Why does timing make all the difference?
Airfares are governed by yield management, a complex science that adjusts prices according to demand, the season, load factors and, of course, sales. As a result, booking too early or too late can mean you miss out on significant savings.
The ideal booking window depending on the length of your flight
Recent studies recommend optimal booking times before departure depending on the length of the journey:
- For flights within France: on average, the ‘magic window’ is between 1 and 3 months before departure, with the best deals typically available around 50 to 60 days beforehand.
- For short- or medium-haul flights (travel within Europe or flights of less than 6 hours): ideally 50 to 60 days before departure.
- For long-haul or intercontinental flights: the recommended window is around 3 to 6 months before departure, excluding periods of very high demand when booking around 9 months in advance is sometimes preferable (summer, school holidays, Christmas, etc.).
Booking too early does not always guarantee the best price, and waiting until the last minute often carries a risk.
Which day of the week should you buy your flight ticket?
Contrary to the ‘Tuesdays are best’ myth, the data shows that:
- Sunday is the best day to book a flight, with savings of up to 6 per cent on domestic flights and 17 per cent on international flights, compared to Fridays or Mondays. In practice, the difference between days is relatively small (around 1–2 per cent).
⏰ Extra tip: book early in the morning or at night, when booking engines are less busy; this can help you find better prices.
When in the week should you travel?
The choice of departure day also affects the price:
- For domestic flights, departures on Tuesdays or Wednesdays are on average 17 per cent cheaper than on Sundays or Mondays.
- For international flights, Tuesdays, Wednesdays and sometimes Thursdays remain the most affordable.
The general rule is: opt for midweek to travel more cheaply.
How can you put this advice into practice?
- Start keeping an eye on prices as soon as your itinerary is finalised. Use flight price comparison websites to receive alerts when fares drop.
- Be flexible: you’ll be more likely to save money!
- Book on a Sunday, Tuesday or Wednesday during off-peak hours.
- Prioritise travelling on Tuesdays, Wednesdays and sometimes Saturdays, as these are statistically often the cheapest days.
- Opt for a stopover or off-peak times to access better fares.
- Adjust your booking date according to your destination: 1 to 3 months in advance for short-haul flights and 3 to 9 months in advance for long-haul international flights.
Booking a flight is no longer just a matter of clicking at random. By following the rules of good timing, you’ll maximise your chances of getting a cheaper ticket. Now’s the time to plan smart, be a bit bold with your schedule, and finally pay a fair price for your flight. Have a great flight and enjoy the savings!
