&gt; Rates are not raised because you&#x27;ve been browsing them for awhile<p>That&#x27;s <i>exactly</i> what they do. If you&#x27;re browsing for plane tickets and you&#x27;re a bit undecisive (like me), don&#x27;t be surprised if the prices go up by 200% for that specific day you wanted to book. Going incognito and in some cases returning after a hour will bring the prices back down.
