Finding an affordable flight can be the hardest part of trip planning, but the right technology makes it simple. In 2025, several key apps can help you find amazing deals and save money on your next adventure. This guide Onward Free will break down the top Best Flight Ticket Apps and share essential strategies to help you fly for less.

Top Best Flight Ticket Apps for Budget Travelers in 2025

The best app for you will depend on your travel style. Some excel at finding the absolute lowest price by combining different airlines, while others predict price drops or offer savings on package deals. Here are the must-have apps for any budget-conscious traveler in 2025.

1. Skyscanner

Skyscanner remains a powerhouse in the world of cheap flights due to its incredible flexibility. Its “Everywhere” search feature is perfect for travelers who want to go on an adventure but don’t have a specific destination in mind—it shows you the cheapest places you can fly to from your home airport. Additionally, its “Whole Month” or “Cheapest Month” view allows you to instantly spot the lowest-priced days to travel, saving you hours of manual searching. With powerful filters and reliable price alerts, Skyscanner is an essential first stop and one of the Best Flight Ticket Apps for any flight search.

Pros	Cons
Great, easy-to-use search engine that finds cheap fares.	Final price can be higher than what’s initially displayed.
“Anywhere” & “Entire Month” tools for flexible travel.
Compares prices across hundreds of sites, including small OTAs.

2. Hopper

Hopper’s standout feature is its data-driven price prediction. The app analyzes billions of flight prices to advise you on whether to “buy now” or “wait for a better price” with impressive accuracy. This takes the guesswork out of booking. For a small fee, you can also use Hopper’s “Price Freeze” feature, which locks in a fare while you finalize your plans. If the price goes up, Hopper covers the difference up to a certain amount; if it goes down, you pay the lower price. It’s an invaluable tool, making it one of the Best Flight Ticket Apps.

Pros	Cons
Accurate price prediction tells you when to buy.	Only available as a mobile app.
“Price Freeze” locks in fares for a fee.	Customer support can be hard to reach.
Earn “Carrot Cash” rewards for future bookings.	Limited search flexibility for dates/destinations.

3. Momondo

Momondo is a metasearch engine that consistently finds some of the lowest fares by scouring a vast range of sources, including many online travel agencies (OTAs) that other search engines miss. Its interface is clean and visually appealing, with bar graphs that show you how prices vary across different days. Momondo also provides helpful insights, such as how factors like the airline, time of day, and booking window affect the price for your specific route.

Pros	Cons
Transparent pricing with no hidden fees.	“Mix & Match” deals may require separate bookings.
Visual bar graphs show price trends.	Redirects to third-party sites of varying quality.
“Mix & Match” fares combine airlines to lower costs.

4. Kiwi.com

Kiwi.com has carved out a niche with its “virtual interlining” technology. It finds unique and often dramatically cheaper routes by piecing together separate flights from airlines that don’t have partnership agreements. This unique approach makes Kiwi.com one of the most innovative Best Flight Ticket Apps for creative travelers.

Pros	Cons
“Virtual Interlining” creates unique, cheap itineraries.	Poor customer service is a widely reported issue.
“NOMAD” feature is excellent for multi-city trips.	Hidden fees can increase the final price.
Kiwi.com Guarantee protects against some disruptions.	“Self-transfers” can be risky and inconvenient.

5. Kayak

As one of the original flight aggregators, Kayak continues to be a reliable and comprehensive tool. It searches hundreds of travel sites at once to give you a complete overview of your options. Kayak offers robust filtering, price alerts, and a price forecast tool that, similar to Hopper, advises you on the likelihood of fares rising or falling. It’s an excellent all-in-one platform for comparing flights, hotels, and car rentals.

Pros	Cons
“Hacker Fares” combine one-way tickets to save money.	No loyalty program for users.
Price forecast advises on the best time to buy.	Top search results can be sponsored.
Comprehensive search covers hundreds of sites.	It’s a search engine, not a direct booking site.

6. Trip.com

With a strong presence in the Asian travel market, Trip.com is an excellent resource for finding competitive fares on international routes, particularly to and within Asia. The platform is known for its clean interface, transparent pricing (taxes and fees are often included upfront), and a loyalty program called Trip Coins, which you can redeem for discounts on future bookings. It’s a rapidly growing platform that is increasingly competitive on a global scale.

Pros	Cons
Strong deals, especially for Asian flights.	Inconsistent customer service.
User-friendly interface and booking process.	Difficult to change or cancel bookings.
“Trip Coins” rewards program for future travel.

7. Expedia

Expedia is a giant in the online travel space, and its biggest strength lies in bundling. While you can book flights alone, you often unlock the most significant savings by packaging your flight with a hotel or car rental. For this reason, Expedia remains one of the most popular Best Flight Ticket Apps for bundled savings.

Pros	Cons
Significant savings with bundle deals (flight + hotel).	Cancellation policies can be confusing and restrictive.
“One Key Rewards” program works across multiple sites.	Fewer loyalty perks (airline miles, hotel points).
Convenient one-stop shop for all travel bookings.

8. Google Flights

Unmatched in speed and simplicity, Google Flights is a favorite tool and one of the Best Flight Ticket Apps for many travelers. Its intuitive calendar view and date grid instantly show you the cheapest fares over a two-month period. The “Explore” map is another fantastic feature, allowing you to see prices for destinations all over the world from your departure airport.

Pros	Cons
Incredibly fast, ad-free, and simple interface.	Doesn’t always find the lowest price as it omits smaller OTAs.
Powerful visual tools like Date Grid and Price Graph.	Can display “ghost fares” that are no longer available.
Reliable price tracking with historical data and alerts.

Tips for Using the Best Flight Ticket Apps Smartly

Having the right apps is only half the battle. To truly master the art of finding cheap flights, combine these tools with smart booking strategies:

• Be Flexible: If you can be flexible with your travel dates and even your destination, you will always find better deals. Use Skyscanner’s “Everywhere” search or Google Flights’ “Explore” map to discover affordable trips.
• Set Price Alerts: Never book the first fare you see. Choose your ideal route on multiple apps (like Google Flights, Kayak, and Hopper) and set up price alerts. Let the deals come to you.
• Book in the Sweet Spot: For domestic flights, the best prices are typically found 1–3 months in advance. For international travel, aim for 3–6 months out. Avoid booking too early or too late, as prices tend to be highest at these times.
• Check Alternate Airports: If your destination city is served by multiple airports, make sure to include them all in your search. A flight into a smaller, secondary airport can sometimes be significantly cheaper.
• Fly on Off-Peak Days: Flights on Tuesdays, Wednesdays, and Saturdays are generally cheaper than those on Fridays and Sundays, which are popular with both leisure and business travelers.
• Consider Bundling: If you also need a hotel or car, check prices on Expedia or other OTAs for a package deal. The bundled savings can sometimes be substantial.
• Secure Proof of Onward Travel: Many countries require you to show a return or onward flight ticket upon arrival. For one-way travelers or those with flexible plans, services like OnwardFree.com offer legitimate, verifiable onward tickets for a small fee, or free dummy tickets, satisfying immigration requirements without needing to buy a full-fare return ticket.
