How does Airfarewatchdog find such amazing flight deals daily?

We are a group of people really passionate about flight deals. Every day, we track thousands of flight routes and pick out only the best deals we can find. We consider things like number of stops, total flight time, travel dates, and maximizing time at each destination. We also track prices over time, letting you know when fares drop or are expected to rise allowing you to feel confident in booking your flight. Plus, we also watch for unadvertised deals, promo code sales, and mistake pricing (it can happen!).

Why should I sign up for Airfarewatchdog?

Flight prices are always changing; instead of spending all day searching for flight deals, we’ll do the work and alert you when the deals happen. We’ll share money-saving tips, industry news (like new routes from your home city) and airline flash sales.

How do I get alerted when you find great flight deals?

<a href="/fare-alerts/" target="_blank">Sign up for alerts</a> on as many routes as you want, and we’ll send you an email when prices are low. You can also get inspired by <a href="/fare-alerts/" target="_blank">signing up for Departure Alerts</a> for cheap fares to popular destinations from your home airport.

Does Airfarewatchdog have deals from all airlines?

Yes! We track prices across all airlines, even the ones that don’t advertise on traditional booking sites (like Southwest).

Can I book flights on Airfarewatchdog?

No, Airfarewatchdog is not a booking website. We report on the flight deals we find each day, including the price we found, the dates of travel, and other important information to help you find the fare. We then provide links to popular booking sites where you can ultimately book your travel.

How is Airfarewatchdog different from other flight comparison websites?

We have years of industry knowledge and know a good deal when we see it. Unlike Online Travel Agencies that show every flight, we do the analysis for you and surface only the best prices. We will also track prices over time on your favorite routes, or inspire trips you might not have considered. Of course, if you have exact dates for your trip, we also offer a comparison tool to allow you to search current prices across our partners’ sites.
