Honest review

Is HotelsCombined legit?
Yes. A KAYAK site, at KAYAK's prices.

HotelsCombined is a hotel search site that compares prices from other travel sites. Booking Holdings, the company behind Booking.com and KAYAK, completed its purchase in December 2018 and said it would report into KAYAK; its terms name HotelsCombined Pty Ltd, an Australian company. In our price data Hotelscombined.com showed the same price as KAYAK.com at all 1,045 hotels where both were listed. Here is what we measured, and what to check before you book.

Measured, not sponsored: the numbers come from our own price snapshots. If you book through a link from Underbook we may earn a commission from the booking site you choose, at no cost to you, and it does not change what we show.

The verdict, in plain terms

A legitimate search site owned by Booking Holdings. In our data its price was KAYAK's every time, so treat the two as one quote, and compare totals after tax.

What is true in its favor

  • Owned by Booking Holdings since December 2018, reporting into KAYAK, per Booking Holdings' announcement
  • A named company: HotelsCombined Pty Ltd (ACN 122 130 554), an Australian private company on the Australian Business Register
  • Listed at 1,115 hotels in 325 cities in our data

Why you should be careful

  • Its price was KAYAK.com's at all 1,045 hotels listing both, and momondo.com's at 810 of 811, so checking all three gives one price
  • Its Google Hotels price was often before tax: nearer the before-tax going rate at 318 of the 922 hotels where taxes added 10% or more
  • Its listings carried no free-cancellation label and named no room at any of the 1,115 hotels
  • The study recorded it as the lowest price at only 8 of 1,115 hotels

Read on October 2, 2026: HotelsCombined's terms of use (hotelscombined.com/terms-of-use) and About page, Booking Holdings' announcement of December 3, 2018 that it had completed the purchase (bookingholdings.com), and the Australian Business Register entry for ABN 61 122 130 554. They can change. HotelsCombined's other country sites appeared at 11 more hotels and are left out of the figures.

Measured, September 25 to October 1, 2026

HotelsCombined next to KAYAK and momondo

At the 1,045 hotels where Hotelscombined.com and KAYAK.com were both listed in our 14 price snapshots of September 25 to October 1, 2026, the two showed the same price every time. Next to momondo.com, another Booking Holdings search site, it showed the same price at 810 of 811. Hotelscombined.com was listed without KAYAK.com at only 70 hotels. See our KAYAK review and our momondo review.

Before tax or after

Where taxes and fees added 10% or more to a hotel's going rate (the price most sites agreed on), HotelsCombined's price sat nearer the before-tax going rate at 318 of 922 hotels. A before-tax price looks lower than another site's after-tax price for the same room. Next to Booking.com it showed the same price at 401 of 1,073 hotels. Where the two differed on the same tax footing, Booking.com was lower at 127 and HotelsCombined at 154; at 391 more the two prices could not be put on the same footing.

How often HotelsCombined had the lowest price

In the 14 price snapshots of September 25 to October 1, 2026 that recorded every booking site's price, we priced the same two-night stay at 5,830 hotels in 348 cities on every site Google Hotels listed. HotelsCombined was listed at 1,115 of them (621 in the US). The study recorded HotelsCombined as the lowest price at 8 of them, 8 of those 5% or more below the going rate (typically 9% below). At a further 238 it showed the same price as the listing recorded as lowest (when two sites show the same lowest rate, the study records the one Google listed first). For comparison, some site was 5% or more below the going rate at 4,181 of the 5,830 hotels, and Super.com was recorded as the lowest most often (1,193 hotels).

None of its listings carried Google's free-cancellation label or named a room, at any of the 1,115 hotels. A price with no room attached may be for the smallest or a non-refundable room, and you cannot tell from the listing.

These are prices from one moment in each snapshot, as Google Hotels showed them (all-in where the site reported taxes and fees, else the nightly rate), not completed bookings. Where two sites' prices differed, we say which was lower only when both were on the same tax footing (both before tax or both after), which we infer from the hotel's going rate with and without taxes, as on trivago vs Expedia. Method and the CSVs are on our hotel price study.

Before you book a HotelsCombined price, check four things

  • 1. One quote, not three. Hotelscombined.com showed KAYAK.com's price at all 1,045 hotels listing both and momondo.com's at 810 of 811, so add a booking site and the hotel's own site.
  • 2. Before tax or after. Its price on Google Hotels was often before tax. Compare the total after taxes and fees on the final booking screen.
  • 3. The room. Its listings in our data never named one. Compare the room name and bed type with the room you would book on the hotel's own site.
  • 4. Who takes your payment. Its terms call goods and services sold by another company a third-party offering and tell you to check its details before you accept it. Note which company takes your payment, and its cancellation terms.

Underbook (built by us) is a free Chrome extension that helps with the comparison while you shop. On a hotel page it shows other booking sites' prices for the same hotel and dates side by side, all-in where the sites report taxes and fees, and says whether a cheaper listing names the same room or needs a check before you book.
