> I would be unambiguously outraged only if they were gouging everyone and making fat stacks.

No, the thing they're doing is still awful.

The basic problem is that they do actually have competitors and are offering a product which is basically fungible, so their margins are inherently going to suck, even if they do every slimy thing, because then their competitors will just do the same thing and they're back to having thin margins only now they've made everything more deceptive/inconvenient/confusing.

The ideal thing in a market like that is to have an efficient way for customers to cut through the BS and find the best price for a ticket that isn't screwing them in covert ways, because then the deceptive tactics don't work, which takes away the incentive to do them. They'll still have thin margins, only with less deception.

But an individual airline can't unilaterally allow that if their competitors have a way to block it or they'd be at a competitive disadvantage, so they're going to try to stop that from happening. It's in no one's interest -- not even theirs -- to let them. They just need you to not let their competitors get away with it either.

> Maybe this was a failure of antitrust.

It's a failure of customer protections laws. The same service legally should cost each customer the same. Sophisticated pricing schemes should be just plainly illegal.

You can't put an item in the store on the shelf and charge every customer what you like. You have to put up a price and adhere to that price regardless of who wants to buy. Anything else is illegal. Or at least should be.

It should be but unfortunately I don't think it is. The main reason store prices are the same for everyone is because it wasn't practical to individualize them without making it clear to purchasers that they are getting screwed. Still, store membership programs / value cards are one way this is being done in a limited way. And some stores are already switching to digital price labels which can be updated instantly so this is going to get a whole lot worse.

In Poland its a law for physical stores. If you put out a product for sale you must label it with a price. And the product and the price constitute a sell offer. Buyer can accept your offer and then you have to give him the product for exactly that amount of money. Anything else is illegal. If you made a mistake in the price, that's the cost of your mistake.

Of course you can!

I definitely have increased the price of consulting for "annoying" customers doing stuff I don't want to do. Many moons ago, I was doing some contract training for a small airline here in town. I liked teaching but I didn't really want to do the training they wanted me to do - it was a pain in the ass, it took a week, and didn't really pay enough to justify the opportunity cost.

So I kept raising my price, and eventually, they stopped asking me to do the training. It was great because I didn't have to do the thing I didn't want to do anymore, and I made more money. You are allowed to charge different people different amounts of money - some people are just a pain in the butt and charging more pays for the lack of sanity.

reply
But that's just charging different amounts for different services. Not at all the same as the typical end user price discrimination which is all about charging whatever you can get away with with that particular cusomer.
reply
I agree with the principle but where I think price discrimination goes too far is, for example, Uber charging people more by age or statistically imputed income. Or PlayStation charging more for a game by the time of day.
reply
Notice the difference. One is charging people more because they're actually costing you something by imposing an inconvenience, the other is charging people more because you've X-rayed their wallet and set the price to be the amount that cleans them out.

Notice also the thing the customers should be doing in response to the second one: Sharing the prices they're shown for everything with the other customers so they can arbitrage by having the person offered the lowest price be the one to order it.

reply
So is the idea that laws should allow price gouging only for certain reasons that they must be able to justify?

That would get gamed immediately and we'd be in the same spot. Allow price differences for problem customers that require more attention and airlines will say that why they change prices basedcon certain factors.

reply
The idea is that if you have a handful of customers and you offer bespoke service to each you can have custom pricing. If you offer standardized service to many customers, you can't.

Ah, but this is worst in industries where resale is not possible. For example, flights, digital games, and rideshare. Of course one has the option to just not fly, buy games, or use Uber, but this limits a lot of convenience and function in a modern society. This is why I think targeted regulation is not such a bad thing - provided, as you explain, that the reason for the price discrimination is not because the customer actually costs the business more.

reply
It's not practical to have customers coordinating purchases in that manner. What should happen is the customers report to a regulatory agency "this seller is engaging in illegal price discrimination" and that agency brings the hammer down.
reply
But you don't have a way to figure out what your competitors are charging and have automated systems find the maximum you can extract without losing the customer
reply
Its a failure of customers, we don't have to pay them our money and fly on their planes.

If we really care about prices changing per passenger, quality of services, terms and conditions, etc them just don't fly with the airlines that have those practices you disagree with. If that's every airline, well you don't have to fly at all.

reply
I agree in principle but airfare pricing must be more complicated and harder to get right than normal retail. Seems crtainly worth trying to get this right tho
reply
So then, haggling should be illegal and banned or is this idea of "one price for everyone" only to be applied to airline tickets?

Negotiating a price is as old as humans. "That merchant over there is charging 10% less. Can you beat that?", "I want to buy 10 of these, can you give me a bulk discount?"

I have friends that haggle at local stores. One goes does the "Store X is cheaper thing". Another does "My parents live in Oregon where they're is no sales tax, can you lower your price to cover the difference? Otherwise I'll just have them bring it down from Oregon", etc....

reply
How do you haggle with algorithm that is being fed on aggregated data of who you are, how much do you make and what you did yesterday?

It is nowhere close to example you gave.

reply
Exactly. Haggling makes sense when the two parties hav similar levels of information and agency. For entirely one sided transactions where one party has all the power such arbitrage only benefits the powerful party and it is very reasonable for us to come together and decide to make that illegal.
reply
That's not true.

There are many conditions under which price variation allows the seller to maximize the overall amount of services/products that it sells to the largest number of people, all of whom feel like they're getting a good deal.

Should a loaf of bread cost the same thing in Malaysia as it does in the US? No. And if you required it to be such, then people in Malaysia simply wouldn't have bread, and people in the US would likely have higher prices because cutting off less-wealthy markets would reduce the economies of scale that drive overall prices.

reply
This reminds me that flat pricing is a relatively new invention

>> For most of human history, you had to haggle over prices before you could buy something. The Quakers were among the first people to commit to fixed prices — and they did it because it was good morals. Turned out, it was also good business. This is the strange story of the long journey of that little piece of paper.[0]

Seems maybe this is just getting back to haggling, except where the seller has an unfair advantage, and we are trying to eke back a somewhat fair playing field using AI.

It could end up that (maybe wishful thinking), if enough people do it, United Airlines banning AI booking agents may lose them enough business they will need to cut prices or invite in AI agents.

Market segmentation is widely practiced. I believe your objection is not to the overall practice but rather certain aspects of it.

My local grocery store has a senior discount on Tuesday mornings.

Many places have student discounts.

Some places offer a discount if you buy in bulk.

I used to be a book store club member, which would give me a discount on prices. A local history club has monthly public talks, with discounted prices for members. And of course most grocery stores have that sort of scheme.

My father worked for a company which offered family discounts to its employees.

You'll find little support for making all of those illegal.

Of course some of these schemes are illegal in some areas, such as a bar offering discounted drinks for women, but those fall under civil rights law, not customer protection.

I tried to come up with a solid way to prohibit the market segmentation practices you don't like, but it's such a slippery concept that I failed.

Like, consider how some regions require bars to close by, say, midnight, but members-only clubs are allowed to be open after hours. These clubs respond by making membership trivial -- show up at the door, apply for membership, and you are in.

"Do you want to apply for the student club? Membership is free, with student id, and then you can pay the student club fee rather than the public fee." Repeat with "retired club, with proof of age" and "frequent buyer club', etc.

reply
The main difference between your examples and what prompted this discussion is transparency. The student/senior discounts aren't actively hidden from other customers.

And bulk discounts aren't market segmentation, but a way for the store to pass on reduced costs due to lower overheads to the customer. Again, they are also usually clearly disclosed because incentives are aligned.

reply
I mentioned grocery store cards. I'm pretty sure you know that while they show club prices on the shelf, many actively hide additional discounts by offering personalized discounts, right?

I don't every remember seeing places which are transparent about the discounts they offer staff and family off staff. At the very least, I've never seen signs listing those discounts.

Okay, it's not market segmentation. My comment was in response to what scott79 wrote: 'You have to put up a price and adhere to that price regardless of who wants to buy.'

That means that if I didn't list a bulk price and someone comes in and asks what the discount is for a bulk order, then, what, I need to refuse them?

Or can I can scribble the price on the tag right then, for the sale, and erase it immediately afterward?

I'm simply not able to figure out what the guidelines should be. I'm also not sure that "transparent" is that useful of a term, given how easy it is to put clauses in terms&services which people affirm without reading.

Or from HHGTTG: “But the plans were on display…” ... “It was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard.”
