We’ve all experienced the frustration of seeing a flight priced at $600 one day, only to watch it jump to $900 less than 24 hours later.
“But I did everything, right!” you tell yourself.
You booked at least nine months before your departure date on a Tuesday. You even went the extra mile by searching in incognito mode and using a VPN for added security.
