When we go into the net and begin the process of looking for the most economic flights, there are many possibilities that can be discussed about the period of time when you should travel, many things about strategies on including a weekend always in between in order to reduce the price of the flight, and of course always look to avoid the big holidays.
Nothing new for anybody I imagine, as we can find this information everywhere in every single article. The really interesting thing is to know a couple of data that can help you get some advantage in your flights compared to the others. The idea is that the persons who reads this article will be able to get cheapest flights than the ones who don't. Let's take a look at the two examples. The first is improbable. The second will always work.
The first thing then is to consider the following: search engines are not perfect and they do have failures. Theses failures can be on the side where the customer is not benefited directly or even can make the conditions worse, as a mistake where a flight is overpriced, or on the side of a benefit, where the price of the flight for a strange reason appears reduced. (missing numbers, wrong numbers...)
Performing thousands of operations a day, it comes a time when these engines fail, and when they fail you can take the opportunity. Having some contacts in the travel world I know that in a single travel agency an average of 3 failures will happen every month. If you multiply this by the number of search engines, airline engines, hotel booking engines and so on, you can understand that even being not probable there is the chance that it happens.
But we are not going to wait for that chance, because somebody has already studied at which time this things are used to happen. In local time of the place where the headquarter for the search engine's company is based, the backup of the system is done normally between 2:00am and 4:00am, which is the time when less searches are expected. During backup of the system is when the number of errors drastically increases. Even if from a point of view of sleeping it's really killing if you are based in the same place as the company, there is always the chance that some numbers go wrong.
Still, the opportunity is minimum, and for the people like me that prefer to keep it simple and most probable, there is another way that even if it can provide with not such great discounts (like losing one of the numbers of the price, in the example before), it certainly always happens.
The best day to book during the week is on Wednesdays, just around 12:30am. And the question is why? Well, statistically it happens that prices change at this time. If the company has decided to set a reduction of price for the first 100 bookings, this will be the moment when the offer will appear. Stay there, and keep refreshing the page you are interested in. Not always, but if it happens, this will be the time and day when it will.
