Few things are more satisfying when planning a trip than landing cheap flights.
When it comes to finding a seat on domestic or international routes, there are often plenty of good deals on offer.
The only issue can be finding them.
Here are some of the best travel websites to do just that.

Kiwi.com

Kiwi.com is one of the best flight booking sites we’ve found, perfect for travellers who like to travel hack.
One of their tag lines is, “We hack the system, you fly for less”.
Of course, they don’t hack any systems - they just find you the best deals and hacks that other websites don’t.
Kiwi.com has so many great tools to uncover cheap flight deals.
Some of these include:

• The ability to book return flights with different airlines. For example, taking an outbound flight to Singapore with Singapore Airlines and returning on Qantas.

• Pricing tables and trends. These allow you to quickly see the cheapest days to fly within three days on either side of your intended departure and return dates.

• Best, Cheapest, Fastest. These tabs at the top of the results pages allow you to sort options by what matters most to you. If you want the cheapest option, select ‘Cheapest’. If you don’t want to stuff around in getting to your destination, choose ‘Fastest’. The ‘Best’ option provides a balance.

• Price Alerts. If you want to monitor prices for a trip you are planning, hit the ‘Set up price alerts’ button to receive alerts when prices for a route change.

• Fly ‘Anywhere’. If you have some annual leave booked but are looking for inspiration on where to go, you can put your departure airport in the ‘From’ box and ‘Anywhere’ in the ‘To’ box to search for the cheapest seats on domestic and international routes worldwide.

• Return ‘Anytime’. If you are not on a tight schedule for your trip, you can find cheaper seats by leaving the return date box blank during your search. This will find the best options for a range of trip lengths, whether it be for five nights or 20 nights away.

• Price lock. If you find a great deal but are not quite ready to book, you can lock the price for up to 72 hours for a small fee. You will pay the new, lower price if the price drops further during that time.

There are also some ‘hacks’ on Kiwi.com which you won’t find on other sites, including:

• Self-Transfer hack. This allows you to book individual flight legs with the same or different airlines for layovers if you are willing to collect your bags and check in again.

• Hidden city hack. Airlines might sometimes offer cheaper pricing for a multi-leg flight than a single-leg flight. This hack helps you find such situations. For example, if a flight from Sydney to Phuket (via Singapore) is cheaper than the same seat from Sydney to Singapore, you can book the flight to Phuket and get off in Singapore if you are travelling with only carry-on luggage.

• Throwaway ticketing. Airlines can sometimes offer return tickets for less than one-way tickets on international routes. This hack helps you find those offers more easily and ‘throw away’ your return ticket if you are taking an extended trip and are not sure when you’ll be back.

Overall, Kiwi.com is a great website to check out if you are searching for cheap flights.

Skyscanner

Skyscanner is one of the best-known flight search engines.
It searches and compares seat prices across many different booking websites to help you find the best deals.
Prices can vary between different booking sites, which is why Skyscanner can be a valuable tool.
For example, in March 2025, when we searched for a return flight between Sydney (SYD) and London (LHR) in Economy on Etihad Airlines, Skyscanner found one website where we could book for $1346.
Etihad’s own website was offering the same seat for $1501.
That’s a handy saving of $155 – or 11.5 per cent per return ticket.

Google Flights

Like Skyscanner, Google Flights lets you compare prices across many flight booking sites.
It can also show you historical pricing for a specific flight and whether pricing is currently low, normal or high.
Additionally, you can track prices through email notifications.
Bookings are not made through Google, with Google Flights instead forwarding you to airline or travel company websites to lock in the deal.

Summary

Kiwi.com offers unique search options like “Anywhere” and “Anytime” to find deals, along with opening up travel hacks for one-way and multi-leg trips. Skyscanner and Google Flights are other handy flight search engines that search and compare prices across different travel websites to help you find cheap flight deals.
