Currently, there is great competition between flight search engines and airlines which benefits us a lot since we can buy the same flight in different ways and through different platforms, so if we carry out a proper search, we can find it at the best price.

We tell you which are the 4 most useful flight search engines:

1. Skyscanner: this is definitely one of the best. The search engine offers you endless possibilities and filters to choose from so that your search is as precise as possible. To find out the cheapest time and destination, you can select the “cheapest month” option and you can also search for flights from your airport to a country without selecting the city, so you can see which city is cheapest to travel to. In addition, you can select whether you want the flights to be direct or not since flights with stopovers at other airports are usually cheaper. You can even create price alerts to receive information by mail and the database is very extensive, so you will have hundreds of options to choose from.
2. Gotogate: this search engine is practically the opposite of the previous one. It is very basic and straightforward and offers fewer filters and fewer flights than other search engines. However, it has very good offers. If you are lucky and check it frequently, you will be able to find the cheapest flights.
3. Momondo: in this search engine, you will be able to select the most popular cities and countries very quickly. It has a very simple design and with the "flight forecast" function, it will help you know when to book, what day to fly, and even which is the cheapest airport. As in Skyscanner, a price calendar is shown in the results, which is very useful if you do not have to travel on a specific date to know when is the best time to make the trip.
4. Kayak: with this flight search engine, you will have guaranteed results since it works with hundreds of websites and search engines to get the best price. You can also create alerts to let you know when a trip you're interested in drops in price. Another feature of this website is that it makes a price prediction for the whole month, and warns you if the price of the ticket could go down a lot at some point in the near future.

One of the biggest expenses when you decide to live in Spain can be the plane ticket, especially if you live particularly far away or if you wait until the last minute to buy it. It is very important that you find the right page to buy your flight since on some pages the same flight can raise the price much more than on others, mainly on the official pages of each airline.

The price of the same flight can vary depending on which page you look for it or what day and at what time of day. If you don't know where to look, you can find out here, but another important factor to save when buying your flight is the time you buy it. You can save up to 20% depending on the day of the week you buy it, and even 50% depending on the month in which you make the payment.

• Month: the perfect month to buy your plane tickets will logically depend on the month in which you are going to travel. In general, the cheapest months to travel are January, February, and September. Therefore, you are in luck, since these are the months in which the academic year usually starts, while June and July are the most expensive. It also depends on the type of flight; if it is a short-haul flight, the best time to buy it is about 2 months before the date, while if it is a long-haul, they recommend buying it between 2 and 8 months in advance.
• Day: the day of the week you buy the tickets can also affect the price. According to a study by the Wall Street Journal, the time when we are most prone to buy a ticket is when the price rises the most. Weekends are the worst day to buy them as everyone has more free time. In addition, many offers go out on Mondays, and throughout the week the airline increases the price based on your demand. Therefore, the best days are usually Monday or Tuesday.
• Time: following the theory that the price of a flight depends on people's willingness to buy it, the worst time to book a flight is at night. On the other hand, the best time to buy it is lunchtime, that is, around 3 in the afternoon, since everyone is eating or working, and there will be hardly any demand at that time.

Also, you can use the “price alert” option. Some search engines offer you this option and, if a specific flight that interests you drops in price, the website sends you an email to let you know, but you will have to be attentive and pay for it immediately before the offer expires. Another very useful trick is to search for flights in an incognito tab. Otherwise, your search engine will remember the search you have done and when you do it again in the future it will probably increase the price.
