This is the trick that most people never think of. Most airfare tips have to do with the airline itself, and the way these fares change over time. But this trick has to do with your browser, and how it communicates with flight-booking websites. When you upload a page, the website remembers that you visited before. Many bargain-hunters believe that this awareness causes the prices to steadily climb because you have already expressed interest in a given itinerary.
Google Chrome: There are a few ways to open an Incognito browser if you’re using Google Chrome. The first is to right click on the Google Chrome icon before you launch the application. This will bring up a menu with the option, “New Incognito Window.”
The second option is easy to use if you’re already browsing in Google Chrome. Simply open a new tab, then hit (and hold) the following keys down: Control, Shift, N (Command, Shift, N for Mac users).
Firefox: In Firefox, this private browsing option isn’t called “Incognito Mode,” it’s called “Private Window.” To access this, just open a new browser and click the Settings icon in the top right-hand corner. There, you’ll see a drop-down menu that lists an option called “New Private Window.”
Safari (on desktop): When using Safari on your Mac, you can open a Private Window in the same way as Google Chrome. Just right click on the icon, and select “New Private Window.”
Safari (on mobile): On mobile, opening a Private Window is a little bit different. While in the browser, tap the Pages icon in the bottom right-hand corner. This will show you all of the windows you have open, and at the bottom of the screen, you’ll see the + sign to open another window. Tapping the + sign will open a regular browser. If you’d rather browse privately, be sure to tap “Private” right beside it.
Android: To prevent the website from recognizing your IP address, Android users can employ their “incognito mode.” To use an incognito window on your Android device, open Chrome, then click More (the three vertical dots), then hit Incognito Window. When the new window opens, you’ll see the incognito icon, which looks like a face with a fedora and glasses.
Not every device or browser has an incognito-like feature, but there’s another way to get a similar effect: Most websites recognize your returning visit because of the cookies they install on your computer. Just delete all your cookies and browsing history, and these online services won’t recognize you.
There is some debate on whether using Incognito Windows and eliminating cookies don’t have a substantial impact on airfares. Each website works differently, so it’s hard to say. But feel free to tinker with a regular window and an Incognito Window and see what happens. When it comes to travel, it isn’t the destination but the journey.
