If you're thinking about Save as much as possible on international flightsYou'll see that it's not just about finding a "crazy deal" every now and then. These days, airlines use highly sophisticated algorithms Prices fluctuate depending on demand, dates, airports, and even how far in advance you book. The good news is that if you know how the system works, you can find ways to get around it and pay significantly less for the same seat.
In this guide you will find all the strategies used by experienced travelers To hunt for bargains on international routes: from when to buy, on what days, which airports to look at, how to use search engines, alerts, VPNs, frequent flyer programs, tickets with layovers, less conventional tricks like the hidden city or splitting journeys, and also what myths you should ignore so as not to waste time or money.
Book in advance… but wisely
One of the pillars for achieving cheap international flights It's about anticipation, but simply saying "the sooner the better" isn't enough. The data shows that buying Too early or too late can be costly.and that there is an "optimal window" depending on the type of trip and the season.
To International flights during peak season (Christmas, European summer, long weekends), booking between [dates/periods] usually works well 4 and 10 months beforeFor long-distance routes, studies point to even longer timeframes: about 18 weeks for the South Pacific, 20 for Central America, 22 for South America, 24 for Asia, and up to 26 for North America.
En low seasonWhen demand falls and supply remains the same, things change: many price analyses recommend booking between 2 and 8 months before For international flights, 1 to 3 months is usually sufficient for domestic routes. Generally, avoiding booking in the last week is key, because prices fluctuate. They spike in the 5 days prior at the exit.
There are also patterns by month of the year: January and February are usually the best months to bookWhile June and July see the highest prices due to the summer season, during autumn (September and October) it is common to find rates up to 25-30% lower which is in the middle of summer for many destinations.
Regarding the day and time of purchase, several studies agree that Sunday is usually the worst time to book, while Tuesday often appears as the cheapest day. Furthermore, buying at night can be more advantageous: clear differences have been detected between bookings made between 8:00 and 20:00 and those made in the early hours of the morning, reaching up to lowest prices around 2:00 and expensive peak times at midday.
Flexibility with dates, times and seasons
Another powerful way to save money is to be flexible with travel datesSometimes, moving the outbound or return journey by one or two days makes a difference of tens—or hundreds—of euros, especially on long-haul routes.
Travel in Work days It's usually cheaper than doing it on the weekend. Tuesdays and Wednesdays tend to be the cheapest days, followed by some Saturdays with low demand, while Fridays and Sundays have the highest prices because everyone wants to leave or return then.
The unpopular hours They also help to lower the cost. Flying in the early morning, very early in the morning, or late at night is less appealing to most passengers, which translates into lower ratesIf you don't mind getting up early or arriving at odd hours, you can snag some significant savings without changing your destination.
Something similar happens with the peak holiday datesChristmas, New Year's, Easter, long weekends, August in Europe, or major events (World Cups, festivals, trade fairs) are synonymous with high prices. If you can travel a few days before or after the critical dates, or outside the central period of the high season, the price can drop significantly.
Many search engines offer price calendars and options such as "full month" or "cheapest month", which allow View at a glance the days with the best ratesTaking advantage of these tools, instead of just looking for fixed dates, makes the difference between paying the standard price or getting a bargain.
Flight comparison tools, alerts and price prediction
Today, to find the best prices on international flights It's essential to use comparison websites and advanced search engines. Tools like Skyscanner, Google Flights, Momondo, Kayak, Kiwi.com, CheapOair, or FlightHub let you see results in seconds. fares from dozens or hundreds of airlines for multiple dates and airports.
The advantage of these comparison tools is that they teach you which days are cheapestwhich airlines are cheapest for your route and whether there are connecting flights that significantly reduce the cost compared to a direct flight. Some, like Skyscanner, let you search “from X to any place"And sort by price, perfect if you're keen to travel and have a limited budget but don't mind the specific destination."
Furthermore, it is very interesting to activate price alerts On these sites, you receive an email or app notification when the ticket you're interested in drops below a certain price or changes significantly. This way, you don't have to check every day, and you can book as soon as the price falls within your desired range.
Some apps go a step further and offer price prediction based on historical data. This is the case with Hopper or certain browser extensions focused on airfares. These tools analyze thousands of routes and tell you whether it's better to buy now or wait because, according to their models, the price is likely to drop even further.
Of course, it should be borne in mind that Cheap places are limitedOften, there are only a few seats available at the lowest fare. If the comparison site shows you a price that suits you and you see warnings like "only 4 seats left at this price," it's wise to buy without delaying the decision, because when you return, there might be nothing left in that price range and it might jump to the next, more expensive tier.
Days, times and tricks when buying the ticket
Besides advance notice and flexibility, there are certain purchasing patterns that continue to have an impact. For example, many companies launch Special weekday promotions and they adjust them according to the competition, which means that some Tuesday or Wednesday mornings there are juicy discounts that are later replicated by other airlines.
They are common Flash sales and lightning deals that last only a few hours or days. To find them, the most effective way is to subscribe to airline and travel agency newsletters and follow the companies on social media such as Twitter, Facebook, or Instagram, where they often publish promotional codes, last-minute discounts, or campaigns associated with events like Black Friday, Cyber Monday, or special travel weeks.
Another practical recommendation is Avoid shopping at middayThis is precisely when the most people are typically online and algorithms reflect high demand. As already mentioned, studies indicate that the early morning hours are the peak time for internet usage. the lowest average values on many flights, although it is not an absolute rule.
Finally, when you buy, check carefully. the terms and conditions for change and cancellation of the ticket. Sometimes a slightly more expensive fare with flexible changes can save you a fortune if you later need to change dates, compared to a super restrictive offer where any change is almost like paying for the ticket from scratch again.
Alternative airports, layovers and creative routes
A very common mistake is to limit yourself to searching only in the main airport departure and arrival airports. In many cases, using an alternative airport, both at origin and destination, reduces the total cost of the trip, even when adding the extra ground transportation.
In cities with several airports, such as New York, London or ParisIt's worth comparing what happens if you fly to a different airport than the most famous one. For example, flying to Newark instead of JFK, or to Luton or Stansted instead of Heathrow, can result in significant savings, especially with low-cost airlines.
The comparison tools allow you to select the option to search in nearby airports to your origin and destination, which opens the door to more competitive flights. In Spain, for example, it's not the same to depart from Barcelona as from Girona or Reus; and in other countries there are secondary airports that function almost as "low-cost hubs" with aggressive fares.
You can also save quite a bit by opting for flights with layovers Instead of direct flights. Nonstop journeys are more comfortable and faster, but on many international routes the surcharge for flying direct is very high. Accepting one or two layovers can significantly reduce the price, provided you plan your time carefully to avoid being overwhelmed by connections.
Another interesting possibility is to book a multi-destination or open-jaw ticketThat is, flying to one city and returning from another. This is useful for trips where you plan to travel around a country or region (for example, arriving in Tokyo and returning from Osaka), avoiding the need to return to your point of origin. Well-combined, these tickets can cost cheaper than classic round trips And, in addition, they save you time and internal journeys.
Luggage, low cost and how to avoid hidden costs
Another key area for saving money is control. additional costsEspecially if you fly with low-cost airlines. These companies usually offer very cheap base fares, but then charge for almost everything: checked baggage, seat selection, priority boarding, and even in some cases, large carry-on luggage.
To keep the price under control, it is advisable travel lightIf possible, limit yourself to carry-on luggage that strictly adheres to the permitted dimensions and weight, so you don't have to pay for checked baggage. Using luggage organizers, compression bags, and carefully planning what you pack will help you do this. avoid last-minute surcharges at the counter.
Before you buy, always check baggage policies It depends on the specific airline, because there are significant differences between them. Sometimes a flight that seems cheaper ends up being more expensive than a "traditional" competitor because you add in checked baggage, seat selection, and other extras you hadn't considered when comparing.
If you're someone who travels often, you might be interested in taking advantage of this. credit cards with travel benefitsSome include free checked baggage, priority boarding, or even access to VIP lounges. While these benefits don't reduce the ticket price itself, they are still worthwhile. They cut a significant portion of the accessory costs and greatly improve the travel experience.
And, by the way, beyond the ticket itself, you can also save money by avoiding expensive services at the airportas well as official luggage lockers. There are external luggage storage alternatives in many cities, with much more competitive prices, allowing you to leave your suitcase for a few hours without paying the inflated terminal fees.
Miles, points and loyalty card programs
One of the most powerful ways to to lower the cost of international flights In the medium and long term, it's about squeezing the frequent flyer programs and rewards credit cards. Almost all major airlines have free loyalty programs (MileagePlus, SkyMiles, AAdvantage, Avios, etc.) where you accumulate miles or points every time you fly.
Those points can be redeemed later for discounts or free ticketsCabin upgrades or extra services. Although at first it may seem like you're adding up to very little, over time, and if you concentrate your flights within the same airline alliance, you can earn rewards that drastically reduce the cost of long-haul trips.
Travel-focused credit cards add another layer: they allow you to accumulate points for almost all your purchases (not just flights) and then convert them into tickets, hotel nights, or travel money. Some even include companion tickets, very generous welcome points, or refunds on taxes and surcharges when redeeming flights with miles.
It's advisable to carefully compare the terms and conditions (annual fees, exchange rates, foreign purchase fees, etc.), but used wisely, these cards can become a key tool for Travel abroad spending much less out of your pocket.
Currency, VPN, incognito mode, and “incorrect” fees
Another set of interesting tricks has to do with where and how the airline "sees" that you are buyingSome companies allow you to change the payment currency on their official website. Sometimes, paying in the airline's local currency, or in the currency of the flight's country of origin, means save money thanks to the exchange rate since certain markets have prices adjusted to local purchasing power.
To take advantage of it, you need a card with good currency exchange conditions (without exorbitant fees) and sometimes use a VPN to simulate connecting from the country in question. Changing your virtual location with services like NordVPN, ExpressVPN, or similar can cause the system to show you Different fares for the same flight depending on the country from which you "buy".
Related to this, many people choose to search for flights in incognito mode or after deleting cookies, with the idea of avoiding price increases based on browsing history. Although nowadays the real impact of this is less than people think, it certainly doesn't hurt and can help ensure you're not seeing inflated prices due to repeated searches from the same device.
Another curious phenomenon is the incorrect ratesThat is, abnormally low prices published due to technical errors, human mistakes, or currency conversion errors. Platforms specializing in detecting these errors, such as Secret Flying or Airfarewatchdog, allow Receive alerts when a "crazy fare" appears on a certain route.
If you see a rate that is clearly below market value, the key is buy as soon as possiblebefore the airline adjusts the price. Airlines don't always honor these fares, but often they do, which can get you an international flight for a fraction of the normal price.
Hidden city flights, separate tickets, and unconventional routes
Among the most advanced—and also most delicate—fields for saving on international flights are techniques such as hidden city banknote issuance (Hidden city ticketing). This practice involves booking a flight with a layover where your actual destination is the intermediate city, not the final destination. It's cheaper to "lose" the last leg of the journey than to buy a direct flight to your destination.
For example: you want to go from Chicago to San Francisco, but you discover it's cheaper to buy a ticket to Las Vegas with a layover in San Francisco than a direct Chicago-San Francisco flight. With Hidden City, you get off in San Francisco and skip the final leg to Las Vegas. Tools like Skiplagged specialize in detecting these kinds of opportunities.
This tactic may involve savings of more than €100 per ticketBut it has risks and limitations: it's only viable if you travel with hand luggage (checked luggage will fly to the final destination), goes against the conditions of many airlines, and if it is part of a round trip itinerary, the company could cancel your remaining flights if it detects that you haven't completed a section.
Another advanced approach is to buy two separate one-way tickets Instead of a round trip with the same airline. Sometimes combining different airlines in each direction allows you to take better advantage of partial promotions and get better deals. a lower overall priceYou can also divide the route into segments (for example, a cheap ticket to a major hub and another from there to the final destination) and build a tailor-made itinerary.
This strategy requires a bit more organization and time between flights, because if you buy independent sections If you miss a connection due to a delay, airlines are not obligated to rebook you for free. Therefore, it's important to allow a good amount of time between flights and weigh the risks against the savings.
There are also unconventional alternatives such as coordinate flights with package deliveriesSome platforms connect travelers willing to carry small, approved packages in their luggage with people or companies that need that transport, offering in return very significant discounts on the ticketIt's a minority option, but for certain routes it can make all the difference.
Extra tips: groups, insurance, tourism and lesser-known places
When traveling in a group there is also room for optimize the priceMany airlines manage seats in fare "packages": when a group of cheap seats sells out, the system moves to the next price tier. This means that when searching for four seats at once, only two might remain at the lowest fare, with the rest automatically moving to the next tier.
In these cases, it may be more cost-effective. Search first for 1 or 2 passengers Check if a lower price appears than the one you get when searching for the whole group. If so, you can buy two tickets at the cheaper price and then the rest at the next fare up, instead of paying the higher price for everyone. You'll just need to coordinate seats later, but the savings can be considerable with this simple change in strategy.
El travel insurance It can also indirectly help you save money, especially if your plans are subject to change. A policy that covers cancellations or changes for certain reasons can prevent you from having to pay. astronomical last-minute rates if you need to change your flight, or lose the entire value of the non-refundable ticket.
It is also worth following the tourist offices and local boards from the countries or regions that interest you. Sometimes they launch joint campaigns with airlines to promote the destination, offering Special rates during off-season or discounts associated with local events, fairs or lesser-known festivities.
Finally, don't rule out exploring lesser-known booking sitesAlthough giants like Expedia or the usual OTAs dominate the market, there are specialized websites and regional platforms that manage special agreements with some airlines and bring them to light. offers that don't appear in the most popular search enginesHowever, before paying, carefully check the site's reputation and the terms and conditions regarding issuance, changes, and refunds.
If you combine booking well in advance, some flexibility in dates and airports, the smart use of comparison sites and alerts, taking advantage of frequent flyer programs and travel cards, along with some advanced tricks like well-chosen flights with layovers or separate tickets when convenient, it's perfectly possible travel on international flights paying between 25% and 40% less than those who book without a strategy, enjoying more destinations and more experiences without their credit card smoking.
