Flydar vs. Google Flights price alerts: what's actually different
Google Flights will email you about every price wobble on a tracked search. Flydar only pings when a fare genuinely drops. Here's the real difference, side by side.
Short answer: Google Flights tells you a price changed. Flydar tells you a price dropped enough to matter. Same category, different job.
Google’s price tracking is a genuinely useful, free tool — it’s often the first thing people reach for. But it was built to notify on movement, not to judge whether that movement is worth your attention. That distinction is the whole reason Flydar exists.
How the alert itself is different
Turn on Google Flights tracking for a route and you’ll get an email whenever the price shifts — including when it goes up. That’s not a bug; it’s the tool doing exactly what it says on the tin: reporting change. But if you get a “price increased $8” email at the same volume as a “price dropped $200” email, your inbox stops being useful. Most people either mute the alerts or start ignoring them, which defeats the point of having one.
Flydar starts from a different question: not “did the price move,” but “is this route’s current price meaningfully lower than what it normally costs.” A fare has to actually clear that bar before it reaches you. Price ticks up? You simply never hear about it.
How the two tools are set up
| Google Flights price tracking | Flydar | |
|---|---|---|
| Alert trigger | Any price move on a tracked search — including increases | Only when a fare drops meaningfully below what the route normally costs |
| What’s tracked | One specific search: a route plus fixed dates or a date-grid window | A route and a travel window, set once — nothing to rebuild after your dates pass |
| Whole-city routes | Search each airport separately | Pick a city; every airport in it is covered |
| Mistake fares | Not called out specifically | Flagged the moment we catch one |
| The judgment call | Yours — you decide if a price move is worth acting on | Already made — only real drops reach your inbox |
Neither tool books anything for you. Both point you back to book the fare wherever it actually lives — including, often, straight through Google Flights itself.
Where each one fits
Google Flights tracking is genuinely good for a single trip you’re actively watching right now — you’ve basically decided you’re going, you’re just timing the click. Set it, get every update, decide for yourself.
Flydar is built for the routes you’re not actively watching — the “I’d go to Lisbon if it were ever actually cheap” trips that would otherwise need you to remember to check back. Set it once, and the only time you’ll hear about it again is when the price has genuinely dropped. Your dates can be exact or loose, your destination can be one city or an entire country’s worth of airports, and none of it needs re-doing when a trip window closes.
The bottom line
If you want every price update for one trip you’re already committed to, Google Flights’ native tracking does that well, for free. If you want to set a route once and only be interrupted when the price actually drops — for a trip today or one you haven’t fully committed to yet — that’s the gap Flydar fills.
