Skyscanner vs Kayak: Which Flight Search Tool Wins?
Skyscanner and Kayak are both powerful flight search engines, but the right choice depends on your priorities: Skyscanner excels at finding the cheapest flights, especially for budget airlines and flexible dates, while Kayak offers more robust filtering, price prediction, and a cleaner interface for comparing options. This article breaks down their key differences to help you decide which one to use for your next trip.
Background: What Are These Tools?
Both Skyscanner and Kayak are metasearch engines—they don’t sell tickets themselves but aggregate flight results from hundreds of airlines and online travel agencies (OTAs) like Expedia, Booking.com, and budget carriers. This means they can show you a wide range of options in one place, saving you from checking multiple websites individually.
Skyscanner was founded in 2003 in Edinburgh, Scotland, and has a strong presence in Europe and Asia. Kayak, launched in 2004 in the US, is part of Booking Holdings (which also owns Priceline and Booking.com). Both have mobile apps and are free to use—they earn money through referral fees when you book through their links.
How They Work: The Mechanics of Searching
When you enter your trip details, both tools scan their databases of flight prices and display results in seconds. The key difference lies in their search flexibility:
- Skyscanner shines with its “Everywhere� search—you can enter your departure city and see the cheapest destinations worldwide. It also allows you to search for a whole month or even a year, using a bar chart to show the cheapest days to fly.
- Kayak offers a “Hacker Fares� feature that combines two one-way tickets from different airlines to create a cheaper round-trip. It also has a “Price Forecast� tool that uses historical data to advise whether to book now or wait for a lower price.
Both let you filter by airline, number of stops, departure time, and price. Kayak’s filters are slightly more granular (e.g., you can filter by specific baggage allowance or aircraft type), while Skyscanner’s are simpler and more user-friendly for beginners.
Choosing the Right Tool for Your Needs
The best choice depends on what you value most. Here’s a quick guide:
- If you’re flexible with dates or destinations: Use Skyscanner. Its “Everywhere� and month-view features are unmatched for finding the cheapest time to travel.
- If you want price predictions and fare hacks: Use Kayak. Its Price Forecast and Hacker Fares can save you money if you’re open to unconventional combinations.
- If you’re booking a simple round-trip on a specific date: Both work equally well. Try both and compare—prices can differ slightly due to which OTAs are included in the results.
A common strategy is to use Skyscanner to find the cheapest route, then check Kayak for the same route to see if it offers a better price or additional filters. Neither tool charges a fee, so it costs nothing to check both.
Common Problems and How to Avoid Them
Metasearch engines have a few quirks you should know about:
- Fake or misleading prices: Sometimes the price shown is for a basic fare that doesn’t include baggage or seat selection. Always check the fare rules before booking.
- OTAs with poor customer service: Booking through a third-party site can be risky if your flight changes or gets canceled. If you want peace of mind, book directly with the airline, even if it costs a bit more.
- Missing budget airlines: Some low-cost carriers (like Ryanair or Southwest) don’t always appear in metasearch results. Check the airline’s own website if you have a specific carrier in mind.
To avoid these issues, always read the fine print, compare the final price (including baggage and seat fees) with the airline’s own site, and consider booking directly for international or complex itineraries.
Comparison: Skyscanner vs Kayak at a Glance
| Feature | Skyscanner | Kayak |
|---|---|---|
| Best for flexible dates | Yes (month/year view) | Limited (only shows a few days) |

| Hacker Fares (combining one-ways) | No | Yes |
| “Everywhere� search | Yes | No |

This table shows that Skyscanner is more geared toward spontaneous travelers, while Kayak appeals to those who want more control and data.
Costs and Safety: What You Need to Know
Both tools are completely free to use—they don’t charge you a booking fee. However, the prices they show may include or exclude taxes and fees, so always check the final price before paying.
In terms of safety, both are legitimate companies with millions of users. The risk lies in the third-party OTAs they link to. To stay safe:
- Look for OTAs with good reviews and a clear refund policy.
- Use a credit card for payment, which offers more fraud protection than a debit card.
- Double-check the airline’s name and flight number before completing the purchase.
If you ever feel unsure, book directly with the airline. The peace of mind is often worth the extra few dollars.
Alternatives to Consider
If neither Skyscanner nor Kayak feels right, there are other metasearch engines worth trying:
- Google Flights: Fast, accurate, and great for exploring destinations. It also shows price trends and can track prices for you.
- Momondo: Owned by Kayak, but with a more colorful interface and a “flight insight� feature that shows price history.
- Dohop: Specializes in self-connecting flights, which can be cheaper if you’re willing to take the risk of missing a connection.
Each tool has its strengths, so it’s worth experimenting to see which one best matches your travel style.
Frequently Asked Questions
Which is cheaper, Skyscanner or Kayak?
Neither is consistently cheaper—they both search the same airlines and OTAs. However, Skyscanner’s flexible search often uncovers cheaper dates, while Kayak’s Hacker Fares can reduce costs on specific routes. The best approach is to check both for your specific trip.
Can I book directly on Skyscanner or Kayak?
No, they are metasearch engines. When you select a flight, you’re redirected to the airline’s or OTA’s website to complete the booking. This is why it’s important to read the fine print on the final page.
Do Skyscanner and Kayak show budget airlines like Ryanair or Southwest?
Skyscanner includes many budget airlines, but some like Ryanair may not appear. Kayak also includes some, but Southwest is often excluded because it doesn’t participate in metasearch. Always check the airline’s own site for the most accurate availability.
Is it safe to book through the third-party sites they link to?
Generally yes, but it depends on the OTA. Stick to well-known ones like Expedia, Booking.com, or the airline’s own site. If a deal looks too good to be true, it probably is—check reviews before booking.
Which app is better for mobile?
Both apps are highly rated. Skyscanner’s app is more intuitive for casual travelers, while Kayak’s app offers more advanced filters and price alerts. Try both to see which interface you prefer.
