  • International Flights: Start searching tickets in the summer months, usually 2-8 months before you have to fly.
  • Tracking Tools: Use Google Flights to set price alerts for your specific holiday dates so you are notified when fares drop.

Tips to Save on Christmas Travel

  • Fly on the Holiday: Flying on Christmas Eve or Christmas Day itself is cheaper than traveling the days immediately before. 
  • Choose Cheaper Days: Mid-week flights (Tuesdays and Wednesdays) or Saturdays tend to have lower fares than peak travel days like the Friday or Sunday right before Christmas. 
  • Consider Alternative Airports: Check secondary or regional airports near your destination to cut total ticket costs.

  • Standard Travel: Book between 1 and 3 months ahead. Prices usually spike sharply during the final 3 weeks before a flight.

The best time to book international flights is generally 2 to 8 months in advance, with a prime sweet spot falling around 3 to 6 months before departure.

  • Too Early or Too Late: Booking more than 6 to 11 months out can mean paying inflated introductory rates, while booking within 3 weeks of departure usually triggers last-minute price spikes.

Efficient Tips to Save Money on Flying

Follow the tips after knowing when is the best time to buy plane tickets:-

  • Use platforms like Google Flights or Going to track price changes for your specific route automatically.
