1. Kiwi.com
If you’re the kind of traveler who’s flexible on the destination or doesn’t mind a quirky layover to save money, Kiwi is worth checking out. It lets you search from your city to “Anywhere”, which is perfect when you just want to see what’s cheap right now.
Why travelers like it:
- Shows routes that combine airlines that don’t usually work together
- Finds creative layovers (and usually saves you money)
- Has a guarantee that covers certain delays and missed connections
2. WayAway
If you’re the kind of traveler who likes getting money back on flights, hotels, and even activities—you’ll want to check out WayAway. It’s a flight search tool that offers cashback on bookings, but to unlock that feature, you’ll need their WayAway Plus membership.
It’s not free, but there’s a 7-day trial, and if you’re planning more than one booking (like flights + hotel), the cashback can easily pay for itself. Membership runs around $49.99/year, and it includes perks like 24/7 support and local travel guides too.
Here’s how it works:
- Sign up for a free account
- Start the 7-day WayAway Plus trial (no pressure—just explore it)
- If you like it, you can upgrade to full membership
- Cashback is credited via PayPal, and you can cancel anytime from your account
You can still use the flight search for free—WayAway Plus is just there if you want the extra perks.
Benefits:
- Cashback on flights, hotels, car rentals, tours
- Clean, easy-to-use interface
- 24/7 support and helpful local guides included
3. Trip.com – Especially Good for International Travel
Trip.com is especially popular with travelers booking flights in and around Asia or planning multi-country trips. It often shows routes and prices that don’t pop up on Google Flights or other major sites, especially for Asian and European destinations.
Why people use it:
- Great for less obvious flight routes
- Often includes luggage in the upfront price
- Smooth mobile-friendly platform

How to Book Cheap Flights in 2025
Finding cheap flights isn’t just about luck—it’s about knowing a few simple strategies that can save you hundreds. Here’s how to book smarter:
- Be flexible with your travel dates and destinations. Prices can vary wildly depending on the day of the week or time of year. Using tools like Kiwi.com’s “Anywhere” search can help you find the best deals.
- Search in private or incognito mode. Flight prices sometimes increase based on your browsing history, so this helps avoid price hikes.
- Book flights midweek or several weeks in advance. Tuesdays and Wednesdays are often cheaper, and booking 3–6 weeks ahead can get you better prices.
- Compare multiple flight search engines. No single site has all the deals. Using a mix of Kiwi.com, WayAway, Trip.com, and others can uncover hidden bargains.
- Check what’s included upfront, especially luggage fees. Some sites like Trip.com include luggage in the price, helping you avoid unexpected fees later.
Using these tips together with the right platforms will make booking cheap flights easier and less stressful in 2025.
4. Aviasales
Aviasales is often mentioned in travel groups and forums when people talk about budget flights in Europe or lesser-known carriers. If you’re hopping between cities or trying to save on short-haul routes, this one’s worth a look.
What stands out:
- Picks up regional and low-cost airlines
- Good filters for adjusting by stops, time, or airline
- Works fast and doesn’t feel overloaded with ads
5. Booking.com – For Booking Flights and Hotels in One Spot
Yes, Booking.com is known for hotels—but they’ve added flights, too. For travelers who like everything in one place (especially bundling hotel and flight bookings), this can be a convenient option to keep things simple.
Why it’s convenient:
- See hotel and flight options together
- Clear breakdown of what’s included
- No sketchy pop-ups or hidden fees
