Finding Cheap International Flights

Use Google Flights to track routes and set price alerts at least three months in advance. Book when the price drops to the lower end of the historical range, and always be flexible with your departure dates by checking the calendar view.

  1. Set up a Google Flights alert. Go to Google Flights, enter your origin and destination, and toggle the 'Track prices' button. This will email you whenever the fare drops significantly, saving you from manual daily checks.
  2. Use the calendar view. Before locking in dates, click the date field to open the calendar. It shows prices for every day of the month; moving your trip by just two days can often save you $200 or more.
  3. Check nearby airports. When searching, add up to five origin and five destination airports. Flying into a secondary airport like London Gatwick instead of Heathrow, or driving 90 minutes to a larger hub, frequently uncovers cheaper inventory.
  4. Book at the 'Sweet Spot'. For international flights, aim to book between 3 and 6 months before your departure. Prices rarely drop lower than their baseline if you wait until the final 21 days.
Should I use an incognito window?
No. Modern airline dynamic pricing is based on supply and demand, not your browser cookies. Tracking sites and alerts are far more effective.
Is it cheaper to book on a Tuesday?
No. That is an old myth. Prices change based on inventory and load factors, not the day of the week you purchase.
What is the best way to book: airline direct or third-party?
Always book directly with the airline. If there is a cancellation or delay, dealing with a third-party site's customer service is significantly harder and slower.
