The short version

  • Each has a real cost: Expedia package deal pricing is not transparent, since Expedia negotiates bundled rates with airlines and hotels and adds its own margin, making it difficult for a traveller to verify whether a bundle is actually cheaper than booking the same components separately.; 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: Expedia covers Flight and hotel packages, 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.

Expedia

  • Package deal pricing is not transparent, since Expedia negotiates bundled rates with airlines and hotels and adds its own margin, making it difficult for a traveller to verify whether a bundle is actually cheaper than booking the same components separately.
  • Hotel commission, typically in a 15 to 25 percent range similar to other online travel agencies, is built invisibly into displayed rates, so the same room can sometimes be found cheaper booking directly with the hotel.
  • Cancellation and change policies for package bookings can be more restrictive than booking each component separately, since changing one part of a bundle can affect the priced discount on the rest.
  • Customer service for package booking issues can require coordinating between Expedia and multiple underlying suppliers, airline and hotel, which adds complexity compared with a single-component booking.
  • One Key reward point value and redemption rules have changed as Expedia Group consolidated its previously separate loyalty programmes, so points earned under older programme structures required migration and are not always a like-for-like conversion.

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

Expedia: Is Expedia free to use?

Yes, for travellers there is no subscription or booking fee charged directly. Expedia earns money through hotel commission and margin built into package deals.

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.

Expedia: Is a flight and hotel package actually cheaper than booking separately?

Sometimes, but not reliably, since package pricing includes a margin on top of negotiated bundled rates; a traveller who wants to verify needs to price both approaches independently.

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.

Expedia: What is One Key?

A loyalty rewards programme shared across Expedia, Hotels.com and Vrbo, allowing points earned on one brand to be used across the others.

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.
