We all found ourselves confronted with a search for repetitive and exhausting low cost flights, all to find the best deals and save as much as possible. Here are 6 useful tips to keep in mind so as not to stress too much. 1. Keep your Top Secret search If you think the price of a flight changes often after searching it several times you are not crazy and your computer is not broken. In fact, the airlines change the prices of low cost flights based on your browser's cookies , when they realize that you are looking for them repeatedly, in such a way as to scare you and make you book as soon as possible. For this the best thing to do is to always search for flights in incognito mode , here's how: on Google Chrome or Safari , press Command (or "Control" if you use a PC) + Shift + "N". On Firefox or Internet Explorer , press Command (or "Control" if you use a PC) + Shift + "P". This command will open a new browser window in which cookies can not be traced by the various sites you visit. Screen-Shot-at-10/11/2014 3:35:57-pm-1024x284 2. Use the best search engines for low cost flights All search engines for low cost flights impose their own fare on the real ticket price in exchange for the service they offer, some (such as Expedia) are much more expensive than others, here is a list of what we consider the best: Skyscanner (our first choice) Edreams TripAdvisor Google Flights Azair (Europe & Middle East) No search engine for low cost flights is perfect (although Skyscanner is certainly a great service) so we suggest you try more than one to compare the various offers, also because there does not seem to be one with the best prices 100% of the times. 3. Find the cheapest day to travel Although there are many theories that Tuesday is the best day to book low-cost flights and save money, the truth is that there is no certain day of the week when flights are cheaper. The best strategy is to have an immediate graphical representation of the whole month , to understand what is the day when it is cheaper to book. Here's how: Step 1. Go to SkyScanner Step 2 . Enter the city of departure and destination Step 3 . Choose "one way" (even if you need the return, you understand first on what day you should start) Step 4 . Instead of selecting a date, choose "All month" Step 5 . Click "Search" graph Repeat these steps for the return flight. 4. Befriend the low cost airlines Low cost airlines offer much lower prices than others, but of course this provides for small sacrifices during the trip (no food and drinks for free, less space for the legs and to sit ...). Here are a couple of useful tips always valid for those who choose to travel by saving on the flight: - Check where the airports are located (many low cost airlines fly from the secondary ones) - Make sure that the baglio you are carrying fits the company's standards, the cost for those who break this rule is always very salty ... - Read the clauses.
