Yes, many travel agency platforms can track price changes for flights your customers are watching and notify you when prices fall, though the details depend on which suppliers you work with and what your software plan includes. The way this usually works is that you or your customers mark certain routes as ones to monitor, and the system checks those prices on a regular schedule. When the price drops below a certain level or changes significantly, you get an alert so you can reach out to your customer and let them know it might be a good time to book.
Keep in mind that how often prices are checked and how quickly you get notified can vary. Some suppliers update their prices constantly throughout the day, while others update less frequently. Your software plan will determine whether you can set price alerts for unlimited routes or if there are limits on how many you can watch at once. You should also understand that a price drop alert is just a heads up, not a guarantee that the price will stay low or that the flight will still be available when your customer decides to buy.
The best next step is to check with your software provider about what price tracking features are included in your plan and which suppliers those alerts work with. Ask specifically whether you can set custom price thresholds so you only get alerts when prices drop by an amount that matters to your business, and whether your customers can set up their own alerts through your portal or if you have to do it manually for them.
