Hopper

Hopper is a mobile-first travel booking app built around price prediction, telling users whether to book a flight or hotel now or wait, based on its analysis of historical pricing. Users can watch routes and get notifications when prices change, and the app sells flights, hotels, homes and car rentals. Hopper also offers paid add-on protections, such as the option to freeze a price for a set period or to secure more flexible changes or cancellation, which suit travellers with uncertain plans. These add-ons cost extra and come with their own conditions, so their value depends on how likely you are to use them. Predictions are estimates and cannot guarantee a lower fare. Before booking, compare the total price including any add-ons with the airline's or hotel's own site, and read how support and refunds work if something goes wrong.
