How does a query count toward pricing?

Historical Flight Status API:

We charge by the number of flights returned for the Historical Flight Status by Route API and the Historical Flight Status by Airport API. So if you make one historical airport query that returns 120 flights, we charge you 120 x the per historical flight returned rate. There is a surcharge if you also request the historical event timeline for all the updates we received. 


Alerts API:

A single flight rule may send out dozens of alerts (example: a significantly delayed flight may send out many more flight alerts than a routine flight that departs on time). You are not charged for flight rules that you delete prior to our system sending a flight event to the ruleId on your behalf (example: you will not be charged if you delete it before our system sends you any callbacks). We do not charge you extra if you receive multiple callbacks on the same ruleId.
