FlightGuard
Know before you go —
is your flight at risk?
Find out in 2 seconds if your flight risks delay or cancellation. We analyze 9 real signals — weather, strikes, ATC, NOTAMs and more — sharpest in the 24 hours before departure. Free email alerts the moment anything changes.
Data from EUROCONTROL · OpenMeteo · FlightAware · GDELT — refreshed every 15 minutes
Three steps and you'll know what to expect
Enter the flight number
FR5121, BA553, IB3170… any commercial flight works. No account, no forms.
Pick the departure date
Risk shifts day by day: 3 days out the weather is solid, 2 weeks out it's still a guess.
See the risk, set an alert
0–100 score in plain English. If anything gets worse, we email you.
10 signals that actually matter
Not a generic grade: each factor has its own weight, so you see exactly what's hurting your flight.
Fuel
When jet fuel spikes or supply tightens at an airport, airlines start cutting flights. We track it every 6 hours.
Weather
Wind, snow, fog at your destination: the number one cause of delays. Forecast up to 16 days out.
Punctuality
How on-time this airline really runs on this route. Hard numbers, not marketing.
ATC delays
EUROCONTROL publishes air traffic control delays: we pull them in every 6 hours.
Strikes
Pilots, ground handlers, controllers — we catch strikes the moment they're announced.
NOTAMs
Closed runways, restricted airspace, ongoing works. Everything the airline already knows.
Trend
Have recent flights on this number been getting worse? Often the first sign something's off.
Time of day
Delays pile up through the day and cluster on Fridays and Sundays. We weigh your departure slot and weekday.
Geopolitics
Airspace closures, conflicts, restrictions: when geopolitics touches your route, you'll know.
Route history
What happened to similar flights on the same route in recent weeks.

Clear answers to your questions
How does the FlightGuard risk score work?
We tell you in 2 seconds how likely your flight is to be delayed or cancelled. We analyze 10 real-time factors — flight trend, route history, time of day, airline punctuality, ATC delays, strikes, weather, NOTAMs, fuel and geopolitics — and combine them into a 0–100 score. Below 15 you can relax, 15–34 keep an eye on it, 35+ start thinking about a Plan B.
Which flights can I check?
Any commercial flight with a valid flight number (e.g. AA100, DL202, UA328, WN1, FR5121, BA553). The analysis works for US domestic and international flights as well as European carriers, using real-time data from up to 9 factors.
Is the service free?
Yes, completely. No signup, no credit card, no paywall. Enter the flight, pick the date, see the result. Want an alert? That's free too.
How are the 10 risk factors calculated?
Each factor is weighted by how much it actually drives delays: flight trend (18%), route history (18%), time of day and weekday (15%), airline punctuality (14%), ATC delays (10%), strikes (10%), weather (9%), NOTAMs (2%), fuel (2%), geopolitics (2%). Data comes from institutional sources — EUROCONTROL, OpenMeteo, FlightAware, GDELT — refreshed every 15–30 minutes.
Can I get an alert if the risk changes?
Yes. After checking your flight you leave your email and we ping you if the score moves by 5 or more points. One email per meaningful change, never spam. Unsubscribe in one click.
Is the data reliable?
Yes. We only use institutional and public sources: EUROCONTROL for ATC, OpenMeteo for weather, GDELT for strikes and geopolitics, FlightAware for flight history. The algorithm has been validated on more than 7 million real flights. Just remember: the risk score is an informed estimate, not a substitute for the airline's official communications.
Is my email used for marketing?
Never. Your email is used only to send you the alerts you requested. No newsletters, no promos, no third parties. We delete it automatically 30 days after your flight. You can remove it sooner anytime.
