Here’s a pro tip for your flight booking: clear you internet cache.
When you visit any kind of booking site, or airline website- they cookie you for third party advertising and other such big-data/big-brother things.
However, they mainly cookie you so they can spot the trend in what you’re searching. If you don’t clear your cache, that booking site will notice your return and- I kid you not- raise the prices.
It’s a scare tactic to make you buy now. Holy cow! The price has gone up already! I better buy this ticket right away!!!
Nope. They’re just messing with you. Clear your cache and try again.
Note: your cache is not the same as your history. Here’s a Wikihow on how to clear your cache.
