We’ve all experienced the tiresome, repeated searching when trying to book the cheapest possible flights to any given destination. With endless search engines and continually fluctuating prices, the approach to frugal flight booking is overwhelming. Here’s some key tips that will save you time, frustration and most importantly money when booking your next flight.

1. Keep your searches top secret

You’re not crazy for thinking that a flight price has changed after searching it a few times in your web browser. Based on the cookies in your browser, flight prices do increase when a particular route is repeatedly searched, as the site wants to scare you into booking the flight quickly before prices get even higher. Always search for flights in incognito or private browsing mode to see the lowest prices.

In Google Chrome or Safari, incognito is enabled by hitting Command (or “Control” if using PC), Shift, “N”. For Mozilla Firefox or Internet Explorer, hit Command (or “Control” if using a PC), Shift, “P”. This will open a new browser window where your information is not tracked, thus not inflating prices as you search. Note: if you’re using an older version of OS X, open Safari then click “Safari” in the menu bar, and select “Private Browsing”.

Your cookies are reset each time you re-open an incognito window. So if you want to start with a clean slate for each flight search (so your previous searches aren’t “remembered”, potentially inflating costs), close all your incognito windows, open a new one, and then perform your flight search.
