7 Best Flight Price Trackers
in 2026
We tested every major flight price tracking tool — from Google Flights to dedicated trackers — and compared them on what actually matters: how often they check prices, how useful their alerts are, and whether they catch short-lived price drops.
Last updated: April 2026
Why Check Frequency Is the Most Important Feature
Most travelers focus on coverage or cost when picking a price tracker. But the single biggest differentiator is how often the tool checks prices.
Airfare price drops are often short-lived — many last only 2 to 6 hours before reverting. A tracker that checks once per day will see the price before and after the drop, but miss the window entirely. Hourly monitoring catches roughly 3–5x more actionable price drops than daily monitoring.
This is why we weight check frequency heavily in our comparison. A tracker that checks hourly and covers fewer routes is often more valuable than one that checks daily across every airline.

Detailed Reviews
Trip Manta — Best for Dedicated Price Tracking
Trip Manta is a purpose-built flight price tracker. It doesn't try to be a metasearch engine or a travel agency — it does one thing: monitor flight prices and alert you when they drop. The Pro tier checks every hour (24 times per day), which means it catches short-lived price drops that daily trackers miss.
Strengths
- • Hourly price monitoring (most frequent of any tracker)
- • Alerts include exact price drop amount, airline, flight number
- • Track specific flights, not just routes
- • Custom alert thresholds (e.g., only drops >$20)
- • Per-flight price history charts
- • Works in browser — no app needed
Weaknesses
- • No flexible date search or explore map
- • Hourly monitoring requires Pro ($6.99/mo)
- • Newer platform, smaller brand recognition
- • No in-app booking — links to airline sites
Best for: Travelers who've already found the flights they want and need a dedicated tracker to monitor prices and alert them on drops.
Google Flights — Best Free All-Around Option
Google Flights is the best free tool for finding flights — the date grid, Explore map, and flexible date search are genuinely excellent. It also has a basic "Track prices" toggle. However, the tracking is limited: it checks once per day, sends vague alerts ("prices are low"), and tracks routes, not specific flights.
Strengths
- • Completely free — no paid tier needed
- • Best flexible date and destination exploration
- • Broad airline and route coverage
- • Date grid shows cheapest days at a glance
- • Clean, fast interface
Weaknesses
- • Checks prices only ~once per day
- • Alerts are vague ("prices are low" — no specifics)
- • Cannot track specific flights or flight numbers
- • No custom alert thresholds
- • No roundtrip pair tracking
Best for: Initial flight research and casual tracking. Pair with a dedicated tracker for serious monitoring. See our full comparison.
Hopper — Best Mobile App with Buy/Wait Predictions
Hopper is a mobile-only app that combines price tracking with buy/wait predictions. Its signature feature tells you whether to book now or wait for a better price based on historical data. The app is polished, and it also offers a "Price Freeze" feature that locks in a fare for a fee.
Strengths
- • Buy/wait predictions based on historical data
- • Price Freeze feature locks in fares for a fee
- • Clean, intuitive mobile interface
- • Push notifications for price changes
- • Price history charts
Weaknesses
- • App-only — no web version
- • Checks prices roughly once per day
- • Monetizes through in-app bookings (bias concern)
- • Cannot track specific flight numbers
- • Limited airline coverage on some routes
Best for: Mobile-first travelers who want buy/wait guidance and don't mind booking through the app. See our full comparison.
Kayak — Best Metasearch with Basic Alerts
Kayak is primarily a metasearch engine — it compares prices across airlines and OTAs. It also offers basic price alerts via email. Kayak is not a dedicated tracker, but its alert feature is serviceable for travelers who already use it for search.
Strengths
- • Free price alerts with no account needed
- • Strong metasearch across airlines and OTAs
- • Explore tool for flexible destinations
- • Hacker fares (mixed-airline combos)
Weaknesses
- • Alerts are basic — limited detail on price changes
- • No per-flight tracking or price history
- • Checks prices roughly once per day
- • No custom alert thresholds
- • Ad-heavy results can be confusing
Best for: Travelers who already use Kayak for search and want basic alerts without switching tools. See our full comparison.
Skyscanner — Best for Budget Travelers
Skyscanner aggregates fares from the widest range of sources — including smaller OTAs and budget carriers that other tools miss. Its "Everywhere" search is great for flexible travelers. Price alerts are available but basic.
Strengths
- • Widest coverage of OTAs and budget airlines
- • "Everywhere" search for flexible travelers
- • Entire month view for cheapest days
- • Completely free
Weaknesses
- • Price alerts are basic and infrequent
- • No specific flight tracking
- • No price history charts
- • Redirects to third-party sites for booking
Best for: Flexible travelers looking for the absolute cheapest option across the widest range of providers.
Airfarewatchdog — Best for Curated Deal Alerts
Airfarewatchdog takes a different approach — instead of tracking specific flights you pick, it uses a combination of algorithms and human editors to find deals and push them to you. You set your home airport and get emailed when unusually good fares appear.
Strengths
- • Human-verified deal alerts
- • Finds deals you wouldn't search for
- • Simple setup — just set your airport
- • Good for discovering new destinations
Weaknesses
- • Cannot track specific flights or routes
- • Alerts are editorial, not real-time
- • No price history or charts
- • Deals may not match your travel dates
Best for: Flexible travelers who want to discover deals without doing the searching themselves.
AwardFares — Best for Points and Miles Travelers
AwardFares is a niche tool for frequent flyers who book using points and miles. It tracks award seat availability across loyalty programs and alerts you when desired seats open up. Not a traditional price tracker, but extremely useful for its target audience.
Strengths
- • Tracks award seat availability across programs
- • Multiple checks per day
- • Custom alerts for specific routes and classes
- • Availability calendar view
Weaknesses
- • Only useful for award/points bookings
- • Paid tiers required for full features
- • Steeper learning curve
- • Not for cash fare tracking
Best for: Frequent flyers who book with points/miles and want to track award seat availability.
How to Pick the Right Tracker
The best choice depends on where you are in the booking process:
Still exploring dates and destinations?
Start with Google Flights or Skyscanner. Their flexible search tools help you figure out where and when to fly.
Found your flights, waiting for a better price?
Switch to Trip Manta. Its hourly monitoring and specific flight tracking are designed exactly for this stage — it'll catch price drops other trackers miss.
Want someone to tell you "buy now" or "wait"?
Try Hopper. Its prediction model is helpful if you trust algorithmic recommendations and prefer a mobile-first experience.
Flexible on dates, just want the cheapest fare?
Set up alerts on Airfarewatchdog or use Skyscanner's "Everywhere" search to find deals you wouldn't think to search for.
Our Recommended Workflow
Based on testing all seven trackers, the most effective approach for most travelers combines two tools:
Search with Google Flights
Use the date grid, Explore map, and filters to find the best routes, dates, and flight options.
Track with Trip Manta
Once you've found 2-3 flights you'd book, add them to Trip Manta for hourly monitoring. You'll get an instant email the moment a price drops.
This combination gives you the best of both worlds: Google's unmatched search tools plus Trip Manta's dedicated tracking. The free tiers of both are sufficient for most trips.
