Why you need a flight price tracker
Flight prices are unpredictable. Airlines adjust fares constantly based on demand, competition, and seat availability. A flight that costs $450 today might be $320 tomorrow and $500 the day after. Without a tracker, you either check manually every few hours (and still miss drops) or you guess and hope you booked at the right time.
The problem gets worse after you book. Most travelers don't know that major US airlines may offer flight-credit options when an eligible fare drops after purchase. Trip Manta price protection monitors the booked itinerary and works with the airline when a credit opportunity appears.
A flight price tracker solves both problems. Before booking, it tells you when prices dip so you can book at the right moment. After booking, price protection watches for further drops and can help with eligible airline flight credits. Travelers who use price tracking commonly save $50-200 per domestic roundtrip and even more on international flights.
How the flight price tracker works
Search for a flight
Enter your origin, destination, and travel dates. We search across all major airlines to find available flights and current prices.
Click Track to start monitoring
Select the flight you want to track and click the Track button. Trip Manta begins monitoring the price immediately — no app download needed.
Get email alerts when prices drop
When the price drops, you get an instant email with the new price and a direct booking link. No checking back, no manual comparisons.
What makes Trip Manta different
Hourly price monitoring
We check prices every hour, not once or twice a day. Short-lived price drops that other trackers miss get caught by our hourly scans.
Instant email alerts
The moment a price drop is detected, you get an email with the old price, new price, savings amount, and a direct link to book.
Free to use
Track unlimited flights with daily price checks at no cost. Upgrade to Pro for hourly monitoring at $6.99/month.
Price history charts
See how prices have changed over time for your tracked flights. Spot trends and decide the best moment to book.
All major airlines covered
Delta, United, American, Southwest, JetBlue, Alaska, Spirit, Frontier, and international carriers. If it's on Google Flights, you can track it.
Roundtrip and one-way
Track both roundtrip and one-way flights. For roundtrips, outbound and return flights are tracked independently so you catch drops on either leg.
