It might surprise you to know that airlines update their airfares about 250,000 times a day.
It’s a system driven by algorithms that then have to adjust to movements in supply and demand. And this also applies to hotel rates.
So any time you make a reservation and then book a flight or hotel room, set some price alerts.
Expedia, Google and Kayak are a few of the sites that have price tracking ability that give you the tools to monitor those fluctuations.
And if the fares or room rates drop, you get alerts that allow you to possibly rebook at a lower fare.
Are you renting a car? Slash is a site that performs the same service that tracks your reservation and monitors price drops.
