When should I buy my plane tickets?

The best time to buy a plane ticket at the lowest price is generally Tuesday or Wednesday, between midnight and 6 a.m. This is when airlines adjust their fares after the weekend, taking advantage of lower competition.

Summary: when to buy your plane tickets?

• Domestic flights: ideally buy 25 to 90 days before departure (often 1 to 3 months), with a savings peak mentioned around 25 days.
• Short-haul European flights: book 28 to 60 days in advance (optimal zone cited as 50 to 60 days, or about 1 to 2 months).
• International and long-haul flights: aim for 3 to 6 months in advance (and up to 8 to 9 months in high season, for Christmas or the Overseas Territories).
• Day and time of purchase: prioritize purchasing on Sunday (up to 17% on certain international flights) or Tuesday/Wednesday (about 5 to 6%), ideally between midnight and 6 a.m.

When to buy a plane ticket to pay less

To pay the best price for your plane ticket, it is best to book your ticket in advance, ideally on a Sunday, Tuesday, or Wednesday. On those days, between midnight and 6 a.m., airlines adjust their rates after analyzing demand. You could benefit from average drops ranging from 5 to 17% compared to Fridays or weekends. These are also key tips for finding cheaper plane tickets.

Here is the ideal timing to remember:

• Anticipate 1 to 3 months for domestic flights.
• Prepare your booking 3 to 6 months in advance for international flights.
• Choose a departure on Tuesday, Wednesday, or Thursday and a return on Wednesday. This strategy can generate savings of up to €150 per trip due to lower demand.

These recommendations are based on reliable data: average prices drop significantly in the middle of the week. You can find these advantageous rates on platforms like Kayak or Google Flights.

Is there really a best time to buy a plane ticket

No, there is no universal moment to buy a plane ticket. Ticket prices vary based on the destination, the season, the demand, and local events. Thus, any ideal timing is contextual and not fixed. For example, prices tend to drop in January (-11.3% compared to the average) or in March, but rise sharply in August (+25%), July (+20%), and December (+17%), regardless of the departure date.

Demand is the key factor: it is high during vacation periods, which drives up fares, while off-peak periods often offer more attractive rates.

Myths and realities about purchase timing

The myth that Tuesday is the cheapest day to buy a plane ticket is partially true. Some studies show a 5 to 6% price drop on that day. However, Sunday often proves more advantageous, with savings reaching up to 17% on international flights. This is explained by airline fare updates after the weekend.

Buying a ticket at night (between midnight and 6 a.m.) can also be beneficial, as competition is lower, thus reducing price volatility. However, this is not a magic solution, as everything depends on the airlines' algorithms.

Contrary to popular belief, private browsing does not have an impact on prices. Prices are adjusted based on collective IPs and shared cookies, not individually. Although incognito mode prevents cookies from being saved, it does not protect against overall fare increases.

Finally, booking too far in advance (more than 6 months) can cost up to 15% more on average. Flight prices tend to decrease between 21 and 56 days before departure, a period often considered optimal.

How plane ticket prices work

Plane ticket prices are based on yield management. Airlines use sophisticated algorithms to adjust fare classes in real time, based on supply and demand. If a flight is not filling up, rates shift to low-cost classes. Conversely, if demand is high, prices increase significantly in the final weeks, with hikes of 20 to 30%.

Events like holidays or tourist peaks accentuate this volatility. Prices can fluctuate significantly about 30 days before departure. At that point, the risk of an increase is maximal, but it is sometimes possible to find lower average prices.

How long in advance to buy your plane ticket

The ideal time to buy a plane ticket depends on the type of flight. Here are the optimal windows for saving:

• European short-hauls: 28 to 60 days before departure.
• Domestic flights: 25 to 90 days before, with a savings peak at 25 days.
• Long-hauls: 3 to 6 months before, or even 9 months for high-traffic periods.

Note: buying a ticket more than 106 days in advance can increase the risk of paying more.

Type of flight	Optimal window (days/months)	Average savings
Short-haul Europe	50-60 days (1-2 months)	15-20%
Domestic	25-90 days (1-3 months)	33% at 25 days
International	30-37 days to 3-6 months	24% on Sundays
Long-haul	4-7 months (9 in high season)	Optimal at 42 days

Short-haul flights

For short-haul flights (less than 6 hours), book between 1 and 3 months before. The best time is between 50 and 60 days, a period when low-cost companies like Ryanair often offer attractive rates. In contrast, regular airlines keep prices stable for longer.

Example: a Paris-London flight costs an average of €143 if booked 30 days in advance, but prices rise sharply as departure approaches.

Long-haul flights

For long trips, plan between 3 and 6 months ahead, and up to 8-9 months for busy periods like Christmas or summer. Prices often drop between 120 and 180 days before departure before rising again. Studies show that rates are optimal between 4 and 7 months for these flights. For a distant and expensive destination like a ticket to Tahiti, planning is doubly important: between a booking at six months and one at six weeks, the difference amounts to hundreds of euros.

For example, a long-haul flight can cost an average of €579 for a Thursday departure, when booked during the ideal window.

International vs. domestic flights

Domestic flights offer greater flexibility: book between 1 and 3 months before, with discounts reaching up to 33% at 25 days. Conversely, for international flights, it is recommended to book between 3 and 6 months. Wondering when to book a cheap flight may seem complicated, but respecting these booking windows increases your chances of saving while avoiding extra costs due to increased demand.

Tip: For domestic flights, use price alerts on platforms like Kayak to take advantage of last-minute drops. For international flights, book early, especially for popular destinations.

What is the best day and time to buy a plane ticket

Choosing the best day and best time to buy a plane ticket does not guarantee spectacular savings, but it can increase your chances of finding an advantageous rate. To do this, favor purchases in the middle of the week (Tuesday, Wednesday, or Sunday depending on the studies) and carry out your searches during off-peak hours, ideally between midnight and 6 a.m. These moments are favorable because fare updates and competition are often more favorable then.

Best days of the week

Analyses agree on a simple rule: avoid the weekend. Fridays, Saturdays, and Sundays are often more expensive due to leisure-related traffic. Instead, favor the middle of the week: several sources recommend Tuesday and Wednesday as favorable days. However, some studies and comparators indicate that Sunday can also be advantageous, especially for certain international routes.

In practice, the price difference between days can vary according to the period and destination. Sometimes, significant gaps (up to 15 to 25%) are observed, while other analyses note more modest variations of only a few percent. This is why it is essential to remain flexible on dates and use comparators to spot fare fluctuations.

Hours to favor or avoid

Off-peak hours, especially between midnight and 6 a.m., are often cited as favorable. During this time window, fewer Internet users make bookings, and airlines frequently publish or adjust their fare lots, which can offer interesting opportunities.

However, this is not an absolute rule. Yield management algorithms update prices continuously, and targeted promotions can appear at any time of the day. The essential thing is to set up price alerts (via tools like Google Flights or Kayak) and check regularly, rather than relying solely on a "magic" hour.

When to buy according to the destination

Adapt your plane ticket booking to geography: in Europe, 50 to 60 days is enough to obtain competitive prices. In the United States, allow 4 to 6 months due to strong seasonality. In Asia, anticipate between 5 and 8 months for overcrowded hubs. Finally, for the Overseas Territories, book between 6 and 9 months in advance because of limited capacity and tourist peaks.

Europe

For Europe, average lead times are 3 to 8 weeks (with 50 to 60 days as the optimal period). Low-cost airlines often offer aggressive deals, unlike regular airlines that remain more stable. This favors attractive rates on routes like Paris-Rome or London-Barcelona. Favor direct flights to avoid unnecessary stopovers. On a seasonal link like a flight to the Azores, plan further ahead: in July and August, everything must be booked several months in advance.

United States

For the United States, it is recommended to anticipate your booking 4 to 6 months in advance due to marked seasonality, especially summer and Christmas peaks. For example, a flight to New York can cost between €500 and €700 in the ideal window, compared to doubled rates at the last minute.

Asia

In Asia, an advance booking of 5 to 8 months is advised, especially for destinations like Tokyo or Bangkok. These hubs are often overloaded due to major events such as festivals or national holidays, as well as transpacific influxes that quickly drive up flight prices.

Overseas Territories

For the Overseas Territories, it is important to book very early, between 6 and 9 months before your departure. This anticipation is necessary due to strong seasonality (like winter for the Caribbean or summer for the Indian Ocean) and capacity constraints on limited flights, for example between Paris and Martinique.

When to buy according to the season

The season plays a determining role in choosing the best moment to buy your tickets. During high season and school holidays, it is essential to anticipate your bookings as early as possible. In contrast, in low season, you will benefit from greater flexibility and have the opportunity to find good last-minute deals, thanks to generally lower demand.

School holidays

During school holiday periods, book your tickets as soon as sales open. Reduced-rate seats fill up quickly, and waiting until the last minute can be expensive and risky. Indeed, some routes see their prices doubled or tripled as departures approach during these periods.

High season

In high season (summer, Christmas, local holidays), it is essential to plan your purchases well in advance. Airlines limit capacity, and economy fare classes are often sold out quickly. Remember to lock in your tickets several months before the scheduled date. To reduce costs, consider alternative airports or different dates. For a flight to Muscat, this applies to departures from December to February, the Omani high season, when hotels and desert camps are also booked in advance.

Low season

The low season offers more flexibility. You can wait for interesting promotions or try last-minute offers. However, it is advisable to activate price alerts and remain flexible regarding dates and airports. Comparators and alert tools are particularly useful for spotting these opportunities and maximizing your savings.

Tips for paying less for your plane ticket

Discover how to achieve significant savings on your plane tickets thanks to practical advice. Activate price alerts, explore different comparison platforms, and adopt maximum flexibility for your dates and airports to take advantage of discounts of up to 50%.

Use price alerts

Price alerts are a valuable tool for monitoring fare fluctuations. They notify you as soon as a price drops, via email or app. Activate them on platforms like Kayak, Skyscanner, or Google Flights as soon as you start planning your trip. To maximize your chances, choose flexible date windows (±3 days). This allows you to spot opportunities for discounted tickets without having to check constantly.

Compare on multiple engines

Do not limit yourself to classic flight comparators like Kayak or Skyscanner. Also check the websites of airlines, online agencies, and tour operators. The latter sometimes negotiate blocks of seats at very competitive prices. By diversifying your searches, you avoid the biases of search engines that favor certain partners.

Be flexible with dates and airports

Flexibility is key to saving on your plane tickets. By adjusting your travel dates by +/-3 days or opting for secondary airports (for example, Beauvais instead of CDG, or Mexico City before Cancun), you can significantly reduce your costs. Use Google Flights’ monthly calendars to visualize the lowest fares and consider hybrid routes by combining low-cost flights for an ultra-economical solution.

Errors to avoid when buying a plane ticket

To secure your purchase of plane tickets, it is essential to avoid certain classic traps that can inflate the final price. Pay attention to timing, check the included options, and track the ancillary fees that can sometimes double the bill.

Buying too early or too late

Booking too early can expose you to high fares before algorithmic adjustments kick in. Conversely, waiting until the last minute increases the risks of overbidding or unavailability. It is important to book within optimal windows to avoid regretting a hasty decision.

Not checking included options

Not checking inclusions, such as baggage, assigned seats, or modification conditions, can lead to unexpected fees at the airport. Take the time to read the details carefully before finalizing your payment, especially for basic economy tickets, which are often subject to strict restrictions.

Ignoring ancillary fees

Fees related to payment, checked baggage, seat selection, or insurance often add up discreetly and can significantly increase the bill. Compare platforms for their transparency and use payment cards without extra charges to preserve your savings.

FAQ: when to buy a plane ticket?

Should you buy your ticket at night
