How can I get the same rate for travel when searching online?

Sandy hears that airlines can raise the price of a ticket if she doesn't buy it right away. Leo says that's true. Browsing an airline will put a "cookie" in the browser which will save the information and the site will then see she's been there and raise the cost. Leo recommends clearing her cookies, or better yet, browse in incognito or private mode. That way she's always looking with "fresh eyes" and they don't know who she is until she's ready to check out.
