Frequently Asked Questions
When is the best time to book flights?
For domestic flights, booking 1-3 months in advance typically yields the best prices. International flights are best booked 2-8 months ahead. Tuesday and Wednesday departures tend to be cheapest. Google Flights and Hopper both offer price prediction tools that tell you whether to book now or wait.
How do I find the best travel deals?
Start with Google Flights for the broadest search, then cross-reference on Kayak and Skyscanner. Set up price alerts on all three — they'll email you when prices drop. Use flexible date searches to find the cheapest days to fly. Booking directly with airlines sometimes offers better cancellation policies than third-party sites.
Are there hidden fees on booking sites?
Google Flights, Kayak, and Skyscanner are meta-search engines that redirect you to airlines or hotels — they don't charge fees themselves. Booking.com includes all taxes upfront in most regions. Hopper charges service fees on some bookings but offers price freeze and cancellation protection in return.
Do loyalty programs work with booking sites?
If you book through Google Flights or Skyscanner and get redirected to the airline directly, your loyalty points apply normally. Booking.com has its own Genius loyalty program with discounts. Kayak doesn't affect loyalty programs since it redirects to the provider. For maximum points, book directly with airlines when the price difference is small.
