What is a flight price tracker?
A flight price tracker is an airfare monitoring tool that rechecks a saved route or itinerary and records how its fare changes. Trip Manta watches the specific flight you choose 24/7, keeps its observed price history, and emails you after a decrease meets your alert threshold.
It works as a web app that tracks flight prices, so there is nothing to download. You can create and review trackers from a phone or computer while keeping broad flight research in the search tool you already prefer.
Based on more than 1.4 million flight price checks
TripManta Pro found 76% more price drops than daily checks.
TripManta Pro checks every hour, 24/7. Checking once a day found only 57% of the price drops that hourly tracking found.
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 can act while the lower fare is still available instead of relying on another manual search.
