Prices changed for a trip I'm watching. Why didn't I receive a notification?
There are a few reasons you may not have received a notification about your trip.
- Flight prices fluctuate constantly throughout the day, so Hopper will only notify you if prices change drastically or if we think you should book. We'll also send you a warning notification if we think prices are going to start to rise. However, we may not notify you of insignificant price changes unrelated to our prediction.
- If your trip is far in the future, we may not send you too many notifications yet. Some airlines don't set their schedules until six or nine months ahead of time, and we don't want to bother you until we have better data. However, you will receive notifications when your departure date draws closer.
- If you are manually checking prices for your trip in the app, we won't tell you about a price that we know you've already seen. Our system tracks the prices you have seen so we don't send you repeat notifications or redundant information. This means that you may not be receiving notifications simply because you are manually checking on your own. It's OK to do that once in a while, but we do recommend waiting for notifications.
Hopper's prediction for my trip keeps changing. Why?
Hopper continually adjusts our predictions as we see and analyze real-time pricing trends. This means that we sometimes change our recommendations. We may tell you to buy or wait based on new information we've received, such as an airline announcing a great deal or an adjusted algorithm that indicates prices are increasing faster than expected. And that's totally normal.
Hopper’s price prediction was wrong. Why did this happen, and what can you do?
We’re right 95% of the time, and we’re pretty proud of that. However, in very rare cases, a particular flight price may not follow the historical trend we predict. At this time, we do not guarantee the prices we predict, per our Terms of Service, but our data science team is always working hard on improving those predictions to help our users get the cheapest flights!
