut tour. When the flight is full, it's full. There's no operational reason to ramp the prices so the last 3 seats cost 4x more than the first 3. Or so that they cost more on a Saturday evening when people are watching TV and see an advert and pull out their laptop to book a holiday.
Of course even in the analogue era, there was a level of demand pricing - a hotel would have it's rate card (probably with high/low season pricing), and then they'd have the tariff board behind the counter for anyone who walked in and asked for a room that night. But again, at least it's transparent, rather than looking the person up and down and making up a number on the spot.
However, I wouldn't allow this for trains, or other public transport, in the UK - as we want to reduce car use so shouldn't penalise people for not knowing where they're going in advance.
It's unfortunate that we absolutely do this as a form of demand management, and yeah, it should be banned (and unnecessary). The problem with trains vs planes of course is planes have a booked seat - trains can (in principle) run to standing-room-only. They don't run out of tickets as such (at least not the way we run them) - so pricing encourages people onto quieter services. BUT this is a product of us not investing in our railways for 40 years and running them very inefficiently and at low density. A great shame HS2 was scaled back as this would quadruple the number of local services we can operate once the ICE trains are segregated onto their own line.
I would note that this could be applied to plane tickets as well. I know someone whose mother (in Spain) was taken gravely ill and just had to bite the bullet and get the next flight out, hang the cost. They were in a privileged position that they could, but others aren't. Particularly in the UK, with the issue that Eurostar is not very well run, doesn't run as many services as it should, and charges the hell out of the ones it does. Insane that it's generally more expensive than the equivalent flight (although not by as much as we might think including airport transfers/parking/etc). Aviation is not always a luxury/holiday commodity the way concert tickets are. Of course we need to get continental rail services sorted, but aviation is actually a form of public transport - albeit one that needs to be deprioritised versus rail.
Universal Credit tickets available for £1 -- Manchester United used to have a scheme where you could queue up on a Tuesday morning to buy discounted tickets for Old Trafford matches, to guarantee that local supporters could get in, when prices suddenly jumped up to £70. Bet they don't do it now. Most football clubs limit scarce Cup and European ticket sales to people who've got season tickets or have bought a certain number of tickets in the last season, so the "real fans" get first dibs on the limited resource.
These are just discounts though. They're not the sort of airline dynamic pricing where they bump prices based on whether you've looked those particular flights or destinations before. Moreover, they're transparently declared ahead of time. If you're on UC, you get cheap entry. If you want scarce tickets that badly, join the supporters club. This isn't a perfect system of course because you're discriminating against low-income fans who perhaps can't afford to attend many matches, but would get up at 3am to queue for tickets (when other - better heeled - fans wouldn't, but they can just buy membership or a bunch of minor match tickets to qualify for the scarce matches).
Look at Walker's crisps. -- But I don't think we should legislate for it. How do you define quality?
We've drifted well away from demand pricing here. This is just cost of living, along with supermarket's "consent or pay" shenanigans. Upfront pricing like that is for the markets to decide. If Apple or Walkers are too expensive then people won't buy them. Vertu phones are insane money for what they are, but a handful of more-money-than-sense people buy them. That's fine. What should be legislated against is the idea that Apple charge more because your tracking cookies/advertising ID shows that you've looked at certain other brands and they've inferred they can bilk you for more. Apple are actually fine. That's an example of that I want - they set a price, and that's what you pay and I don't have to waste my life trawling through camelcamel working out that if I logon at 8.33am on the second Monday of the month using Safari 26.1 I can get a discount for <reasons>.
Sure, Apple drop the price on old models, and have their refurb programme, but their prices don't wander up and down algorithmically the way airline prices do.
Of course, if we banned RTB advertising and moved back to contextual ads, then most of the tracking and datasets used to drive dynamic pricing simply wouldn't exist, which is possibly a neater "two-birds-with-one-stone" way to wind ourselves back to some sort of vaguely transparent pricing policies. So there's that.
