Why flight prices change

Airfares are dynamic by design. Understanding why they move helps you book with confidence instead of chasing a price that may never come.

Airlines price by seat, not by ticket

Each flight has many fare buckets at different prices. As cheaper buckets sell out, the next available price moves up. That is why the same seat can cost different amounts on different days — and why a fare you saw yesterday may be gone today.

Demand and timing drive the swings

Prices respond to how full a flight is, how soon it departs, the day of week, the season and what competitors are charging. Peak travel periods and last-minute bookings tend to be the most expensive.

What we do — and don't — do

We do not personalize or manipulate prices based on your browsing behavior. Prices are shown clearly and may change based on real-time airline and partner availability, and each deal shows when it was last checked so you know how fresh it is.
