> The company says the cancellation was approved under its standard policy permitting properties to void bookings in "rare cases where a property identifies a clear rate error." Following Go Public's questions, Booking.com told Mann it would honour her original booking and cover the price difference — allowing her to keep the same four bedroom unit at no additional cost.

Sounds like booking.com made a mistake in applying the wrong policy, and is trying to cover up for it instead of admitting their liability.

twoodfin•51m ago
Right! This is fundamentally the risk of being a broker: You think you will have X available for $Y, sell it, only to discover that X will cost you $Y + Z.

Without that risk you’re not functioning as a broker and shouldn’t be rewarded as one.

jeroenhd•48m ago
They're paying out to cut back on the negative the media attention.

The underlying problem, that hotels are capable of canceling bookings so they can ask for extortionate rates when events nearby take place, still remains.

I'm not sure whose fault this is, really. The person buying the reservation knew this deal was too good to be true, the hotel should've fixed their prices if they want to charge 12k extra for a weekend, and booking should probably kick hotels that do this off their website.

Booking.com is an absolute hell site for various reasons, but I'm sure the same conflict would've happened had the room been booked through the hotel's website.

ArcHound•50m ago
Let's take a look at incentives. Booking.com has an incentive to cancel. The hotel itself has an incentive to cancel. The laws in place don't prevent this, especially when some contractual fine print is involved.

Will this public case result in flood of people away from booking.com? Probably not.

This is just a simple abuse of power, most easily identified by the question: "What are you going to do about it?"

It seems the play is to tell the world. Congrats to this lady for getting her money/booking back.

wslh•24m ago
This is why consumer laws should be really hard and executed very fast, it's the balance to big companies and "perfect" markets.
MichaelZuo•20m ago
Why?

There are plenty of full service travel agencies that offer to book guaranteed price reservations in pretty much any locale in most countries. There are some that even offer extra guarantees like a last minute cancellation by the hotel being refunded at double the cost, to ensure you can get a room elsewhere.

wslh•17m ago
> Why?

Because you live in an attention economy and the probability of using another service is pretty low. We can also develop our own travel agent with LLMs but that's an outlier of the market, and financially negligible. The problem is about power in the economy.

MichaelZuo•7m ago
This doesn’t make sense, how is your preferred range of attention expenditure even relevant?

If a dozen different HN users expressed a dozen different preferred ranges… would there now have to be viable competitors at each possible step?

causal•23m ago
Booking.com is also just a terrible service. Their search is one of the better hotel search tools, but I stopped using them after they "lost" a booking but continued to charge me for it anyway. They denied it existed when I finally reached someone on the phone, despite the very real credit card charge. Only after I got my CC company to chargeback did they send me a cancellation notice.

Incompetence at that level feels like malice.

netsharc•18m ago
Recently they've blocked selecting a hotel's address. I do so to look at the area or public transport options on Google Maps, but I guess too many people look up the hotel website from there and book directly.

imdsm•20m ago
I was concerned about this happening to me, as I booked somewhere really early and prices have since gone 5x. Knowing that booking.com will do this means I'll never now use them, and will tell others the same. Thankfully I used another and got the hotel to confirm it.

netsharc•29m ago
They're terrible, but according to the article the hotel requested the cancellation, and now booking.com has reinstated the booking and apparently paying the difference... seems like they're "the good side" here (or, paying to avoid the bad publicity).

Eugh, I feel dirty defending them.

mikeocool•14m ago
I wonder if the hotel would be less likely to cancel on a direct booking with the same mistake — when their brand would be more directly on the line.
goda90•28m ago
You can find a list of other companies owned by Booking Holdings here: https://en.wikipedia.org/wiki/Booking_Holdings

Priceline, Agoda, Rentalcars.com, Kayak, OpenTable, Rocketmiles, FareHarbor, HotelsCombined, Cheapflights, momondo

no_wizard•26m ago
I constantly get recruiter emails from Agoda. Anyone ever work for them? They want to move me to Thailand which doesn’t make a ton of sense to me, considering I’d be asking for an American level salary regardless
glitchc•17m ago
Since the hotel called her directly to inform her of the pricing error, I don't see that as the booking platform's problem. After all, the hotel is the platform's client. The same thing would have happened if she had booked directly from the hotel.
philipwhiuk•32m ago
Yeah this is common. If they have advance info of an event, they price it up. If you have advance info, they screw you over when they find out.

I had this on Airbnb.

> When Mann booked the accommodations, Formula One organizers hadn't locked in the exact race dates. So she covered her bases — reserving the same four-bedroom unit for two possible weekends in May 2026, both with free cancellation.

> Once the official dates were announced, she cancelled the extra booking, in line with Booking.com rules.

Let's be real here. Booking.com is not the only side stretching the terms of service to the limit to extract maximum value. This speculative booking and cancellation also drives costs up for other consumers who book reservations with honest intent by pulling a bunch of units off the market. It's hard to blame Booking.com for wanting to stick it to her.

kuschku•13m ago
How's she stretching the terms of service?

Free cancellation is an upcharge (often a significant one), which she paid for, and made use of.

It would have been easily possible for booking.com and the hotel to offer rooms at two price points and make the conditions clear ahead of time:

- High price (guaranteed room)

- Low price (based on availability, if F1 is that week you'll get the choice between paying an upcharge, cancellation, or moving the booking to another date)

istultus•11m ago
There's nothing morally wrong with not knowing when you want to take a holiday in advance and acting accordingly to cover your bases. What an interesting sentiment... The only thing wrong with what she did was not to read the fine print and realize that paying for free cancellation meant paying Booking.com to pay on her behalf rather than directly paying the hotel.
fred_is_fred•27m ago
I know it's not a popular opinion but at this point I think anyone who books through a 3rd party basically gets what they deserve. There are no end to horror stories here and with the modern internet there's no reason to use them. In 2002 it was a different story. It may not have prevented this situation but the 3rd party bookers take a cut from the provider and offer you absolutely nothing in return. Just book direct.
the_sleaze_•20m ago
I often get better deals through 3rd parties, and more often than not a better experience.

Booking has stood by me before whereas the little seaside hotel barely has a working phone much less a computer with a person that can operate it.

I have no doubt Booking is fully liable here but for the vast majority of interactions they reduce friction.

mr_mitm•20m ago
I travel a lot to many different places including small villages. I'd like to take advantage of a rewards program, but the places I travel to often don't have one of the large chains. These booking services allow me to get bonus points. I thinks that's a good reason, besides the superior convenience of having a unified interface. I rarely had any issues with them either.

I once mentioned that while checking in at a family owned hotel, and they said they appreciate that the booking service allowed them to compete with larger chains on that front.

seydor•18m ago
People who travel often dont have the resources to deal with so many separate bookings, so they ascribe trust to Booking.com , airbnb etc.

Perhaps if there was some "shopify of accomodation" it would be easier to have a seamless experience. In the meanwhile, the existence of a stable reference point gives the false sense of a trusted travel assistant.

marinmania•13m ago
I travel 3 times a month for the last year and use Booking. I've never had a cancellation.

I take advantage of their platform moreso than they me. I book refundable no-pre pay hotels every time, sometimes having multiple bookings for the same week. It's like a free option on future pricing.

seydor•22m ago

True! Thankfully under Socialism there wouldn't be a Grand Prix in the first place, and the Hotel would be government-run and only house Party members during special events anyway.
hypeatei•3m ago
How would a socialist or communist system decide who gets a hotel room in this scenario? Declaring something as free or public doesn't magically give us infinite resources.
dec0dedab0de•18m ago
I generally search on the aggregate sites, but book directly with the location.

Unfortunately, there are some smaller BnBs that only take booking.com

Although, this article reminds me of people on slickdeals complaining that they got caught trying to buy a type-o.

imdsm•17m ago
Just to add to the dynamic for those too busy to read:

> When Mann booked the accommodations, Formula One organizers hadn't locked in the exact race dates. So she covered her bases — reserving the same four-bedroom unit for two possible weekends in May 2026, both with free cancellation.

> Once the official dates were announced, she cancelled the extra booking, in line with Booking.com rules.

I wonder if this changes our perception of things. If you book two dates and then cancel, are you not also part of the problem?

Perhaps if you didn't go for the free cancellation, then it should be a fair two way lock in, if you commit, we'll commit etc. Still not as bad as when Jason Manford finished a show, turned up at the Village Hotel in Bournemouth, and because he checked in late, they'd given his room to someone else.

guipsp•15m ago
The hotel can just not offer free cancelation
stavros•8m ago
> I wonder if this changes our perception of things. If you book two dates and then cancel, are you not also part of the problem?

If the website said "you can cancel for free", why would I consider myself part of the problem?

If the website said "you can book, but we could cancel your booking for any reason, including because we can rent it to someone else for more money", I wouldn't consider the website as part of the problem either.

As it stands, only one of those two things was prominently mentioned on the website.

cowpig•7m ago
No matter what shady thing a company does you can rest assured there will be a bit of "well, let's think about it from another angle" at the top of the comments section.

The company offers cancellable reservations for a fee. She paid the fee. What are you talking about

dghlsakjg•5m ago
This my exact same reaction.

Every time I have ever seen a cancellable reservation at booking.com I have also noticed that it costs more than the same reservation without cancellation priveleges.

She almost certainly paid for the flexibility.

globular-toast•5m ago
A deal is a deal. If the hotel doesn't like it then don't offer that deal to the next customers.
Cerium•5m ago
Not only can the hotel select their own policies, but the cancellation is 6 months early. Surely the room will not go empty in that time.
blitzar•3m ago
> I wonder if this changes our perception of things.

It does not.

the__alchemist•2m ago
I had the same thought when reading that line. I think we can treat it independently from the article's main point. So, yes - this is a common consumer tactic for reservations of all sorts. (It is a thorn in the side of restaurants, and why you get emails asking you to Confirm appointments) And it disadvantages both the business, and other consumers.

But... I don't think it impacts the main point of the article.

meindnoch•11m ago
"When Mann booked the accommodations, Formula One organizers hadn't locked in the exact race dates. So she covered her bases — reserving the same four-bedroom unit for two possible weekends in May 2026, both with free cancellation.

Once the official dates were announced, she cancelled the extra booking, in line with Booking.com rules."

And then Booking.com cancelled her booking, in line with Booking.com rules. Shit goes both ways.

stavros•6m ago
Funny, I've never noticed "we can cancel your booking for absolutely any reason we want" under the "free cancellation" text. It's almost as if one is shown really prominently, and the other hidden under a mountain of text.

But I know nobody would consider the two equivalent, so I must be mistaken. Right?

injidup•11m ago
It's simple. Booking.com will fuck you over and have all sorts of fine print to cover themselves. However I can simply recommend if they do something like cancel a confirmed booking don't bother contacting customer support. Simply get on Facebook and start swearing and causing a huge fuss till they sort it out. They will tell you 100 times that they are very sorry and they would love to help but they just can't and they feel horrible about it all but "the policy" forbids them doing anything that could smell like genuine customer service. Simply raise the temperature of agitation just as this customer did and eventually booking.com will buckle.

I had exactly the same case. I had a non cancellable room booked for an event and a week or two before the event it was cancelled and booking tried to claim they were not an agent, they were not part of the contract, that they cared very deeply. Customer support in English cost 1€ per minute and they kept putting me on hold. Eventually I just went to Facebook and asked GPT to start incrementally generating more and more offensive posts direct at their social media account. It's much cheaper than their customer support line and it actually reaches someone who can do something.

renewiltord•11m ago
I don’t know why everyone is saying you shouldn’t use booking.com. The story is that the person booked two weekends and canceled one. The hotel canceled the other and upcharged. Then booking.com paid the $13k difference? I don’t know. This makes it more likely I’ll use booking.com. If they booked directly with the hotel they would just lose the room.

With booking.com they’re big enough that making a fuss in the media gets you a $17k room for $4k. I’m taking that deal every single time haha.

hudo•10m ago
My booking.com latest experience: booked big appartment for 4 people. Arrived to destination (Bristol, UK), and apartment already had guests inside. Tried contacting landlord, no reply. Called booking com, they offered acommodation 30km from the city centre, and its already 11pm, no way to get there. Had to pay our own hotels, and we never got money paid to booking. One neighbor of that apartment said they often double book! Seems booking com doesn't care.
oniony•7m ago
I recently had a hotel try to scam me through the official Booking.com messages. Knew my phone number (they also WhatsApp'd me), me booking dates and email address (got more attempts via email). Spoke at length with Booking.com and, despite using them virtually weekly for fifteen years, they did not give a crap and then stopped responding to my emails. I will not use them again, just like I do not use Travelodge any more since they repeatedly double-booked my rooms. I feel like, eventually, I'm going to run out of brokers to use. Perhaps I just need to book direct with a handful of hotels.
stickfigure•6m ago
I have found that it's always better to book directly with hotels. The price is the same or better, but more importantly, it's waaaay easier to make changes or cancellations without the middleman.

And rentalcars.com is a flat-out scam. I had to dispute CC charges with them when I showed up on scene, there were no cars, and rentalcars wouldn't refund it. Always book with the rental company directly.

potato3732842•5m ago
This is how the hotel industry works. This isn't just a booking or expedia thing. If the hotel knows they're gonna sell the house they'll shit-can "cheap" reservations that were made a long time ago. Even if Booking.com or whatever middleman online travel agency you're using doesn't facilitate this, the hotel itself will do it.

Every time there's a big event somewhere a bunch of people who booked before the event was publicized get bit by this.

drra•3m ago
Travel industry especially OTA behemoths like booking or expedia live by exploiting all possible quirks of the systems. For example they could snap super cheap airline promo fares but manipulate it to keep it in an open state for months similarly to how agents wait till the payment clears. Would be than sold with massive profit or abandoned close to flight date without any penalties. Apparently they rotted enough for start blatantly cancelling hotel bookings.
