The short version

  • Each has a real cost: Booking.com the commission Booking.com charges properties, typically 15 to 25 percent of the booking value, is invisible to the traveller and often built into the displayed room rate, so the identical room booked directly with the hotel can sometimes be cheaper.; Kayak it is owned by Booking Holdings, the same parent as Booking.com and Priceline, so its comparison results are not fully independent of its own group's commercial interests.
  • They diverge on capability: Booking.com covers Accommodation search and booking, Kayak covers Flight, hotel and car comparison.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Booking.com

  • The commission Booking.com charges properties, typically 15 to 25 percent of the booking value, is invisible to the traveller and often built into the displayed room rate, so the identical room booked directly with the hotel can sometimes be cheaper.
  • Cancellation policies vary entirely by the specific rate a property has set, not a platform-wide standard, so travellers must check each listing individually rather than assume consistent flexibility.
  • Review authenticity depends on Booking.coms own verification process for guests who booked and stayed, which travellers cannot independently audit beyond trusting the platforms stated methodology.
  • Customer service for booking disputes often requires involving both Booking.com and the property directly, since the platform is a marketplace intermediary rather than the accommodation provider itself.
  • Some properties, aware of the commission cost, offer better rates or perks to guests who book directly by phone or through the hotels own website instead, undermining the price transparency travellers might assume the platform provides.

Kayak

  • It is owned by Booking Holdings, the same parent as Booking.com and Priceline, so its comparison results are not fully independent of its own group's commercial interests.
  • Some airlines opt out of listing on metasearch sites entirely, so Kayak's results are not a complete view of every available fare in the market.
  • Revenue comes from referral commissions, and prominence in results can be influenced by which suppliers pay Kayak more, not purely by lowest price.
  • The actual booking typically completes on a third party site, so problems with a booking, cancellation or refund are handled by that site's customer service, not Kayak's.
  • Displayed prices can change or fail to match by the time a user reaches the booking site, since Kayak is not always querying live inventory in real time for every listed fare.

Answered from the vendors’ own pages

Booking.com: Is Booking.com free to use?

Yes, for travellers there is no subscription or booking fee charged directly. The platform earns money through commission charged to the properties listed, typically 15 to 25 percent of booking value.

Kayak: Does Kayak charge a booking fee?

No, Kayak itself is free to use; it earns referral commissions from the airlines, hotels and sites it sends bookings to.

Booking.com: Why might a hotel be cheaper if I book directly?

Because the hotel pays commission, typically 15 to 25 percent, on bookings made through Booking.com, some hotels price rooms to absorb that cost or offer a lower direct rate since they keep the full amount without paying the platform a cut.

Kayak: Do I book directly through Kayak?

Usually the booking completes on the airline, hotel or travel site's own platform after Kayak hands off the click, though some direct booking options exist for select content.

Booking.com: Does Booking.com own the properties it lists?

No, it is a marketplace connecting travellers with independently owned and operated properties; Booking.com does not own or operate the hotels and accommodations listed.

Kayak: Is Kayak owned by an airline or hotel chain?

No, it is owned by Booking Holdings, which also owns Booking.com, Priceline and Agoda.
