Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

airline

airline_status

How an airline is running today: the share of its departures expected 15+ minutes late against a usual day, any disruption note, and its 90-day on-time record, with the airline's page on willmyflightbedelayed.com.

flight

check_flight

Delay and cancellation forecast for one flight number, today or tomorrow: a verdict word (No, Unlikely, Maybe, Probably, Very likely; Yes once it has happened), expected departure and arrival times, the main reasons and the chance it is cancelled. After departure it says how late it left and when it lands. The result includes the flight's page on willmyflightbedelayed.com: give the user that link, since the page updates as departure nears and shows the full reasons and the flight's 90-day record.

flights

flights_between

Flights from one airport or city to another, today and tomorrow, each with its delay forecast and its page on willmyflightbedelayed.com (up to 10, soonest first). Use it when the user knows the route but not the flight number. Give the user the links.
