Here’s a practical list of places people commonly use to find cheap flights: Skyscanner, Google Flights, KAYAK, momondo, Expedia, Trip.com, Booking.com, and Going. These services compare fares across airlines and online travel agencies, and several explicitly highlight flexible-date or “anywhere” searches to surface lower prices.

Best places to start

  • Google Flights is great for fast comparison and flexible destination searches, including “Anywhere”.
  • Skyscanner is useful for broad fare comparisons across many providers.
  • KAYAK and momondo both compare prices across many airlines and travel sites.
  • Expedia , Trip.com , and Booking.com can be helpful when you want to compare and book in one place.
  • Going focuses on flight deal alerts and can be useful if you want mistake fares or flash-sale style alerts.

How to get cheaper fares

  1. Search with flexible dates.
  2. Compare nearby airports.
  3. Use “whole month” or “cheapest month” views when available.
  4. Set price alerts and wait for drops.
  5. Check more than one site before booking. These tactics are consistent with the flexibility advice shown by the flight sites above.
