Best Google Flights Alternative to Find Cheap Flights

Google Flights is fast, free, and one of the most useful tools for comparing airfare. But it does not cover every type of flight search, and depending on how you travel, another platform may be a better fit.

Below, we compare six Google Flights alternatives, what each one does differently, what it costs, and when it is worth using.

Why Look for a Google Flights Alternative?

Google Flights is primarily a flight search and comparison tool. That makes it excellent for many searches, but there are situations where another platform may offer something different.

• Booking directly through a platform: Google Flights generally sends you to an airline or travel agency to complete your booking rather than selling the ticket itself.
• Searching with points and miles: Google Flights is primarily designed around cash fares, so travelers looking specifically for award availability may need a dedicated points search tool.
• Finding deals without a specific trip in mind: You can track prices for flights you are interested in, but other services can proactively alert you to cheap fares from your preferred airports.
• Getting more support for complex itineraries: Some search results can involve separate tickets or self-transfers. Travelers who want additional protection or support may prefer a platform designed around those types of bookings.
• Finding specialized fares: Some platforms focus on unconventional fare types or booking strategies that you generally will not find through Google Flights.

These gaps do not necessarily make Google Flights a worse option. They simply mean the best alternative depends on what you need from your flight search.

Best Google Flights Alternative to Find Cheap Flights

1) RatePunk

RatePunk is our own flight deals subscription. You choose the airports you would fly from, and RatePunk tells you about cheap fares as they appear, including the mistake fares that vanish within a few hours. It is not a search engine. There is no box to type a route into, and RatePunk never sells you the ticket.

• What you get - alerts for cheap flights from your airport, each with a deal score and a link to whoever is selling the fare.
• What it costs - $17.68 to $23.99 for the first year, then $104 a year on renewal. RatePunk is the only entry here you pay for before booking anything. There is a 14-day money-back guarantee and no free trial.
• What travelers think: RatePunk has a 4.2 out of 5 rating on Trustpilot from more than 7,000 reviews.
• Why choose it over Google Flights: RatePunk works differently from a traditional flight search. Instead of waiting for you to choose a route and dates, it finds cheap fares from your selected airports and sends them to you. It is a better fit when you are flexible and want the deal to help decide where or when you travel.

2) Skyscanner

Skyscanner is a flight search engine, owned by Trip.com Group since 2016. Like Google Flights it shows the fares and sends you elsewhere to buy, but it reaches further into small agencies, which is where the odd cheap fare turns up.

• What you get - fares from hundreds of airlines and agents, price alerts, and an “Everywhere” search that shows the cheapest destinations from your airport when you have no fixed plan.
• What it costs - free. Providers pay for the click.
• What people say - 4.4 out of 5 from about 22,700 Trustpilot reviews.
• Where it stops working - it leaves baggage out of the price it shows, which is the one thing Google Flights does better. And the fare belongs to whoever Skyscanner sends you to: its terms say your refund lies with them rather than with Skyscanner, and the quality of those agencies varies.

3) Momondo and Kayak

These two are one company. Booking Holdings owns both, and Momondo is run inside the Kayak division on the same platform, so checking one after the other is not a second opinion. Both are search engines that hand you off.

• What you get - Momondo folds baggage fees into the prices on its first results screen, which almost nothing else does, and it searches more than a thousand airlines and travel sites. Kayak adds a price forecast that tells you to buy or wait, and “Hacker Fares”, which build a return out of two separate one-way tickets.
• What it costs - free.
• What people say - Kayak 4.0 out of 5 from about 4,100 Trustpilot reviews, Momondo 1.2 out of 5 from about 1,700. Two scores that far apart inside one division is a good reminder that the number mostly measures whether a company chases reviews.
• Where it stops working - a Hacker Fare is two bookings rather than one, so a delay on the first leg leaves the second airline owing you nothing and your bags uncheckable. Both send you to third-party agencies that own the refund.

4) Kiwi.com

Kiwi.com is an online travel agency that stitches together flights from airlines that do not sell connections to each other, and adds trains and buses. It sells you the ticket. General Atlantic has held a majority stake since 2019.

• What you get - routings nothing else will build, a multi-city planner called Nomad that reorders your destinations to find the cheapest sequence, and a price lock that holds a fare for 72 hours.
• What it costs - a service fee on top of the fare. The price lock costs 10% of the ticket up front, and if the fare rises Kiwi covers the increase only up to about 200 euros.
• What people say - 4.0 out of 5 from about 199,000 Trustpilot reviews, the largest sample here. The pattern at the Better Business Bureau concerns refunds from canceled flights reaching Kiwi and not reaching the passenger.
• Where it stops working - a stitched itinerary is separate tickets, and Kiwi says so itself: the airlines are not obliged to put you on another flight if a delay makes you miss the next leg. Your protection is Kiwi’s own guarantee, paid in credit, rather than an airline’s duty of care.

5) Alternative Airlines

Alternative Airlines is a British travel agency that issues tickets itself, accredited to do so by the airline industry’s own body. What makes it worth knowing is not the price but the payment: it is the one place that will take almost anything.

• What you get - more than 600 airlines on its own count, over 40 ways to pay including installment plans and cryptocurrency, and prices in more than 160 currencies. If your card keeps being declined by airline sites abroad, this is the workaround.
• What it costs - a service fee built into the price, and the amount is published nowhere. Changing or canceling costs $96 a person unless you buy the roughly $26 service package at checkout that waives it, and the service fees are not refundable even on a refundable ticket.
• What people say - 4.9 out of 5 from about 31,700 Trustpilot reviews, the highest score on this page, with a five percent tail of one-star reviews.
• Where it stops working - its terms disclaim liability for delays and cancellations, so if the airline cancels, the fee is still gone. There is no 24-hour support line, and a change has to go through the agency rather than the airline.

6) Skiplagged

Skiplagged is a booking site built around hidden-city fares. You buy a ticket from A to C that connects at B, then get off at B, because the longer ticket is cheaper than the short one. It is the one thing on this page Google Flights will never show you.

• What you get - itineraries no search engine surfaces, because the airlines would rather they were not found.
• What it costs - a service fee on top of the fare, shown at checkout but published nowhere in advance.
• What people say - 4.5 out of 5 from about 800 Trustpilot reviews.
• Where it stops working - American and United both ban hidden-city ticketing in their contracts of carriage, and both reserve the right to cancel the rest of your itinerary, close your frequent flyer account, and bill you the difference. You cannot check a bag in any case, because it would travel to the ticket’s final destination rather than yours. Airlines that have sued passengers over it have lost, so the exposure is commercial rather than legal, but an airline canceling your flight home does happen.

7) Expedia

Expedia is an online travel agency that sells the ticket itself and bundles flights with hotels and cars. Expedia Group also owns Orbitz, Travelocity, and Hotwire, and runs them on one platform, so the four are one opinion in four skins.

• What you get - package deals, and free cancellation within 24 hours on bookings that carry the badge for it.
• What it costs - fees are bundled into the fare rather than itemized.
• What people say - 1.2 out of 5 from about 12,500 Trustpilot reviews. Expedia does not solicit reviews, which is part of why the number looks like that.
• Where it stops working - One Key stopped earning anything on flights in July 2026 and the hotel price guarantee went with it, so the loyalty case for booking flights here is thinner than it was. The 24-hour cancellation is Expedia’s own offer rather than a legal right, it applies on the American site to bookings made at least a week ahead, budget airlines are excluded, and a refund can take two billing cycles to arrive.

Insider Tips for Booking Cheap Flights

Most of the booking tricks that circulate have no figures behind them. These do.

• The month beats the day - flying in August rather than December saves about 29%, roughly $120 a ticket, on Expedia’s figures. The cheapest day of the week to buy is worth 2% to 3%, which is inside the noise.
• The day you fly is worth more than the day you book - leaving on a Friday rather than a Sunday runs about 8% cheaper internationally, and a Tuesday rather than a Sunday about 14% on domestic routes.
• Book inside the window, not as early as you can - Expedia puts a domestic economy seat about $130 cheaper at 15 to 30 days out than at six months. Google puts fares from the US to Europe lowest at 72 days or more. They disagree, which is the honest answer: there is no single correct date.
• Clearing cookies and browsing in incognito does not work - Consumer Reports ran 372 searches and found the price identical 88% of the time, with incognito more expensive as often as it was cheaper. We said the same in the Washington Post in 2023: booking sites read your location to set your currency and language, not to move your fare.
• Check the airports around you - this one is free and it is often the largest single saving on the list, particularly in Europe, where a second airport is usually under an hour away.

Which One to Use

The right Google Flights alternative depends on what you need from your search. If you already know your destination and dates, Google Flights is still a useful place to compare fares before checking your options elsewhere.

Other tools make more sense for specific needs. Kiwi.com can help you explore more complex or self-transfer itineraries, Alternative Airlines offers a wide range of payment options, Skiplagged specializes in finding hidden-city fares, and Momondo gives you another way to compare prices across airlines and booking sites.

RatePunk takes a different approach. If your plans are flexible, you do not necessarily need to search for a specific trip at all. Choose your departure airports and RatePunk sends cheap flight deals to you, making it particularly useful when the price of the trip could help decide where and when you go.
