- Method
flightaware.com/get_airport_delays- Returns
- airport name and code, date, delayed and cancelled departure and arrival counts and percents, average delays, FAA ground program and reason, weather, temperature, wind, FlightAware link
Use it from your agent
Give your agent this line. It reads SKILL.md, gets a Fous API key and connects the Fous MCP server. Its run then takes the method flightaware.com/get_airport_delays with the inputs above.
Ask your agent
- How many flights are delayed or cancelled at Chicago O'Hare today?
- Is there an FAA ground stop or delay program at SFO right now, and what's the weather there?
- Check FlightAware for today's departure and arrival delays at Atlanta Hartsfield-Jackson
- What percentage of departures out of JFK are delayed today, and what's the average delay?
- Pull up today's delay and cancellation stats for Denver airport on flightaware.com, including wind and temperature

All FlightAware methodsLists the public arrivals or departures FlightAware shows for an airport (name, city, IATA/ICAO code or FlightAware link), with flight times and status. For a city with several airports it picks the busiest listed one and says so; the public board shows up to 20 flights per direction.
flightaware.com/list_airport_flightsChecks the public FlightAware status of an airline flight (airline name or code plus number) on a departure date, by default today at the departure airport: airports, scheduled, estimated and actual gate times in local time, delays, gates, terminals, aircraft and distance. A date older than FlightAware's public two-week list is looked up on the flight's history page when FlightAware still shows it.
flightaware.com/check_flight_statusGets current FAA delay and closure events for a US airport, found by name, city or code. A city with several airports resolves to one of them, and reported delays may not cover every flight.
faa.gov/get_airport_delaysLists upcoming departures or arrivals at an airport from the Flightradar24 public airport board, with local times, airline, route, status and aircraft.
flightradar24.com/list_airport_flightsChecks a flight's public status and times on Flightradar24 by flight number and the departure date at the origin airport.
flightradar24.com/check_flight_statusLooks up today's crowd-sourced security wait estimate and hourly pattern for a US airport by name, city or code, with PreCheck status and checkpoints.
tsawaittimes.com/get_security_wait_timeGets daily weather and time-ordered airport observations for a past date near a city, airport, or ZIP code. Summary averages use the available observations; missing measurements are null.
