Google Flights is the best overall flight price tracker for most people in 2026. It's free, easy to use, and sends email alerts when fares change. If you want to discover cheap flights without having a destination in mind, Skyscanner and Going are excellent alternatives.
The 5 best flight price trackers
1. Google Flights
(Best overall)
Free
Track a specific route or exact flight, compare dates on a price calendar, and receive alerts when prices change significantly. Best for knowing when to book a trip you've already planned.
Track flights at Google Flights
2. Hopper
Free app; optional paid features
Predicts whether fares may rise or fall and suggests whether to buy now or wait. Helpful if you're trying to time a purchase, but predictions aren't guaranteed.
3. Skyscanner
Free
Best for flexible travelers. Search an entire month or select “Everywhere” to find inexpensive destinations, then set price alerts. Double-check the final fare before booking.
4. Going
Free and paid memberships
Best for discovering flight sales, unusually cheap fares, and mistake fares from your preferred departure airports. It sends you deals rather than tracking only one itinerary.
5. KAYAK
Free
A solid alternative for price alerts, fare comparisons, and managing other travel bookings in one place.
Which one should you use?
Your goal Best choice Track prices for a planned trip Google Flights Predict whether to book now or wait Hopper Find the cheapest destination Skyscanner Get surprise flight deal alerts Going Compare flights and other travel KAYAK My recommended strategy
- Search your trip on Google Flights and turn on Track prices.
- Set a second alert on Skyscanner or KAYAK.
- If you're flexible about destinations, subscribe to Going's free alerts.
- When a good fare appears, check the airline's own website before purchasing.
Google's official instructions confirm that you can track specific flights or routes, including any dates when your travel dates are flexible.
One quick question: What kind of flights do you usually track?
A specific route and travel dates
A destination, but flexible dates
Any cheap flight deals from my home airport
Budget for the tracker
Free only
Paid is okay if it finds better deals

Google Flights is the best overall flight price tracker because of its unmatched speed, clean interface, reliable email notifications, and predictive price-rise insights.
Other specialized tools excel depending on your specific booking style and flexibility.
Top Flight Price Trackers Compared
Tracker Best For Key Strengths Limitations Google Flights Overall speed and reliability Instant price-drop emails, date grid/price graph, and machine-learning predictions on whether fares will rise. Requires you to manually toggle on tracking for specific routes or flexible dates. Skyscanner Budget and international carriers Massive airline coverage, including independent and low-cost regional carriers that major aggregators miss. Push notifications and alert emails can occasionally lag behind real-time price changes. Hopper Predictive buying advice Color-coded calendar telling you whether to buy now or wait , plus an option to freeze fares. Predictions are not 100% accurate and waiting can occasionally backfire if fares spike. KAYAK Fast multi-channel alerts Price forecasting trends combined with reliable push and email notifications. Interface can feel cluttered with third-party online travel agency (OTA) ads. How to Choose the Right Tracker
- Use Google Flights if you want clean data straight from the airlines, fast page-load speeds, and notifications telling you if a fare is likely to go up before you purchase.
- Use Hopper if you are flying a popular route and want an automated recommendation on whether to book immediately or gamble on a price drop.
- Use Skyscanner if you are hunting for cheap, multi-leg, or budget-airline connections outside major carrier networks.
If you'd like, let me know:
- Your origin and destination cities
- Your approximate travel dates (or if you are flexible)
I can set up a task to monitor or help you evaluate the best options for your route.

The best flight-price tracking apps in 2026 are Google Flights, Skyscanner, Hopper, and KAYAK. They let you monitor fares and get alerts when prices change, but they differ in how they help you decide when to book.
My recommendation: start with Google Flights for free price alerts, then add Skyscanner or Hopper if you want another way to monitor fares.
Top flight-price tracking apps
1. Google Flights
(Best overall)
Free · Web-based

Track flights on Google Flights

Best for: Finding cheaper alternatives and comparing multiple dates.
3. Hopper
Free app · Optional paid features
Uses historical pricing trends to estimate whether fares may rise or fall. Sends notifications with “buy now” or “wait” recommendations; some price-hold features cost extra. Predictions aren't guaranteed.

Which one should you choose?
If you want to… My pick Track a particular flight for free Google Flights Compare dates and destinations Skyscanner Get buy-now-or-wait guidance Hopper Manage alerts and trips together KAYAK Discover deals without searching constantly Going My money-saving strategy
- Set up Google Flights alerts for your desired route and dates.
- Add a Skyscanner alert for the same trip to cross-check prices.
- If your dates are flexible, compare nearby departure dates and airports.
- When a fare drops to a price you're happy with, verify it on the airline's official website before booking.
No tracker guarantees the lowest fare, and price forecasts can be wrong. Using two services gives you a better chance of catching a worthwhile deal.
Want me to narrow it down? Are you tracking a specific flight with set dates, or are you flexible and looking for the cheapest possible trip?
