If your trip is coming up soon, the best way to save on airfare is to compare multiple flight search sites, keep your travel dates flexible if possible, and check nearby airports. You can often find cheaper options without sacrificing too much convenience.
Best websites to find cheap flights
1. Google Flights
Best overall for comparing prices

Search flights on Google Flights
2. Skyscanner
Best for flexible destinations and dates

3. KAYAK
Best for comparing different booking options

4. Going

How to get the lowest fare
- Compare at least two sites. Start with Google Flights, then cross-check Skyscanner or KAYAK. No single site always finds the cheapest ticket.
- Try nearby dates and airports. Even shifting your departure by a day or checking a nearby airport may help.
- Compare the final total. Include baggage, seat fees, airport transfers, and any booking fees.
- Check the airline's own website before paying. It can be easier to handle changes or cancellations when you book directly.

Finding cheap flights comes down to
using the right aggregators, being flexible, and knowing where to look. Here are the best tools and platforms to help you secure a great deal:- Google Flights : Great for fast, clean calendar comparisons, tracking price drops for specific routes, and seeing how your dates affect the total cost. Visit Google Flights to start searching.
- Skyscanner : Excellent for searching "Everywhere" if you are flexible on your destination and want to see the cheapest places to fly from your home airport. Check options on Skyscanner.
- Kayak : Useful for comparing multiple booking sites at once and using their "Hacker Fares" which combine two one-way tickets on different airlines for a cheaper round trip. Explore deals on Kayak.
- Hopper : A mobile app that predicts whether flight prices will go up or down and tells you whether to buy now or wait. Learn more on Hopper.

Finding cheap flights isn't about using just one "magic" website—it’s about using the right tool for each stage of your search.
The Top Flight Search Engines
- Momondo : Frequently ranks #1 for overall price discovery and excels at pulling in smaller third-party providers alongside major airlines, often uncovering hidden savings.
- Skyscanner : The gold standard for flexibility. Use their "Whole Month" or "Cheapest Month" grids, or search "Everywhere" if you just want to see where is cheapest to go right now.
- Google Flights : Unmatched for raw speed and date-grid clarity. Its interactive Explore map is the best way to visually hunt for cheap destinations, and you can turn on Price Tracking to get emails when fares drop.
Pro-Tips to Maximize Savings
- Be flexible with dates and places: Flying on Tuesdays, Wednesdays, or Saturdays usually shaves a chunk off the price.
- Cross-check your results: Search your route on Momondo or Skyscanner first to find the cheapest aggregate options, then double-check the final price on Google Flights.
- Book direct: Once you find the itinerary you want, always click through to book directly with the airline rather than a sketchy third-party agency. It makes managing cancellations or delays infinitely easier.
If you have a specific trip in mind, tell me your origin city, destination or general region , and approximate dates , and I can help you search or set up a task to track price changes.

The best place to start finding cheap flights is Google Flights, then compare prices on Skyscanner before booking. No single website is always the cheapest, so checking two or three can help you find a better fare.
Best websites for cheap flights
1. Google Flights — Best overall
Free · Best for comparing dates and airports
Quickly compare fares, view cheaper travel dates on a calendar, explore destinations and set price alerts.
2. Skyscanner — Best for flexibility
Free · Best if you're open to different destinations or dates
Its “Everywhere” search helps you discover destinations with low fares, and flexible-date searches can reveal cheaper days.
3. KAYAK — Best for a second price check
Free search · Provider comparisons and price alerts
Check whether another airline or booking agency offers a lower price for the same itinerary.
4. Going — Best for surprise deals
Free and paid options · Primarily U.S. departure airports
Sends flight-deal alerts so you can discover bargains without repeatedly searching. Some features require a paid membership.
These recommendations reflect the sites' different strengths, not a guarantee that one will always return the lowest fare.
My trick for getting the lowest price
- Search your trip on Google Flights first.
- Compare the same dates on Skyscanner and KAYAK.
- Turn on price tracking if you're not ready to book.
- Try departing a day or two earlier or later, and check nearby airports.
- Before paying, check the airline's own website and compare baggage fees and the final total. Booking direct can also make changes easier.
