Frequently Asked Questions
5 questions
Skyscanner typically finds cheaper flights because it indexes 1,200+ airlines including ultra-low-cost carriers like Ryanair, AirAsia, and Spirit that Kayak may miss. On routes with budget carriers, Skyscanner found prices 8-15% lower in 2025 studies. However, both are metasearch engines that redirect to booking sites, so the final price depends on direct airline pricing that day.
