The Best Cheap Flights Websites Nobody Talks About
1. Kayak
Kayak remains a go-to tool in 2025 for comparing flights, thanks to its data-driven approach. One standout feature is "Hacker Fares", which pairs one-way tickets from different airlines to create cheaper options compared to traditional round-trip bookings [4].
Kayak uses its massive search data to predict flight prices with impressive accuracy. Its user-friendly tools, like the 'Explore' feature, make finding destinations and planning trips easier. Some of its key offerings include:
- Real-time price alerts for specific routes
- Detailed filters for flight duration, layovers, and more
- Itinerary management tools to track flight changes and organize bookings
- Built-in trip planning for flights, hotels, and transportation
The platform’s price tracking feature notifies users of fare drops, helping them lock in the best deals. For example, February 2025 is expected to offer discounted fares - up to 15% lower - for destinations like Saint Lucia, Egypt, and Thailand [7].
However, Kayak does have a couple of drawbacks. It redirects users to third-party booking sites, which can sometimes include extra fees, and its ads may feel distracting to some [4]. Still, these are minor issues compared to the platform's wide range of features. By combining flights, accommodations, and transportation into one seamless system, Kayak offers a convenient way to plan and save on travel [1][4].
While Kayak excels in affordability and ease of use, other platforms such as Google Flights also bring unique tools to the mix.
2. Google Flights
Google Flights is a go-to tool in 2025, thanks to its easy-to-use design and powerful features. It offers a range of filters, letting users refine searches by airline alliances, layovers, and trip duration [4]. With tools like the date grid and price graph, travelers can quickly identify cheaper travel dates and spot seasonal fare patterns [1].
Unlike Kayak, which leans toward all-in-one travel planning, Google Flights focuses on clear pricing and helpful insights. Its price tracking feature keeps an eye on fares around the clock, sending alerts when prices drop significantly. The 'Explore destinations' tool makes it simple to search based on budget, flexible dates, and personal interests, all with real-time updates.
Although bookings are completed through external platforms, Google Flights integrates well with other Google tools. It ensures all costs are shown upfront, eliminating unexpected fees [4]. Plus, the connection with Google Maps provides useful details about airports and destinations, making trip planning even easier [4].
While Google Flights shines with its clear pricing and predictive features, Momondo stands out for finding hidden deals and specialized options.
3. Momondo
Momondo is a go-to platform for finding hidden travel deals across hundreds of websites. It offers advanced filters to fine-tune searches by departure times, layovers, and price ranges, making it a favorite for budget travelers looking to save [1].
One standout feature is its price tracking tool, which keeps an eye on fare changes for specific routes and sends instant alerts when prices drop [1][4]. Momondo's search algorithm dives deep, scanning both well-known airlines and smaller carriers. This often uncovers routing options that other tools might miss. By simplifying complex searches and delivering clear results, it helps users make smart travel choices without hassle.
Momondo's reputation in flight comparison is well-earned. A satisfied user shared:
"Momondo's comprehensive search capabilities and ability to find the cheapest flights have made it one of the top flight comparison sites in 2025" [1]
Beyond flights, Momondo also supports hotel bookings and car rentals, offering a one-stop solution for travel planning [1][4].
Its mobile app mirrors the desktop experience, complete with multi-language support for over 30 markets, making it a reliable companion for international travelers.
Next, we'll dive into Skyscanner and its standout features, like the 'Everywhere' search, that make it a leader in flight comparisons for 2025.
4. Skyscanner
Skyscanner attracts over 100 million users each month across 180 countries, making it a top choice for flight comparisons in 2025 [5]. Its standout features, like the 'Everywhere' and 'Whole Month' search options, help budget travelers uncover the lowest fares and the best dates to travel [5][6].
For those planning complex trips, Skyscanner’s multi-city search tool offers detailed results. The platform also includes advanced filters, allowing users to refine searches based on flight duration, airline alliances, number of stops, and departure times - perfect for meeting a variety of travel needs [3][4].
One of Skyscanner’s key strengths is its price tracking feature, which uses historical data and AI to identify the best times to book. This has become a go-to tool for flexible travelers, with the Horizons Report noting that 48% of travelers now rely on such data-driven insights for planning [3].
The platform goes beyond flight comparisons by integrating with travel services and marketing organizations, creating a smooth booking process from start to finish [3]. Its mobile app mirrors the desktop version, offering features like Price Alerts to ensure users stay updated on fare changes [6].
While Skyscanner delivers flexibility and global reach, Hopper pushes the envelope further with predictive analytics and tailored recommendations.
5. Hopper
Hopper has made a name for itself in 2025 with its AI-driven price prediction tools. By analyzing past airfare trends, the platform helps users pinpoint the best times to book flights and lock in great deals [4].
Key features like 'Flex Watch' and 'Price Drop Alerts' are designed to save travelers both time and money. These tools monitor prices across multiple travel dates, notifying users when it's the right moment to book. With these insights, users can cut flight costs by as much as 40% [4]. For those with flexible schedules, 'Flex Watch' is particularly useful, as it tracks prices across a range of dates to find the cheapest options.
Hopper's AI tools go a step further by tailoring booking recommendations to individual users, sending instant alerts for deals that fit their travel preferences. Its mobile-first design makes it easy to manage plans on the go, while the 'Carrot Cash' rewards program offers cashback on bookings - perfect for frequent flyers looking to save even more.
The platform also partners with airlines to provide exclusive deals, setting it apart from other flight comparison tools that focus solely on current prices. Hopper’s approach emphasizes long-term savings through smart, data-backed decisions.
For travelers who prefer last-minute adventures over careful planning, platforms like GTFO.co offer a completely different way to compare flights.

6. Expedia
Expedia is a popular platform for travelers, offering flight comparisons and travel deals in over 70 countries. One of its key features is the ability to bundle flights, hotels, and car rentals into a single booking, which can help users save money.
The platform's layout allows users to easily compare various travel options at once, making it simpler to plan and manage overall trip costs.
| Feature | What It Offers |
|---|---|
| Bundle Savings | Discounts by combining flights, hotels, and car rentals |
| Rewards Program | Points that can be redeemed for future travel |
| Price Match | Ensures competitive rates |
| Mobile App | Convenient booking management anytime |
Expedia includes price tracking, but the standout feature is its bundling option, which can lead to major savings. The mobile app is especially convenient, with half of all bookings now made through mobile devices [4].
For those dealing with itinerary changes, Expedia provides 24/7 customer support to handle rebooking, refunds, or adjustments. This service is especially helpful for complex travel plans.
The Rewards Program is another perk, allowing users to earn points on bookings that can be used for future discounts. To get the most out of Expedia, enable price alerts to stay updated on fare changes, and always compare bundle deals with individual bookings to find the best value. Flexible travelers can also check out the last-minute deals section for additional savings.
While Expedia is a great all-in-one travel tool, experienced users looking for deeper fare analysis might prefer platforms like ITA Matrix.
7. ITA Matrix
ITA Matrix, created by Google, is a flight search engine offering detailed flight analysis for travelers who want precise control over their travel plans. While it’s not as straightforward as mainstream booking platforms, it’s a go-to tool for frequent flyers and business travelers who need in-depth options.
What sets ITA Matrix apart is its advanced search capabilities, such as:

For frequent flyers and business travelers, the ability to access detailed fare class information is a major plus. ITA Matrix is directly connected to airline booking systems, so its pricing and availability data are always current. However, it’s important to note that you can’t book flights directly through the platform [1].
The platform’s filtering tools are ideal for organizing complicated travel plans, like multi-city itineraries or specific route preferences. With ITA Matrix, you can:
- Use routing codes to mix and match airlines for cost-effective trips
- Compare fare classes across dates to find the best deals
- Search by airline alliances to maximize loyalty program benefits
Although the interface can be tricky to navigate at first, the level of detail and control it offers makes it an essential tool for anyone needing advanced flight search options. In the next section, we’ll see how ITA Matrix stacks up against more user-friendly platforms [1][4].
