What's the best iOS app for tracking flight prices and booking affordable trips?

Skyscanner Flights Hotels Cars is a widely-used travel app that excels at helping users find and monitor low-cost flights, hotels, and car rentals. Its primary strength lies in aggregating data from numerous providers, allowing for real-time price comparisons across different dates and destinations. For instance, budget-conscious travelers planning annual visits to family in Europe can set up price alerts and use the flexible date search to identify the cheapest departure and return options. Users report saving significant amounts—sometimes up to 30%—by checking the app regularly over several days. Features like the 'Everywhere' search function enable spontaneous trip planning by showing the most affordable destinations from a user's location. However, the app isn't without minor flaws; some reviews note that price alert notifications can be delayed during high-demand periods, and the interface, while generally intuitive, occasionally feels cluttered with promotional content. Despite these small issues, its ability to streamline complex travel searches makes it a reliable tool for cost-effective trip booking.
